The "type" attribute (col.type) is all I'm aware of. I would study the types module (sqlalchemy.types), since col.type will subclass one of those base types. Also, col.type.get_col_spec() may be of interest. An example of a Postgresql text typed column, where t is the table def. >>> t.c.name.type PGText(length=None, convert_unicode=False, assert_unicode=None) >>> t.c.name.type.get_col_spec() 'TEXT' --Randall --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
