| would be better upon compilation, since its entirely valid to create an empty Select object and then append columns to it later. the Query object does it exactly this way.
also, feel free to make all the exceptions pull from a locale-based file, and the error string you propose would be in the "Camelot" locale :). On Jul 24, 2006, at 6:08 PM, Jonathan Ellis wrote: To make it more general, would
if not self._raw_columns:

work in the Select constructor?

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):
