[Zope] What can I do with a Results instance from a mysql query?

Hi all, Getting better at this Zope thing, but I still have problems. I want to retrieve data from a mysql database, store it in the session, and then return a page template that makes use of that data. This is all from within a python script. The problem I'm having is it doesn't like storing an entire results instance into the session. I don't want to create a dictionary and go through the fields one by one, but is there an equivalent of keys() for the Results object? Thanks very much, Alec Munro
