But do I do this? Part of the problem is that I don't know of a way

Hello Group,
I see the following behaviour which I can not explain (don't know
sqlalchemy too well though):
I have the following table setup (heavily simplified):
class WikiPage(Base):
__tablename__ = 'wiki_page'
id = Column(Integer, primary_key=True)
name = Column(Unicode(40))
Hi,
I'm trying to translate this sql expression:
(select max(id) as max_id from votes group by user_id, idea_id) as m
left join votes on m.max_id=votes.id
Into python code. So far I have:
s = Session()
q =
s.query(sa.func.max_(Vote.id).label('max_id')).group_by(Vote.idea_id,
Vote.user_id)

which two names/functions are you referring to ?

OK, just in case anyone else is foolishly trying to run SQLA on ironpython,
here's the workaround I've found:
instead of attempting to use the mapper directly on the join:
j = join(movies_table,md_table).join(directors_table)
mapper(MoviesAndDirectors,j) #ipy errors here
use a mapper on a
