There's no functional need for those. For shorter names, other options are: a) just use shorter column names or b) keep the long names as-is in the database but use short names in Python via the key='shortname' option to Column. The latter is a common strategy when you're stuck with a legacy schema. -j --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
