[Zope] is it possible to bypass ZSQL methods and call stored procedures in sqlserver straight from ZPT?

Hi We have some dynamic ZSQL methods all working but are looking to optimise our code and also access some stored procedures which are already written in SQL Server. The question is, can you go straight through to a relational database using the connector object and call a stored procedure straight from a ZPT? Or must you use a ZSQL method to access the procedure? Thanks -- michael
