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. 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. As a conclusion the only safe multithreading scenarios are these: 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. See an example here, on GitHub.

A common mistake is to append a semicolon “;” to the end of the URL e. 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.
Have you got any figures to prove that? Masql even better, a benchmark I can run myself?
The exact values to use in the new URL are beyond the scope of this documentation; they must be chosen based on the jTDS settings they are replacing.
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.
These benchmarks are free to download so we encourage you to do it and run them yourself. Of course, we will keep offering support on our SourceForge forums just as we did until now. If you are getting this in an application, start your application with.
You are very probably using TDS 4. The “Connection refused” exception is thrown by jTDS when it is unable to connect to the server. This gives jTDS a 2x performance increase over the next fastest driver in some not so uncommon cases.
Batch processing with executeBatch hangs or is unreliable on Sybase. We will make the necessary changes. The number of statements that are kept open simultaneously can be controlled with the maxStatements parameter; see the jTDS URL format for more mssql.
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. Can jTDS be used in a multi threaded application? While you are msql getConnection function -You can do that by adding name of your database in front of the server name in the connection string.

While doing this it times out, throwing the exception you see which means that jTDS was not able to get smsql about the running instances. SQL is sent to the server jtrs time without any preparation, literals are inserted in the SQL slower.
In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers? 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. In the Bitbucket Server home directorykssql. 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.
In our oppinion this is better than having a benchmark of our own, which could be mtds in such a way as to give jTDS the edge. 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.
Features such as generated keys retrieval, named stored procedure parameters, and save points are also implemented. The JNetDirect license precludes publication of performance test results. When calling a stored procedure that has output parameters, the driver has to call the procedure using a remote procedure call RPC.
