[Zope] Sybase connection

Hi all, Is there anyone who uses the Sybase DA? I get the following error : Error, Products.SybaseDAv2.db.Error: Unexpected result type Now, what can the problem be? I assume that this error is caused, because the stored procedure returns a result type unknown to the driver? Is this possible? If so, is there a newer driver which can handle more types? (I using the driver SybaseDA-2.0b2-src.tgz 2.0b2 (Development) 2000/02/03) Thanks for all the possible help, Tom.
