Any ideas? youd have to attach your full table setup and mappings to have any idea how this error is occuring. id probably classify this as a bug since if your mapping has something SA can't handle, it should be raising a specific error at compile time instaed of randomly failing at query time. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
