I didn't read this thread from the beginning, but if you are using TG, probably you are using SA <= 0.3.10, which means you don't have generative select() constructs... So you'll need to modify your code to (not tested): s2=sqlalchemy.select([User.c.YEAR], group_by=[User.c.YEAR]) s3=s2.execute() Cheers, Roger --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
