Although queries returning multiple results are not very common, it is the reason why this behavior is customizable from the URL. But I confused what should be written in Class. If that’s the case, replace jtds. Or even better, a benchmark I can run myself? Temporary stored procedures are created for each unique SQL statement and parameter combination faster.

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. 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.
Batch processing using executeBatch hangs or is unreliable on Sybase.
The default install does not configure the SQL Browser service to start automatically so you must do it manually. But I confused what should be written in Class. This gives jTDS a 2x performance increase over the next fastest driver in some not so uncommon cases. If that’s the case, replace jtds.
