Actually I can't see how that would work, if SA can't figure out the forwards facing one I don't think it would be that great for it to try guessing the backwards facing one. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
