The Overview page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.
Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:
- Interfaces (italic)
- Classes
- Exceptions
- Errors
Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:
Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.
- Class inheritance diagram
- Direct Subclasses
- All Known Subinterfaces
- All Known Implementing Classes
- Class/interface declaration
- Class/interface description
- Nested Class Summary
- Field Summary
- Constructor Summary
- Method Summary
- Field Detail
- Constructor Detail
- Method Detail
Each documented package, class and interface has its own Use page. This page describes what packages, classes, methods, constructors and fields use any part of the given class or package. Given a class or interface A, its Use page includes subclasses of A, fields declared as A, methods that return A, and methods and constructors with parameters of type A. You can access this page by first going to the package, class or interface, then clicking on the "Use" link in the navigation bar.
There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting withjava.lang.Object. The interfaces do not inherit fromjava.lang.Object.
- When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.
- When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.
The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.
The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.
This help file applies to API documentation generated using the standard doclet.

java.lang.Object
jTDS implementation of the java.sql.DatabaseMetaData interface.
Implementation note:
This is basically the code from the original jTDS driver. Main changes relate to the need to support the new ResultSet implementation.
TODO: Many of the system limits need to be revised to more accurately reflect the target database constraints. In many cases limits are soft and determined by bytes per column for example. Probably more of these functions should be altered to return 0 but for now the original jTDS values are returned.

static int calculateNamedPipeBufferSize(int tdsVersion,
int packetSize)
InputStream
for named pipes.
The buffer size is tied directly to the packet size because each request
to the SmbNamedPipe will send a request for a particular
size of packet. In other words, if you only request 1 byte, the
SmbNamedPipe will send a request out and only ask for 1 byte
back. Buffering the expected packet size ensures that all of the data
will be returned in the buffer without wasting any space.
tdsVersion - the TDS version for the connectionpacketSize - requested packet size for the connection
packetSize == 0,
else packetSize

Interface for a statement cache. Abstraction of the caching mechanism by use of this interface will allow developers to create custom caching schemes that are optimal for their specific applications. Any synchronization required by an implementation should utilize the implementing object for the lock.
There are two types of attributes that the cache is concerned with:
String generated from the SQL query for which the
prepared statement was created, the database name and the parameter
types; this key uniquely identifies a server-side preparation of the
statement and is used to retrieve the handle of the statement when it
needs to be executedsp_prepare or
sp_cursorprepare handle on the serverPreparedStatement can map to multiple handles, depending on
the types of the parameters it is called with (hence the need to be able
to map both keys and SQL strings to handles)The caching types provided by jTDS should be:

public void testNullOutputParameters()
throws java.sql.SQLException
null output parameters are handled correctly.
It seems that if a non-nullable type is sent as input value and the
output value is NULL, SQL Server (not Sybase) gets confused and returns
the same type but a single 0 byte as value instead of the equivalent
nullable type (e.g. instead of returning an INTN with
length 0, which means it's null, it returns an INT4
followed by a single 0 byte). The output parameter packet length is also
incorrect, which indicates that SQL Server is confused.
Currently jTDS always sends RPC parameters as nullable types, but this
test is necessary to ensure that it will always remain so.

java.lang.Object
Manages a buffer (backed by optional disk storage) for use as a data store by the CLOB and BLOB objects.
The data can be purely memory based until the size exceeds the value dictated by thelobBuffer URL property after which it will be
written to disk. The disk array is accessed randomly one page (1024 bytes)
at a time.
This class is not synchronized and concurrent open input and output
streams can conflict.
Tuning hints:
PAGE_SIZE governs how much data is buffered when
reading or writing data a byte at a time. 1024 bytes seems to work well
but if very large objects are being written a byte at a time 4096 may be
better. NB. ensure that the PAGE_MASK and
BYTE_MASK fields are also adjusted to match.
MAX_BUF_INC value. Every time the buffer is
expanded the existing contents are copied and this may get expensive
with very large BLOBs.

java.lang.Object
This class would be better implemented as a java.lang.reflect.Proxy. However, this feature was not added until 1.3 and reflection performance was not improved until 1.4. Since the driver still needs to be compatible with 1.2 and 1.3 this class is used to delegate the calls to a statement with minimal overhead.

java.lang.Object
This class would be better implemented as a java.lang.reflect.Proxy. However, this feature was not added until 1.3 and reflection performance was not improved until 1.4. Since the driver still needs to be compatible with 1.2 and 1.3 this class is used to delegate the calls to a prepared statement with minimal overhead.

Windows Single Sign On in jTDS
~~~~~~~~~~~~~~~
Patch Submitted by Magendran Sathaiah (mahi@aztec.soft.net)
===============================================================================
Introduction
============
This document describes the design of the Single Sign On implementation in
the jTDS JDBC driver.
Releases 0.9.1 and earlier of jTDS driver support Windows authentication by
means of the NTLM protocol. That is, clients using the JDBC Driver passes
a valid Windows-Domain-Name, a Windows User and Windows Password; the JDBC
driver will submit these to Microsoft SQL Server via NTLM protocol in order
to gain access to the database. (This approach still works with all later
versions, allowing Windows Authentication to work for non-Windows clients
or clients that don't/can't have the native library installed.)
In the above approach the client will have to maintain a configuration file
to keep the windows logon credentials. That is, the domain name, user name
and password need to be stored in encrypted or plain text format. This
might not be an acceptable solution for everybody.
Starting with release 0.9.2 jTDS is capable of using the Windows
credentials of the current user under whose account the client program is
running to login to SQL Server (Windows Single Sign On).
Using Windows Single Sign On (SSO) clients will be able to connect to
Microsoft SQL Server without providing credentials. It would dynamically
read current user's credentials and connect to the database. provided that
the Windows account has enough rights in the database. This is done using a
native (Windows-only) library, ntlmauth.dll.
Installation
============
In order for Single Sign On to work, jTDS must be able to load the native
SPPI library (ntlmauth.dll). Place this DLL anywhere in the system path
(defined by the PATH system variable) and you're all set.
Usage
=====
In order to set up the jTDS driver to use Windows Single Sign On, users
will have to connect without providing a user name and password. This will
only work on Windows.
Driver example:
// No user name or password in URL or as parameters
DriverManager.getConnection(
"jdbc:jtds:sqlserver://localhost:1433/LionKing");
DataSource example:
ds = new JtdsDataSource();
ds.setDescription("test");
// MS SQL Server Host Name
ds.setServerName("localhost");
// Port
ds.setPortNumber(1433);
// Database Name
ds.setDatabaseName("LionKing");
// No domain name
// No user name
Connection conn = ds.getConnection();
Design
======
The patch comprises the following components:
1. ntlmauth.dll
A CPP Program that uses SSPI Windows APIs to accquire credentials and
NTLM messages from the Windows Operating System.
2. SSPIJNIClient.java
A Java Native Interface class that bridges jTDS JDBC driver and
ntlmauth.dll.
3. Modified Version jTDS source files.
A set of modified jTDS java files that make use of the
SSPIJNIClient.java when the driver is set to use Windows Single Sign On.
SSPIJNIClient.java
==================
It loads the DLL (ntlmauth.dll) in a static block. The ntlmauth.dll must be
available in the system path (defined by the system variable PATH). It
exposes the following APIs:
public static SSPIJNIClient getInstance() throws Exception;
Retuns the singleton SSPIJNIClient object.
private native void initialize();
Initializes the SSPI Client.
private native void unInitialize();
Uninitializes the SSPI client.
private native byte[] prepareSSORequest();
Prepares NTLM TYPE-1 message and returns it as a byte[].
private native byte[] prepareSSOSubmit(byte[] challengeBuf, long size);
Prepares NTLM TYPE-3 message using current user's credentials. It needs
the challenge BLOB and its size as input. The challenge BLOB is nothing
but the TYPE-2 message that is received from the SQL Server.
API Usage:
----------
ntlmAuthSSO = (user == null || user.length() == 0);
if (ntlmAuthSSO) {
sspiJNIClient = SSPIJNIClient.getInstance();
ntlm1 = sspiJNIClient.invokePrepareSSORequest();
}
// 1.ntlm1 contains Type-1 message now
// 2.Send Type-1 Message to the server
//
// 3.MS SQL Server replies back with Type-2 message
// 4.Read Type-2 Message in (say) ntlm2
ntlm3 = sspiJNIClient.invokePrepareSSOSubmit(ntlm2);
//1.now, ntlm3 contains Type-3 message
//2.Send, Type-3 message to the Server.
//3.Check the status - Success | Failure.
Modifications to jTDS Classes
=============================
The TdsCode.java has been modified as follows
1. Member boolean variable: ntlmAuthSSO
A flag that is used to indicate if the client wants to do Windows
Single Sign On. The variable is set in the logon(...) as below
ntlmAuthSSO = (user == null || user.length() == 0);
Note: The user must leave the user name (and password) unset or set
them to null or a blank string to instructthe driver to use
Windows Single Sign On.
2. Member Variable: sspiJNIClient
A reference to the single-ton object of SSPIJNIClient.class
It gets initialzied in logon(..) if ntlmAuthSSO is true.
3. login(..)
At the begining of the method check if Windows Single Sign On is
requested (ntlmAuth == true)
If so initialize the SSPI client and prepare NTLM TYPE-1 message
4. send70Login(..)
Modified to accept an additional byte[] parameter to pass the NTLM
Type-1 message.
Set the authLen = ntlmMessage.legnth() if ntlmAuthSSO is true
5. sendNtlmChallengeResponse(...)
If ntlmAuthSSO is true, then read the Type-2 message from
authToken.getNTLMMessage()
Prepare Type-3 message as below
type3 = sspiJNIClient.invokePrepareSSOSubmit(type2)
Then append it to the command buffer.

sp_cursoropen
Defines the attributes of an API server cursor, such as its scrolling behavior
and the statement used to build the result set on which the cursor operates,
then populates the cursor. The statement can contain embedded parameters.
Syntax
sp_cursoropen [@cursor =] cursor_handle OUTPUT,
[@stmt =] 'stmt'
[, [@scrollopt =] scroll_options OUTPUT]
[, [@ccopt =] concurrency_options OUTPUT]
[, [@rowcount =] rowcount OUTPUT]
[
{, [@paramdef =] N'parameter_name data_type
[,...n]' }
{, [@param1 =] value1 [,...n]
}
]
Arguments
- [@cursor =] cursor_handle OUTPUT
- Is the name of a declared integer variable to receive the cursor handle.
cursor_handle is int, with no default.
- [@stmt =] 'stmt'
-
Is a string containing a single SELECT statement or a single stored procedure
call. The size of the string is limited only by available database server
memory. stmt can contain parameters having the same form as a variable
name, for example:
'SELECT * FROM Employees WHERE EmployeeID = @IDParameter'
Each parameter included in stmt must have a corresponding entry
in both the @paramdef parameter definition list and the parameter
values list.
- [@scrollopt =] scroll_options OUTPUT
- Is the cursor scroll type. scroll_options is int with a default
of 1 (keyset-driven), and can be a combination of these values (exactly one
of the first 5 must be specified).

rows. rowcount is int with no default value.
- [@paramdef =] N'parameter_name data_type [,...n]'
- Is one string that contains the definitions of all parameters that have
been embedded in stmt. Each parameter definition consists of a parameter
name and a data type. n is a placeholder indicating additional parameter

- Is a placeholder for the values of additional parameters. Values can be
only constants or variables. Values cannot be more complex expressions such
as functions, or expressions built using operators.
Return Code Values
0 (success) or 1 (failure).

Getting Started
What are the class names of the Driver,
DataSource, ConnectionPoolDataSource, XADataSource and
ObjectFactory implementations?

What is the URL format used
by jTDS?
The URL format for jTDS is:
jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]
where <server_type> is one of either 'sqlserver'
or 'sybase' (their meaning is quite obvious), <port>
is the port the database server is listening to (default is 1433 for SQL
Server and 7100 for Sybase) and <database> is the database
name -- JDBC term: catalog -- (if not specified, the user's default database
is used). The set of properties supported by jTDS is:
appName (default - "jTDS")- Application name. No practical use, it's displayed by Enterprise Manager
or Profiler associated with the connection.
batchSize (default - 0 for SQL Server;
1000 for Sybase)- Controls how many statements are sent to the server in a batch.
The actual batch is broken up into pieces this large that are sent
separately. The reason for this is to avoid Sybase "hangs" caused by
running out of space with very large batches. The problem doesn't
seem to occur with SQL Server, hence the default limit of 0
(unlimited) in this case.
bindAddress (default - determined by the Java
implementation; requires Java 1.4 or later)- Specifies the local IP address to bind to for outgoing TCP/IP
connections to the database. Useful for multi-homed systems (those with
more than one external IP address) where the default IP address picked by
Java will not connect to the database. Currently has no effect when
using named pipes to connect to a database (see
namedPipe). Since after jTDS-1.2.
bufferDir (default - System.getProperty("java.io.tmpdir"))- Controls the destination where data is buffered to disk.
See also bufferMaxMemory and bufferMinPackets.
bufferMaxMemory (default - 1024)- Controls the global buffer memory limit for all connections (in
kilobytes). When the amount of buffered server response packets
reaches this limit additional packets are buffered to disk; there is
however one exception: each
Statement gets to buffer at
least <bufferMinPackets> to memory before this
limit is enforced. This means that this limit can and will usually be
exceeded.
Server responses are buffered to disk only when a request is made on
a Statement while another Statement
belonging to the same Connection still hasn't processed all its
results. These situations can be avoided in most cases by setting the
useCursors property, but this will also affect
performance.
See also bufferMinPackets.
bufferMinPackets (default - 8)- Controls the minimum number of packets per statement to buffer to
memory. Each
Statement will buffer at least this many
packets before being forced to use a temporary file if the
<bufferMaxMemory> is reached, to ensure good
performance even when one Statement caches a very large
amount of data.
Server responses are buffered to disk only when a request is made on
a Statement while another Statement
belonging to the same Connection still hasn't processed all its
results. These situations can be avoided in most cases by setting the
useCursors property, but this will also affect
performance.
See also bufferMaxMemory.
cacheMetaData (default - false)- When used with prepareSQL=3, setting this property to
true will cause the driver to cache column meta data for
SELECT statements. Caching the meta data will reduce the processing
overhead when reusing statements that return small result sets that
have many columns but may lead to unexpected errors if the database
schema changes after the statement has been prepared. Use with care.
Only applicable to SQL Server (there is no prepareSQL=3 mode for
Sybase).
charset (default - the character set the server was installed
with)- Very important setting, determines the byte value to character mapping
for
CHAR/VARCHAR/TEXT values.
Applies for characters from the extended set (codes 128-255). For
NCHAR/NVARCHAR/NTEXT values
doesn't have any effect since these are stored using Unicode.
domain- Specifies the Windows domain to authenticate in. If present and the
user name and password are provided, jTDS uses Windows (NTLM)
authentication instead of the usual SQL Server authentication (i.e.
the user and password provided are the domain user and password).
This allows non-Windows clients to log in to servers which are only
configured to accept Windoes authentication.
If the domain parameter is present but no user name and
password are provided, jTDS uses its native Single-Sign-On library
and logs in with the logged Windows user's credentials (for this to
work one would obviously need to be on Windows, logged into a domain,
and also have the SSO library installed -- consult README.SSO in the
distribution on how to do this).
instance- Named instance to connect to. SQL Server can run multiple so-called
"named instances" (i.e. different server instances, running on different
TCP ports) on the same machine. When using Microsoft tools, selecting
one of these instances is made by using "<host_name>\<instance_name>"
instead of the usual "<host_name>". With jTDS you will have to
split the two and use the instance name as a property.
lastUpdateCount (default - true)- If
true only the last update count will be returned by
executeUpdate(). This is useful in case you are updating
or inserting into tables that have triggers (such as replicated tables);
there's no way to make the difference between an update count returned
by a trigger and the actual update count but the actual update count
is always the last as the triggers execute first. If false
all update counts are returned; use getMoreResults() to
loop through them.
lobBuffer (default - 32768)- The amount of LOB data to buffer in memory before caching to disk. The
value is in bytes for
Blob data and chars for Clob
data.
loginTimeout (default - 0 for TCP/IP connections
or 20 for named pipe connections)- The amount of time to wait (in seconds) for a successful connection
before timing out.
If a TCP/IP connection is used to connect to the database and Java 1.4 or
newer is being used, the loginTimeout parameter is used to set
the initial connection timeout when initially opening a new socket. A value
of zero (the default) causes the connection to wait indefinitely, e.g.,until
a connection is established or an error occurs. See also
socketTimeout.
If a named pipe connection is used (namedPipe is
true) and loginTimeout is greater than zero, the
value of loginTimeout is used for the length of the retry period
when "All pipe instances are busy" error messages are received while
attempting to connect to the server. If loginTimeout is zero
(the default), a value of 20 seconds is used for the named pipe retry
period.
macAddress (default - "000000000000")- Network interface card MAC address. It's displayed by Enterprise
Manager or Profiler associated with the connection and is needed to
resolve some issues regarding the number of clients allowed by the
SQL Server license. The MAC address cannot be determined automatically
from Java (i.e. without using native code) so you'll have to specify
it yourself if you need it.
maxStatements (default - 500)- The number of statement prepares each connection should cache.
A value of
0 will disable statement caching.
A value of Integer.MAX_VALUE (2147483647)
will enable fast caching (uses less memory and has no overhead
associated with removing statements); the cache will never release
any cached statements, so although experience has shown that this is
usually not a problem with most applications, use with care.
namedPipe (default - false)- When set to
true, named pipe communication is used to
connect to the database instead of TCP/IP sockets. When the
os.name system property starts with "windows"
(case-insensitive), named pipes (both local and remote) are accessed
through the Windows filesystem by opening a RandomAccessFile
to the path. When the SQL Server and the client are on the same machine,
a named pipe will usually have better performance than TCP/IP sockets
since the network layer is eliminated. Otherwise the
JCIFS library is used. JCIFS
provides a pure Java named pipe implementation and uses NTLM
authentication, so the domain parameter is required.
This feature supports the instance parameter (which changes
the named pipe URL), but it does not currently support the named pipe at
a location other than /sql/query on the server. The
port parameter is ignored if set.
packetSize (default - 4096 for TDS 7.0/8.0;
512 for TDS 4.2/5.0)- The network packet size (a multiple of 512).
password (required)- Password to use for login. When using
getConnection(String url,
String user, String password) it's not required to set this property
as it is passed as parameter, but you will have to set it when using
getConnection(String url, Properties info) or JtdsDataSource.
prepareSQL (default - 3 for SQL Server,
1 for Sybase)- This parameter specifies the mechanism used for Prepared Statements.
Value Description 0SQL is sent to the server each time without any preparation, literals are inserted in the SQL (slower) 1Temporary stored procedures are created for each unique SQL statement and parameter combination (faster) 2sp_executesql is used (fast) 3sp_prepare and sp_cursorprepare are used in conjunction with sp_execute and sp_cursorexecute (faster, SQL Server only)
progName (default - "jTDS")- Client library name. No practical use, it's displayed by Enterprise
Manager or Profiler associated with the connection.
processId (default - 123)- The client process ID associated with the connection. Must be an integer
value or the string "compute" to let jTDS choose a process ID.
sendStringParametersAsUnicode (default - true)- Determines whether string parameters are sent to the SQL Server database
in Unicode or in the default character encoding of the database. This
seriously affects SQL Server 2000 performance since it does not automatically
cast the types (as 7.0 does), meaning that if a index column is Unicode
and the string is submitted using the default character encoding (or
the other way around) SQLServer will perform an index scan instead of
an index seek. For Sybase, determines if strings that cannot be encoded in
the server's charset are sent as unicode strings. There is a performance
hit for the encoding logic so set this option to false if unitext or univarchar
data types are not in use or if charset is utf-8.
socketTimeout (default - 0)- The amount of time to wait (in seconds) for a server response before timing out.
Use with care! If a non zero value is supplied this must be greater than the maximum
time that the server will take to answer any query. Once the timeout value is exceeded
the network or named pipe connection will be closed. This parameter may be useful for
detecting dead network connections in a pooled environment. See also
loginTimeout. If using named pipes via JCIFS the timeout cannot be
disabled completely. A timeout of about 25 days (2^31 ms) is applied instead.
socketKeepAlive (default - false)- true to enable TCP/IP keep-alive messages
ssl (default - off)- Specifies if and how to use SSL for secure communication.
Value Description offSSL is not request or used; this is the default requestSSL is requested; if the server does not support it then a plain connection is used requireSSL is requested; if the server does not support it then an exception is thrown authenticateSame as require except the server's certificate must be signed by a trusted CA
tcpNoDelay (default - true)true to enable TCP_NODELAY on the socket;
false to disable it.TDS (default - "8.0" for SQL Server;
"5.0" for Sybase)- The version of TDS to be used. TDS (Tabular Data Stream) is the protocol
used by Microsoft SQL Server and Sybase to communicate with database
clients. jTDS can use TDS 4.2, 5.0, 7.0 and 8.0. Version 4.2 is used by
SQL Server 6.5 and Sybase 10. Version 5.0 is used with Sybase 11 onwards.
Version 7.0 is used by SQL Server 7.0; this protocol also works with SQL
Server 2000. Version 8.0 is used by SQL Server 2000 and SQL Server 2005.
Newer database server versions usually understand older protocol versions.
This means that SQL Server 7.0 can be used with TDS 4.2, but the limitations
of the protocol apply regardless of the server version (e.g. when using TDS
4.2 VARCHARs are limited to 255 characters). As a conclusion,
you must set this property to "4.2" when connecting
to SQL Server 6.5 or Sybase. You should not set this value to
"7.0" or "8.0") when connecting to any
version of Sybase as these are SQL Server specific protocols. Further, you
should not set this value to "5.0") when connecting
to any version of SQL Server as this is a Sybase specific protocol.
Currently jTDS automatically falls back from 8.0 to 7.0 (if used with
SQL Server 7.0) and from 5.0 to 4.2 (with Sybase 10) so specifying
the value for this parameter is only necessary for SQL Server 6.5.
useCursors (default - false)- Instructs jTDS to use server side cursors instead of direct selects
(AKA firehose cursors) for forward-only read-only result sets (with
other types of result sets server- or client-side cursors are always
used).
With firehose cursors the SELECT query is sent and the server
responds with all the resulting rows. This is the fastest approach
but it means that the driver has to cache all results if another
request needs to be made before all rows have been processed. So when
using multiple Statements per Connection it
is preferable to have server-side cursors instead; these will allow
the driver to request only a limited number of rows at a time
(controllable through the fetchSize property of a
Statement). This means extra request-response cycles,
but less caching by the driver.
With SQL Server a so called
fast
forward-only cursor will be created when this property is set to
true. With Sybase a usual forward-only read-only cursor
is created.
useJCIFS (default - false)- Controls whether the jCIFS
library will be used instead of the local file system with named pipe
connections on the Windows operating system. (The jCIFS library will
always be used with named pipes when the operating system is not
Windows.) Useful when connecting via named pipes to a server that is
located in a different domain than the client. See also
namedPipe. Since after jTDS-1.2.
useLOBs (default - true)- Controls whether large types (IMAGE and TEXT/NTEXT) should be
mapped by default (when using
getObject()) to LOBs or
Java types (String and byte[]). The default
JDBC type constant returned is also controlled by this property:
Types.BLOB for IMAGE and Types.CLOB for
TEXT/NTEXT when true, Types.LONGVARBINARY
for IMAGE and Types.LONGVARCHAR for TEXT/NTEXT when
false.
This is useful when printing out directly the values returned by
getObject() (e.g. when using JSTL or other frameworks),
as Blob and Clob don't implement
toString() (both because it's not required and because
it can easily lead to OutOfMemoryErrors in unexpected
situations, such as when logging data). The default setting of
true has the advantage that the amount of data that is
cached in memory for a large object can be controlled via the
lobBuffer property; a setting of false will
still use the Blob and Clob implementations
internally but the values will be materialized to memory when
getObject() is called, possibly leading to memory
issues.
useNTLMv2 (default - false)- Set to
true to send LMv2/NTLMv2 responses when using
Windows authentication
user (required)- User name to use for login. When using
getConnection(String
url, String user, String password) it's not required to set this
property as it is passed as parameter, but you will have to set it when
using getConnection(String url, Properties info) or
JtdsDataSource.
wsid (default - the client host name)- Workstation ID. No practical use, it's displayed by Enterprise
Manager or Profiler associated with the connection.
xaEmulation (default - true)- When set to
true, emulate XA distributed transaction
support, when set to false use experimental true
distributed transaction support. True distributed transaction support
is only available for SQL Server 2000 and requires the installation
of an external stored procedure in the target server (see the
README.XA file in the distribution for details).
Properties can be passed to jTDS in one of three ways: in the URL, in
the Properties object passed to getConnection()
or by using the JtdsDataSource's setters (if connections are
obtained through a DataSource rather than using the
DriverManager). Because there is no URL when using the
JtdsDataSource there are three other properties (with
setters and getters) to take the place of those items that are part of
the URL's syntax: serverName, portNumber and
databaseName (their meaning should be quite clear).
jTDS is supposed to be the
fastest JDBC driver around. Have you got any figures to prove that? Or
even better, a benchmark I can run myself?
Actually we do have benchmark results from two different benchmarks,
both developed by large commercial SQL Server JDBC driver vendors to
demonstrate the performance of their own drivers. In our oppinion this
is better than having a benchmark of our own, which could be designed
in such a way as to give jTDS the edge. These benchmarks are free to
download so we encourage you to do it and run them yourself.
We have benchmarked jTDS against the two most used commercial drivers
and of course the Microsoft driver and the JDBC-ODBC bridge, using these
benchmarks:
i-net
software's BenchTest 2.1 for MS SQL Server and
JNetDirect's
JDBC Performance Benchmark. Here are the results of the i-net test:
BenchTest 2.1 for MS SQL Server. The JNetDirect
license precludes publication of performance test results. However, you
can run any of the benchmarks yourself, the effort is minimal.
Which JDBC features are and
which features are not supported by jTDS?
jTDS offers full support for all JDBC 3.0 features:
forward-only and scrollable/updateable result
sets, batch updates, prepared and callable
statements, unlimited number of statements per connection, complete
database and result set meta data, and a DataSource
implementation (which also implements ConnectionPoolDataSource
and XADataSource). Features such as generated keys
retrieval, named stored procedure parameters, and save points are also
implemented.
The only major features missing from jTDS are connection pooling and
row sets; the reason for leaving these out is that there are free
implementations available, probably much better than anything we could
come up with. Check out the jTDS feature
matrix for more details.
Can jTDS be used in a
multi threaded application?
As a general principle we try and keep synchronization to a minimum
both for performance and deadlock reasons. The only part of jTDS we
guarantee is thread safe is the Connection object, and
multi threaded access to Statements is discouraged (except
for issuing cancels).
As a conclusion the only safe multithreading scenarios are these: (i)
one Connection with multiple Statements, each
Statement used by a single thread and (ii) a
Statement used by one thread and cancelled by some other
thread. Scenario (i), while it does work, is not necessarily a good
solution because it requires a lot of locking and waiting on the same
network connection plus (last but not least) a lot of caching.
Error Conditions
Why do I get a
ClassNotFoundError when calling
Class.forName("net.sourceforge.jtds.jdbc.Driver")?
ClassNotFoundError is thrown by the classloader when it
can not find a certain class. In this case it's the
net.sourceforge.jtds.jdbc.Driver class, which means that
jtds.jar is not in the classpath. If you are getting this
in an application, start your application with
java -cp <path_to_jtds>/jtds.jar <main_class>
If you experience this problem in a servlet/JSP you will have to add
jtds.jar to your web application's class path (e.g. by
editing the application's web.xml file or by copying the jar into the
application's/server's /lib directory).
Note: The name of the jTDS jar file may be jtds-1.2.jar
or something similar. If that's the case, replace jtds.jar
in the above example with jtds-1.2.jar or whatever your specific
file name is.
Why do I get a java.sql.SQLException:
"No suitable driver" when trying to get a connection?
The "No suitable driver" exception is thrown by
the DriverManager when none of the registered Driver
implementations recognizes the supplied URL. This means that you either
did not register jTDS with the DriverManager first (by calling
Class.forName("net.sourceforge.jtds.jdbc.Driver"))
or you mistyped the URL (e.g. "jbdc:jtds:..."
instead of "jdbc:jtds:...").
A common mistake is to append a semicolon (";") to the end of the URL
(e.g. "jdbc:jtds:sqlserver://server/db;TDS=7.0;" is wrong!).
For more information about URL format and the properties that may be
passed to jTDS have a look at the jTDS URL format.
Why do I get
java.sql.SQLException: "Network error IOException: Connection
refused: connect" when trying to get a connection?
The "Connection refused" exception is thrown by
jTDS when it is unable to connect to the server. There may be a number
of reasons why this could happen:
- The server name is misspelled or the port number is incorrect.
- SQL Server is not configured to use TCP/IP. Either enable TCP/IP
from SQL Server's Network Utility app or have jTDS connect via named
pipes (see the URL format for information on
how to do this).
- There is a firewall blocking port 1433 on the server.
To check whether TCP/IP is enabled and the port is not blocked you can
use "telnet <server_host> 1433". Until telnet doesn't connect,
jTDS won't either. If you can't figure out why, ask your network
administrator for help.
Where does one place an instance
name in the connect string? Connecting with
"jdbc:jtds:sqlserver://host\instance:port/database" gives an
SQLException with the message "Logon failed".
You will have to use the instance property (either append it to the
URL or place it into the Properties you supply to getConnection)
instead of doing it the Microsoft way. Sorry, but jTDS (and its ancestor
FreeTDS) existed a long time before named instances so the URL could not
be changed (and using it this way confuses the URL parser).
Why do I get a
java.sql.SQLException: "Unable to get information from SQL
Server" when trying to connect to an SQL Server instance?
The exception you are getting is usually caused by a timeout. When
connecting to named instances jTDS needs to connect via UDP to port 1434
to get information about available SQL Server instances. While doing
this it times out, throwing the exception you see (which means that jTDS
was not able to get information about the running instances).
Connection timeouts occur when there is no server listening on the port
(BTW, are you sure your SQL Server is configured to use TCP/IP and that
you actually use named instances?).
On SQL Server 2005 the SQL Browser service must be running on the
server host as the instance name lookup port UDP 1434 is hosted by this
service on SQL Server 2005 rather than the SQL Server itself. The
default install does not configure the SQL Browser service to start
automatically so you must do it manually.
I was hoping that appending
";domain=X" to the URL would be enough on a workstation that
was already logged into domain X. Why do I still need to provide a username
and password?
jTDS is a type 4 (pure Java) JDBC driver. This means (among other things)
that it cannot access platform-specific features, such as determining the
currently logged user and his credentials. jTDS is distributed with a
native library (DLL) for Single-Sign-On support, but that only works on
Windows (please consult README.SSO in the distribution package for
information on how to install it).
Without the native SSO library installed you still have to provide the
username and password because otherwise jTDS cannot determine user
credentials. There is a good side to this: users on non-Windows
platforms are able to log in using Windows credentials by providing
them in the URL, along with the domain name.
executeQuery() throws java.sql.SQLException: "The
executeQuery method must return a result set.".
The JDBC
spec and
API
documentation for Statement both state that
executeQuery() is intended to be used with queries that
return a ResultSet, typically SELECT
statements. On the the other hand, executeUpdate() is
intended for INSERT, UPDATE,
DELETE or DDL statements that return update counts. Both of
these (ResultSets and update counts) are considered by JDBC
to be "results". For queries that return multiple results the JDBC spec
requires execute() to be used.
If you'll look at the query you are trying to execute, you'll see that
it probably returns an update count first, followed by a
ResultSet. So according to the JDBC spec you should use
execute() to run it, call getMoreResults() to
skip the update count and then call getResultSet() to
obtain the ResultSet you want.
As a sidenote, The Microsoft driver (and probably the others, too)
"optimize" this behavior by skipping over the update count, which is
wrong according to the JDBC spec. So, for maximum compatibility, it is
recommended that you use execute() anytime you run queries
returning more than one result even if the particular driver you are
using allows you to do otherwise.
The same thing happens with the ODBC SQL driver and other connectors.
A common solution rather than the inelegant execute() and then cycling
through multiple result sets, is to supress the update counts for
statements you are uninterested in. This is common if say you are
querying a stored procedure that creates a temp table, runs updates
against it and then returns the table as a result set. You can
suppress all the extra "query results" by specifying "SET NOCOUNT
ON".
I get
java.sql.SQLException: "ResultSet may only be accessed in a
forward direction" or "ResultSet is read
only" when using a scrollable/updateable
ResultSet.
There are three possible causes to this (if we exclude not creating
the ResultSet with the appropriate type and concurrency in
the first place):
- The executed query must be a single SELECT statement or a call to a
procedure that consists of a single SELECT statement (even a SET or
PRINT will cause the resulting ResultSet to be forward only read
only). This is a SQL Server limitation and there's not much jTDS can
do about it.
- The scroll insensitive/updateable combination is not supported by
SQL Server, so such a
ResultSet is automatically
downgraded to scroll insensitive/read-only by the server. Use the
scroll sensitive/updateable combination and it should work.
- The other possible cause is that the cursor is keyset-based and
either the table you are selecting from does not have a unique primary
key or that primary key is not included in your
SELECT.
See the
SQL
Server Documentation on cursor types for more information.
In both cases if you call Statement.getWarnings() right
after calling executeQuery() you'll get a warning about the
ResultSet being downgraded. Also, please take a look at
our ResultSet support page
for some additional information and tips.
Not all
SQLExceptions thrown by jTDS seem to have associated
meaningful SQL state values.
Indeed, some SQLExceptions are reported with a correct state code
and some not. As the server itself does not return an SQL state code,
the SQLMessage class associates native error numbers with SQL state
codes (actually there's a very comprehensive map there); SQL Server
originated errors and warnings that are not found in this map are given
a default code of 'S1000', respectively '01000'. This is what happens
with SQL Server-returned errors and warnings and is consistent with how
other drivers handle exceptions. We have done our best to map as many
errors and warnings, however if you find some case in which other JDBC
or ODBC drivers return specific SQL states and jTDS doesn't or jTDS
returned SQL states that are obviously wrong, please let us know. We
will make the necessary changes.
See the
SQL
92 spec for the complete list and description of SQL state
codes.
Batch processing
using executeBatch() hangs or is unreliable on Sybase.
When executing large batches on Sybase the client application may
hang or the response time may vary considerably. The client may be
suspended if the system log fills so check that the log space is
sufficient for the batch you are trying to load. You can control the
real batch size using the batchSize parameter; setting it
to a non-zero value will break up batches into smaller pieces on
execution, hopefully avoiding the problem.
It is also recommended that you execute each batch in a transaction
(i.e. with auto commit set to false).
Incorrect Behavior
CallableStatement output parameter getter throws
java.sql.SQLException: "Parameter X has not been
set.".
When executing a stored procedure (or any query, for that matter) the
response from the SQL Server is serialized in the same order it is
executed in: for stored procedures this means ResultSets
and update counts first, output parameters and return value last. jTDS
only caches update counts , not ResultSets because they
could easily cause OutOfMemoryErrors or add important
performance overheads if cached to disk (the response would have to be
parsed twice, for example).
As a conclusion, when executing stored procedures that only return
update counts output parameters will be available immediately, as jTDS
will process and cache the whole response. But if the stored procedure
returns at least one ResultSet jTDS will only cache the
update counts up to the first ResultSet and you will have
to call getMoreResults() to process all the results. So
for procedures returning ResultSets you will have to loop,
consuming all results before reading the output parameters (i.e. until
getMoreResults() returns false AND
getUpdateCount() returns -1).
In case you are wondering if this is right, this is a quote from the
CallableStatement API documentation: "For maximum
portability, a call's ResultSet objects and update counts
should be processed prior to getting the values of output
parameters". Although this means that a "good" driver could "fix" this
behavior, fixing it would imply caching the whole server response,
equaling a huge performance drop.
The exception is thrown because it's better to warn the user that the
output parameters are not yet set instead of leaving the impression
that all is ok and cause other, harder to detect problems.
PreparedStatement.executeUpdate() returns an incorrect
update count.
This is caused by triggers; replication is also implemented through
triggers, so you will encounter this issue on replicated databases too.
The root cause is that triggers also return update counts and jTDS can't
make the difference between these update counts and the "real"
one (neither could any other SQL Server client). However, the update
count you need is the last of them (because the actual
UPDATE/INSERT/DELETE gets
executed only after the triggers) and there is luckily a parameter you
can specify in the URL (or the connection Properties or in
the DataSource) in order for jTDS to return only this last
update count (and ignore the rest of them). This parameter is
lastUpdateCount and you can find out more about it
here.
Please note that setting lastUpdateCount to
true could cause problems if you use queries that do
actually return more than one update count (such as queries consisting
of multiple updates/inserts), because it will also return only the last
of these update counts. Although queries returning multiple results are
not very common, it is the reason why this behavior is customizable from
the URL. Please note that this flag only alters the behavior of
executeUpdate(); execute() will still return
all update counts.
If you have both queries consisting of multiple
UPDATEs/INSERTs/DELETEs and
triggers you won't be able to set lastUpdateCount to
true if you want all the update counts, so you will have to
skip over the irrelevant update counts by calling
getMoreResults() yourself, when needed.
Why do I get java.sql.SQLException: "Output parameter not allowed
as argument list prevents use of RPC." when calling a stored procedure?
When calling a stored procedure that has output parameters, the driver
has to call the procedure using a remote procedure call (RPC). Stored
procedures should be invoked using the special JDBC call escape syntax.
For example, {call sp_example(?,?)}. In this case the driver will be able
to use an RPC succesfully as all the parameters are represented by
parameter markers (?). If however parameters are supplied as a
mixture of parameter markers and literals, for example {call
sp_example('test',?)}, then the driver is unable to use an RPC
and therefore cannot return output parameters. In these circumstances the
driver raises an exception and execution fails.
It is possible to use mixed parameter lists to call stored procedures
that do not have output parameters. In this case the driver will substitute
the parameters locally and use a normal "execute procedure" SQL
call; however, this mode of execution is less efficient than an RPC.
Memory Usage
Memory usage
keeps increasing when using generated PreparedStatements.
Normally, with a JDBC driver, PreparedStatements are
precompiled on creation, which gives increased performance if they are
used a sufficient number of times. jTDS takes this one step further:
when you create a PreparedStatement, jTDS caches it internally and keeps
it there even after you close it so that every time you create it again
it doesn't need to be recompiled, it's just fetched from the cache. This
gives jTDS a 2x performance increase over the next fastest driver in
some (not so uncommon) cases. For example, if you have a method that
inserts a row into a table by creating a PreparedStatement,
using it once and then closing it, your statement will be compiled only
once for each Connection, no matter how many times you
call that method.
The number of statements that are kept open simultaneously can be
controlled with the maxStatements parameter; see the
jTDS URL format for more information.
Future versions of jTDS will allow the type of cache (LRU, FIFO, etc)
to be selected.
TDS Protocol Version
I'm trying to connect
to SQL Server 6.5, but it hangs when calling getConnection().
jTDS uses by default TDS 8.0 (which is SQL Server 2000's protocol) to
communicate with the database server. When jTDS sends the 8.0 login request
SQL Server 6.5 doesn't understand it so it returns a 4.2 error (Login
failed). But because jTDS is expecting a TDS 8.0 packet as a response
(not a TDS 4.2 packet) it doesn't properly understand the response packet
and it hangs waiting for more data from the server. The solution is to set
the "TDS" property to "4.2"
(through the URL or Properties object passed to getConnection()
or using the appropriate setter of JtdsDataSource, if you
are using the JtdsDataSource).
For more information about URL format and the properties that may be
passed to jTDS have a look at the jTDS URL format.
Why do column names more
than 30 characters long, get chopped off at 30 characters?
You are very probably using TDS 4.2 to communicate with the SQL Server.
TDS 4.2 is the protocol used by SQL Server 6.5 and it has the limitations
of SQL Server 6.5 (among which a maximum column name size of 30 characters).
jTDS 0.2 and earlier use TDS 4.2 by default. In order to change that you
have to specify it explicitly in the Properties or the URL
you supply when you create the connection. If you experience this problem
with versions 0.3 or later, then you have specified (in the connection
properties or URL) that TDS 4.2 should be used; remove that setting.
For more information about URL format and the properties that may be
passed to jTDS have a look at the jTDS URL format.
jTDS fetches only the first
4Kb of IMAGE data.
You are very probably using TDS 4.2 to communicate with the SQL Server.

setting.

passed to jTDS have a look at the jTDS URL format.
What do i have to do to connect
to Netcool Omnibus (or any derived Product).
You are required to use TDS 5.0 to communicate with the Omnibus Server and
set a default charset to avoid SQL errors, so your URL will look like:
jdbc:jtds:sybase://NCO:4100;TDS=5.0;charset=iso_1.
Since the Omnibus Server understands only a limited subset of SQL, you cannot
use prepared Statements.
Technical support
Is there any commercial
technical support available for jTDS?
For the moment you can get official technical support from individual
developers of jTDS; contact any of us and we'll be happy to provide you
with our tech support terms and conditions. Of course, we will keep
offering support on our SourceForge forums just as we did until now; we
are only trying to encourage adoption of jTDS, not make a fortune out
of it.
As for where the technical support money will go, part of them will be
retained by the developer and part of them will go back into jTDS.
Currently the aim is to raise US $2000, to pay for JDBC certification.
We're 100% sure jTDS will pass the certification test suite, we just
need the money for it. To this end, we also accept donations.
Other
I didn't find the answer to my
problem in this FAQ. What should I do?
If you need help with any other jTDS-related issue, search the
Help
forum first and if you still don't find anything, post a question.
It will usually get answered within 24 hours. One thing, though: please
register as a SourceForge member and log in if you haven't done so yet,
so you can be automatically notified of updates to the questions you
post.
If you encountered an issue that you have tested and retested and you're
sure it's a bug, use the Bugs link on top of the page. Again, make sure you
are a SourceForge member AND that you are logged in when you post.

i-net Software BenchTest 2.1 for MS SQL Server Results
These are the results of running i-net Software's BenchTest
2.1 for MS SQL Server. The tests were run against an SQL Server 2000 over
a 100Mbit network connection. The client machine was an AMD Duron 900MHz with
512MB RAM (no idea about the server).
5 drivers were tested: i-net
Merlia 6.0, Microsoft SQL Server Driver for JDBC SP2, JNetDirect JSQLConnect
3.3023, jTDS 0.7 and the JDBC-ODBC bridge bundled with J2RE 1.4.2-b28. All tests
were run twice and the final result is the average of the two test runs.
Unfortunately, the license of NetDirect JSQLConnect does not allow any benchmarking
results to be made public, but it has failed the CursorUpdate test and the results
would not have affected the final standings too much. If you want some more
exact results for JSQLConnect, download it and the i-net Software BenchTest
and do the testing yourself. It's very easy.
Tests run with rowcount = 1000

The tests explained
All tests use a table with an INT primary key and nullable columns of
each SQL Server base type (about 20 in all). The rowcount is a parameter
that determines the size of each test (number of rows inserted/updated/retrieved
or Blob size).
- UnpreparedInsert - Insert rowcount rows with default values with a classic
INSERT using a plain statement.
- DeleteAll - Delete all rows with a single statement ('DELETE FROM Table').
Not very relevant, it only tests the server, that's why the results vary so
wildly from the 1000 rows test to the 100 rows test.
- CursorInsertEmpty - Insert rowcount rows using insertRow() and without setting
the value of any column.
- CursorDelete - Delete rowcount rows using deleteRow().
- CursorInsert - Insert rowcount rows with setting all columns (one column
for each type supported by SQL Server, except TEXT/IMAGE).
- CursorFetchPaged - Create a scrollable ResultSet, set the fetch size to
rowcount/100 and scroll through it. (jTDS doesn't "know" how to
fetch more than one row of a cursor-based ResultSet at once yet, so it's somewhat
slower than the i-net driver, but still a lot faster than the others.)
- CursorUpdate - Update rowcount rows using updateRow().
- PreparedUpdate - Update rowcount rows using a classic UPDATE with a PreparedStatement.
- PreparedUpdateWProc - Update rowcount rows using a stored procedure with
a PreparedStatement.
- BatchPreparedUpdate - Update rowcount rows using a classic UPDATE with a
PreparedStatement and executeBatch() in batches of 10 updates.
- ResultSetReadAllRows - Scroll through a scrollable ResultSet and call the
getXXX() methods for each column.
- PreparedBlobUpdate - Update a Blob of rowcount KB using a classic UPDATE
with a PreparedStatement.
- PreparedBlobUpdateWProc - Update a Blob of rowcount KB using a stored procedure
with a PreparedStatement.
1
MS Cursor stands for the Microsoft driver with SelectMethod set to 'Cursor'
(the other uses the default 'Direct' method).
2 The JDBC-ODBC bridge failed on the CursorDelete
test and closed the connection causing the rest of the tests to also fail.

jTDS result set information
jTDS supports the following result set types on MS SQL Server.
JDBC Type
SQL Server Cursor Type
Server Load
Description
TYPE_FORWARD_ONLY
Firehose cursor (direct select) when read-only
Light
Fast, but driver will have to read all data. Not recommended when using multiple result sets. Forward only.
Fast forward-only (static) cursor when read-only and useCursors=true
Heavy
Slower than firehose cursors (multiple fetch requests), driver doesn't have to read all data. Forward only.
Forward-only dynamic cursor when updatable
Heavy
Others' updates, deletes and inserts visible. Forward only.
TYPE_SCROLL_INSENSITIVE
Static cursor
Heavy
Only works with read-only concurrency (updatable is downgraded). SQL Server generates a temporary table, so changes made by others are not visible. Scrollable.
TYPE_SCROLL_SENSITIVE
Keyset cursor
Medium
Others' updates or deletes visible, but not others' inserts. Scrollable.
TYPE_SCROLL_SENSITIVE+1
Dynamic cursor
Heavy
Others' updates, deletes and inserts visible. Scrollable.
jTDS supports the following result set concurrencies on MS SQL Server.
JDBC Concurrency
SQL Server Concurrency
Row Locks
Description
CONCUR_READ_ONLY
Read only
No
Read-only.
CONCUR_UPDATABLE
Optimistic concurrency, updatable
No
Row integrity checked using timestamp comparison or, when not available, value comparison (except text and image fields).
CONCUR_UPDATABLE+1
Pessimistic concurrency, updatable
Yes
Row integrity is ensured by locking rows.
CONCUR_UPDATABLE+2
Optimistic concurrency, updatable
No
Row integrity checked using value comparison (except text and image fields).
jTDS supports the following result set types on Sybase.
Result Set Type Result Set Concurrency Supported Comments
TYPE_FORWARD_ONLY CONCUR_READ_ONLY Yes Default result set using a direct select.
TYPE_FORWARD_ONLY CONCUR_UPDATEABLE Yes Uses a client side cursor with optimistic locking.
TYPE_SCROLL_INSENSITIVE CONCUR_READ_ONLY Yes Uses a client side cursor.
TYPE_SCROLL_INSENSITIVE CONCUR_UPDATEABLE Yes Uses a client side cursor with optimistic locking.
TYPE_SCROLL_SENSITIVE CONCUR_READ_ONLY Yes Uses a client side cursor.
TYPE_SCROLL_SENSITIVE CONCUR_UPDATEABLE Yes Uses a client side cursor with optimistic locking.
Notes:
- Updateable result sets can only be built from select statements containing one base table.
- Tables used to build CONCUR_UPDATEABLE and/or TYPE_SCROLL_SENSITIVE result sets should have primary keys.
- Use the Statement.getWarnings() and ResultSet.getWarnings() methods to check that the actual result set
returned has not been downgraded, for example from updateable to read only.
- For SQL Server cursors the fetch size defaults to 100 rows while for Sybase the entire result set is cached in the
client. Therefore care must be taken with Sybase to limit the size of result sets to avoid "out of memory" errors.
Support for positioned updates:
- Positioned updates are supported on both SQL Server and Sybase using forward only server cursors.
- For named cursors to be used for positioned updates the fetch size defaults to 1.
- Use the Statement.setCursorName() method to set the cursor name.
- Use the ResultSet.getCursorName() method to obtain the cursor name for use in the "where current of" clause.
- If there is no intention to actually update the cursor then the ResultSet.setFetchSize() method can be used to
increase the fetch size from it's default of 1. This mode allows efficient sequential access to large result sets
without the risk of the driver caching large amounts of data.

Overview
jTDS is an open source 100% pure Java (type 4) JDBC 3.0 driver for
Microsoft SQL Server (6.5, 7, 2000, 2005 and 2008) and Sybase (10, 11,
12, 15). jTDS is based on FreeTDS
and is currently the fastest production-ready JDBC driver for SQL Server
and Sybase. jTDS is 100% JDBC 3.0 compatible, supporting forward-only
and scrollable/updateable ResultSets, concurrent
(completely independent) Statements and implementing all
the DatabaseMetaData and ResultSetMetaData
methods. Check out the feature matrix for
more details.
Quite a few of the commercial JDBC drivers out there are based on jTDS
(or FreeTDS), even if they no longer acknowledge this. jTDS has been
tested with virtually all JDBC-based database management tools and is
the driver of choice for most of these (recommended for
DbVisualizer
and SQuirreL SQL,
distributed with Aqua Data Studio
and DataDino). jTDS is also
becoming a common choice for enterprise-level applications: it passes
both the
J2EE 1.3 certification and Hibernate
test suites, and is recommended for JBoss, Hibernate, Atlassian
JIRA and Confluence
and Compiere.
Getting Started
Being a type 4 driver, jTDS does not need any special installation.
Just drop the jar file into your application's classpath and you're
done. All you need to know is the name of the Driver and
DataSource implementations and the URL format and you're
all set. You can get these and a lot more information from the
Frequently Asked Questions page. For
features needing native libraries such as XA support or Single-Sign-On
consult the specific README files.
Why use jTDS?
jTDS is free software. jTDS is released under the terms of the GNU LGPL, giving you not
only the posibility to debug and tweak it to your own liking but also
to use it in and distribute it with your free or commercial
applications.
The other "free" choices, the JDBC-ODBC bridge and
Microsoft's own JDBC driver are not actually free. If you encounter an
issue with any of them you won't be able to fix it yourself and
response times from both Microsoft and Sun are anything but short.
Also, both of them lack functionality (the Microsoft driver implements
JDBC 2.0, while the bridge is just a JDBC 1.0 implementation) and have
serious stability problems: the bridge crashes the JVM if the ODBC
driver has any problem and Microsoft just has no intention of really
supporting Java/JDBC.
jTDS is also the most performant JDBC driver for both SQL Server and
Sybase. We have an older benchmark result
but we strongly encourage you to download any benchmark published by
commercial JDBC driver vendors and see for yourself. Here are a couple
of benchmarks you could use: JNetDirect's
JDBC Performance Benchmark and i-net
Software's BenchTest 2.1 for MS SQL Server.
Anyway, just give it a spin. Get the latest one from
here
and see whether you like it or not.
Support
Following a number of requests we have decided to offer commercial
technical support for interested parties. For the moment you can get
official technical support from individual developers of jTDS; contact
any of us and we'll be happy to provide you with our tech support terms
and conditions. Of course, we will keep offering support on our
SourceForge forums just as we did until now; we are only trying to
encourage adoption of jTDS, not make a fortune out of it.

Joining jTDS
Although we haven't established a clear policy about accepting new members,
the idea is that interested people usually submit patches and participate
in discussions in the developers forum then when we are convinced that
they are both interested in the project and able to help, they become
full members. We do this because there have been a lot of people in the
past that have become project members and then completely forgot about
jTDS (at one point we had 16 members out of which there was only one constant
contributor and another one dropping in from time to time).
If you don't have access to an SQL Server machine, that's fortunately
no problem. ;o) What this means is that there is a free (reduced but working)
version that you can download from Microsoft, the MSDE (Microsoft Data
Engine) 2000. You can also get MSDE 2000
(which is a reduced version of SQL Server 2000) for testing purposes.
MSDE only contains the (somewhat crippled) database engine and has no
frontend or documentation. As a frontend you can use a JDBC-based tool
(there are some Windows tools too, but I never tried one); I would recommend
either SQuirreL SQL
or iSQL-Viewer (both open source).
The SQL Server Online Books pack (the same that comes with the full SQL
Server) is also available for download on the Microsoft site, I would
recommend you download it too (it's a .chm file, about 10 megs and has
all the public documentation for SQL Server). Then, for more information
(non-public this time, such as TDS protocol) check out the FreeTDS web
site and, of course, jTDS (web site and repository contents). There are
no URLs for the stuff on the Microsoft site because their links tend to
change a lot, but you should be able to find everything using Google (usually
the first result).
And another thing: for any questions you might have, use the forums (whichever
you think suits your question better) so that anyone can answer your question
and later people having the same question can get the answers without
having to ask again.

jTDS Documentation
As you might expect jTDS is not 100% documented, but there is a lot of
information lying around and we are currently working on organizing all
this information into something that's easy to use. For now, there's the
FAQ, the javadoc-generated HTML, the (reverse engineered) TDS 7.0 protocol
specification, various benchmark results and a feature matrix. If you
are interested in helping us or have any kind of related documentation,
please let us know.
Here are the links. For jTDS users:
- The Frequently Asked Questions page. This is
where you'll find the answers to the most common questions but also
detailed information on using jTDS. Check it out first if you never
used jTDS before.
- The jTDS feature matrix. The fastest way
to check whether jTDS has everything you need or not.
- Data types supported by jTDS.
- Benchmark results. We have benchmarked jTDS against some well-known
commercial drivers and of course the Microsoft driver and the JDBC-ODBC
bridge, using two different benchmarks, provided by two leading commercial
driver vendors: i-net
software and JNetDirect.
Here are the results of the i-net test: BenchTest 2.1 for
MS SQL Server. The JNetDirect license precludes publication of performance test results.
However, jTDS is generally faster than all other drivers.
- Information about jTDS
ResultSet
support. What ResultSet types are supported and some
guidelines on how to ensure correct behavior.
For developers and those interested in finding out more about jTDS and/or
SQL Server:
- jTDS API documentation (javadoc-generated). Please
note that this might be somewhat out of date, it's pretty hard remembering
to update it. If you want to make sure you get the last version, go
to the download page and get the jTDS source package. It contains the
last javadoc-generated documentation.
- Some TDS 7.0 documentation. Incomplete (since
it's obtained by reverse-engineering the data stream between SQL Server
and jTDS or various other clients) but it contains enough new information
to make it interesting and useful. Be sure to also check out the documentation
provided by the FreeTDS project, as it pretty much complements the stuff
we have.
- Documentation on SQL Server
API server cursors (i.e. the undocumented stored procedures used
in the background by all the Microsoft client implementations to handle
cursors). This is some pretty new stuff, assembled from scratch by the
jTDS Project, but it's quite complete.
- Interested in joining the project? Here's
a short document describing how you can become a project member. You
don't have to do anything you don't want to, just have fun writing code,
tests, documentation, helping out people or reverse engineer M$'s well
kept secrets.
If you haven't found what you were looking for, make sure to check out
the jTDS forums
or the project trackers (bugs,
patches,
support
requests and requests
for enhancements). Of course, you can also post your question in the
appropriate forum and someone will get back to you as soon as possible.

Thanks
SourceForge.net is the world's largest
open source development support website, with the largest repository
of open source code on the Internet. The jTDS Project and this website
are hosted by SourceForge.net. Our thanks go to the people at SourceForge.
:o)
FreeTDS is a set of libraries for Unix
and Linux that allows programs to natively talk to Microsoft SQL Server
and Sybase databases. jTDS was originally based on the work of the
FreeTDS project. Lots of thanks go to them, too.
Related technologies
JDBCTM
technology is an API that lets you access virtually any tabular data
source from the JavaTM programming
language. It provides cross-DBMS connectivity to a wide range of SQL
databases and also to other tabular data sources, such as spreadsheets
or flat files.
Although we 'love' Microsoft just as much
as you do, it seems like Microsoft SQL Server is one of the most used
database engines. That's why jTDS was started in the first place:
to avoid paying big money for commercial JDBC drivers for MS SQL Server.
Tools
DataDino Database Explorer is a low-cost
commercial JDBC-based database management tool that comes with built-in
support for a variety of databases. The support for MS SQL Server
is provided by jTDS. Jerason Banes, the developer of DataDino is also
a member of the jTDS Project.
SQuirreL SQL Client is an open source
graphical Java program that will allow you to view the structure of
a JDBC compliant database, browse the data in tables, issue SQL commands
etc. SQuirreL SQL is also hosted by SourceForge and it's one of the
top Java projects on SourceForge.
DbVisualizer is a widely-used commercial
database visualization and management tool based on JDBC. Among others,
a nice thing about DbVisualizer is a diagram view of a database displaying
tables and the foreign key relationships between them.
DB Solo is a powerful yet affordable
cross-platform database development and management tool for both
developers and administrators. It allows users to explore and
manage database objects as well as execute ad-hoc queries. DB Solo
supports most operating systems and DBMS products.

TDS 7.0 protocol documentation
This is a try to document the TDS protocol version 7.0. It has a lot of holes, but it
contains a lot of new information over the
documentation furnished by the FreeTDS project.
All this is obtained through reverse engineering and it would be pretty interesting to
match it against the TDS 5.0 documentation, for example. I'm convinced a lot of new
information could be discovered. If anyone is interested in doing this, please contact the
project. We'll be more than happy to provide you with any documentation we have gathered
so far and that cannot be posted here from various reasons.

License
jTDS is Free Software. jTDS is made available under the terms of the
GNU Lesser General
Public License. The
LGPL is
sufficiently flexible to allow the use of jTDS in both open source and
commercial projects. Using jTDS is considered to be dynamic linking;
hence our interpretation of the LGPL is that the use of the unmodified
jTDS source or binary does not affect the license of your application
code.
If you modify jTDS and redistribute your modifications, the LGPL
applies, basically meaning that you'll have to make the modified version
publicly available under the LGPL license too. This ensures that all
users of the software have access to all future improvements.
jTDS was initially based on software released under a BSD license by
CDS Networks, Inc. and/or Craig Spannring, the author of the original
FreeTDS JDBC driver from which jTDS is derived. Between releases 0.8.1
and 0.9 jTDS was completely rewritten so the original BSD license no
longer applies.

============
jTDS is Free Software. jTDS is released under the terms of the GNU Lesser
General Public License. A copy of the LGPL is provided in the LICENSE file. The
LGPL is sufficiently flexible to allow the use of jTDS in both open source and
commercial projects.
This document has been superseded by the HTML documentation that can be found
in the html directory. However, since it still contains pertinent information
it has been left in place. If you are a first time user please read this
document and the HTML FAQ before proceeding. It's also recommended that you
also read at least part of the HTML documentation.
License
=======
jTDS is released under the terms of the LGPL. A copy of the LGPL is provided
in the LICENSE file.
Thanks
======
jTDS is based on software written by the FreeTDS project that can be found at
http://www.freetds.org/. Much kudos goes to the developers of that software.
Lots of thanks go to SourceForge.net, who in a big part made possible the very
existence of jTDS.
Status
======
Production, Stable.
Stable for concurrent usage (Connections are multithread-safe, Statements are
completely independent). Full support is provided for forward-only and
scrollable/updateable ResultSets, PreparedStatements, and CallableStatements.
A DataSource, a ConnectionPoolDataSource and an experimental XADataSource
implementation are also provided. All of these are implemented by class
net.sourceforge.jtds.jdbcx.JtdsDataSource.
Meta data information is 99.99% complete and accurate (both ResultSetMetaData
and DatabaseMetaData). ParameterMetaData support is partial, some methods
return the same value (which is acceptable, according to the JDBC spec).
jTDS is used in a number of commercial applications. It has been tested with and
is actually recommended as the driver to use for MS SQL Server by pretty much
all open source AND commercial database management tools:
o iSQL-Viewer (http://isql.sourceforge.net)
o SQL Workbench/J (http://www.sql-workbench.net)
o SQuirreL SQL Client (http://squirrel-sql.sourceforge.net)
o Db-Visualizer (http://www.minq.se/products/dbvis/index.html)
o SQL Developer (http://sqldeveloper.solyp.com, really nice tool).
o Artiso Visual Case (http://www.visualcase.com)
There are quite a few database management tools that come bundled together with
jTDS:
o DataDino (http://www.datadino.com/)
o DBInspect (http://www.dbinspect.com/)
o Aqua Data Studio (http://www.aquafold.com/)
o DB Viewer (http://victorpendleton.net/products/dbviewer.html)
For more information about jTDS check out the project's homepage
(http://jtds.sourceforge.net/).
URL Format
==========
Please see the FAQ page for a more detailed explanation of the URL format and
the supported URL properties.
To Do
=====
1. Locator-based Blob/Clob implementation.
2. Minor features, such as failover support.
Contacts
========
jTDS homepage: http://jtds.sourceforge.net/
SourceForge project info: http://sourceforge.net/projects/jtds/
Unit Tests
==========
These are the steps you should follow to run the JUnit tests provided with jTDS
(they are included in the source package, along with some reverse-engineering
tools):
1. Duplicate conf/connection.properties.tmpl as conf/connection.properties.
2. Modify conf/connection.properties to point to your server/database, and put
in your username and password. Most of the tests use only temporary tables, so
almost any user should do (there are a few tests that need to create permanent
tables but they also delete them so you should not end up with garbage in your
database).
3. Set the JAVA_HOME system property to point to your Java installation
location.
4. In a command prompt, type:
build test
This will run a series of JUnit tests on your database. All tests should pass
normally. If any of them fails, please let us know about it (along with the
particular system configuration you were using).
