Re: [Sqlalchemy-users] more things you thought nobody would do with Joins

the select(use_labels=True, from_obj=[j]) has no columns in it: str(select(use_labels=True, from_obj=[j])) SELECT  FROM users JOIN email_addresses ON users.user_id = email_addresses.user_id you probably want:             s = j.select(use_labels=True).alias('foo') On Jul 21, 2006, at 10:21 PM, Jonathan Ellis wrote: def testjoinwithlabels(self):         class UserWithAddress(object):             pass         j = join(users, addresses)         s = select(use_labels=True, from_obj=[j]).alias('foo')          m = mapper(UserWithAddress, s)         q = create_session().query(m)
