Say, remove the "x=1" from the above query. neither 0.3 or 0.4 can do that, and this is basically because you don't need to. in 0.4 just hold onto the previous select() which doesn't have the filter. If you're building from a web form, you'd be translating form state into a newly built select() each time so i dont see any use case for removing components there. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
