With the backrefs set up the following worked just as you suggested: >>> q = session.query(Keyword) >>> q.select(and_(q.join_to('section'), section_table.c.name=='Health')) [2006-10-07 18:57:19,519] [engine]: SELECT keyword.name AS keyword_name, ... FROM keyword, item_keyword, item, section WHERE ((keyword.uuid = item_keyword.keyword_uuid AND item.uuid = item_keyword.item_uuid) AND section.id = item.section_id) AND section.name = ? ORDER BY keyword.oid [2006-10-07 18:57:19,519] [engine]: ['Health'] Thanks much. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
