why not try something like: ualias = aliased(User, table_2012) query(ualias).filter(ualias.x == 1) or: query(User).select_from(table_2012) something like that. it can’t be 100% transparent, the query needs to be told that its selecting from something different. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
