I have been unable to call Sybase stored procedures from zxJDBC. 
Calls to callproc() always return None and I get a DatabaseError of "no results" when I subsequently call fetchone() or fetchall(). This is true both for procs with and without parameters. Raw SQL strings called via execute() seem to work fine, however. Please see below for a sample function to reproduce the error.

This is the Sybase version string:
Adaptive Server Enterprise/12.5.4/EBF 16128 ESD#9/P/Sun_svr4/OS 5.8/ase1254/2143/64-bit/FBO/Thu Feb  5 02:50:34 2009

I briefly checked the zxJDBC test module in the Jython source and it seems that the code has only been tested against Oracle & MS SQL Server.
I guess that it must be difficult to test all possible database platforms, so I would be happy to do a little beta testing against ASE 12.5.4 if it would help... ;)

Kind Regards,

I forgot to add the Jython version string:
java1.5.0_04 2.5.1 (Release_2_5_1:6813, Sep 26 2009, 13:47:54)

Presumably this would also impact MS SQLServer, so we should look at that too.

Is this functionality available under jyjdbc?

We are going to be replacing zxJDBC with jyjdbc for beta 4, so this may help (get this bug fixed for free). At the very least, it will make it possible to fix, because we are reluctant to touch zxJDBC without strong testing.
