INSTALLING JTDS JDBC DRIVER
When calling a stored procedure that has output parameters, the driver has to call the procedure using a remote procedure call RPC. 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. 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. It means exactly what it says. These benchmarks are free to download so we encourage you to do it and run them yourself. Sign up using Facebook. If you are using Eclipse:

Stored procedures should be invoked using the special JDBC call escape syntax. Because there is no URL when using nistalling 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: Insralling 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. I’m trying to connect to SQL Server 6. Indeed, some SQLExceptions are reported with a correct state code and some not.
The new methods have been “implemented”, but their implementations are all throw mtds AbstractMethodErrorwhich means they can’t actually be used. It is possible to use mixed parameter lists to call stored procedures that do not have output parameters. There are three possible causes to this if we exclude not creating the ResultSet with the appropriate type and concurrency in the first place:.
This parameter is lastUpdateCount and you can find out more about it here. 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: If you’re new to Java, I’d strongly recommend that you learn the basics including the classpath before you start doing insatlling JDBC work.

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 instxlling own drivers. These benchmarks are free to download so we encourage you to do it and run them yourself. Related content No related content found.

The exception you are getting is usually caused by a timeout. The number of statements that are kept open simultaneously can be controlled with the maxStatements parameter; see the jTDS URL format for more information. Sign up or log in Sign up using Google.

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. ClassNotFoundError is thrown by the classloader when it can not find a certain class. inxtalling
In both cases if you call Statement. Microsoft offers a full JDBC4. Or even better, a benchmark I can run myself?
JTDS Driver | Documentation
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. 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.
There is a good side to this: 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.
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. Microsoft’s driver is actively maintained, where jTDS hasn’t been updated since and prior to the small round of updates done in it hadn’t been updated for multiple years. 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.
