[Zope-dev] Calling SQL methods in external methods with passed parameters?

HI, I want to call a Z SQL method in an external method and pass to it the relevant parameters. Any clever hints on how to do so? I was under the impression that something akin to rendering DTML pages might work. So I tried: REQUEST.form['level_id']=10 sqlvals = sqlcall(sqlcall,REQUEST) And I'm getting empty data back. Am I missing a field in the request?
