Open source JDBC type 4 driver for Microsoft SQL Server ( up to ) and Sybase ASE. jTDS is a complete implementation of the JDBC spec. We also test with the JDBC drivers for Microsoft SQL Server listed on this page. jTDS is an open source % pure Java (type 4) JDBC driver for Microsoft. This page describes how to change from using jTDS to using the Microsoft SQL Server JDBC driver to access Microsoft SQL Server.

I hope this clarifies some of the confusion emanating from the errors above. Back Next. Choose the download you want. 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 features a simple interface with many customizable options:. Job Title.

There may be a number of reasons why this could happen:. 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: 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. The exception you are getting is usually caused by a timeout. 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. The default install does not configure the SQL Browser service to start automatically so you must do it manually.

Why do I still need to provide a username and password? This means among other things that it cannot access platform-specific features, such as determining the currently logged user and his credentials.

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: 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.

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. 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.

There are three possible causes to this if we exclude not creating the ResultSet with the appropriate type and concurrency in the first place:.

In both cases if you call Statement. Also, please take a look at our ResultSet support page for some additional information and tips. 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 'S', respectively ''.

This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions.

We will make the necessary changes. 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. CallableStatement output parameter getter throws java. 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: 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 ResultSet s you will have to loop, consuming all results before reading the output parameters i.

In case you are wondering if this is right, this is a quote from the CallableStatement API documentation: 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. 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.

This parameter is lastUpdateCount and you can find out more about it here. 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.

JTDS Driver | ReadyAPI Documentation

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. In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers? 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 keeps increasing when using generated PreparedStatements. Normally, with a JDBC driver, PreparedStatement s are precompiled on creation, which gives increased performance if they are used a sufficient number of times.

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. I'm trying to connect to SQL Server 6.
