[Zope-dev] Multiple Database Connections Same Zsql method

Is it possible to iterate though multiple databases with the same zsql method? Have multple identical databases with different data. Want to maintain only one method. Can i do this in DTML or do I have to use pythonscripts? I guess what I want to do is to have the query in one folder, call it from another folder and pass the database connection info to it. Not sure how well this would work with multiple users though....... Any advice is appreciated.
