A few things I've run into that might help:

1. To get this working I had to use DBD::Sybase 0.91, not the latest version. I was using FreeTDS 0.53, haven't tried this with 0.60.

2. That configuration does not support bind parameters at all. You have to do the 'bad thing' and build your query string outside the DBD call. Hopefully FreeTDS 0.60 supports the newer version of DBD::Sybase that supports bind parameters. I'm hoping to get a chance to play with it next month.

3. Microsoft SQL Server stored procedures can return multiple result sets from a single call, and support for this is iffy. Try testing with a stored procedure that you know will only return one result set.

Good Luck!
