This should probably be handled by zope as it is by SQL: the names of the variables become: tablename.columnname (clients.id and columns.id in the example below). No ?

It's up to the DB interface - what does it return in the description of the column. I know it varies from RDBMS to RDBMS. You're safer to just specify it explicitly with 'as foo', anyway. (next time people are considering zope mailing list splits - probably an aqueduct list (or zope-rdbms) would be one to split off... no?) Anthony
