Yes, those are called subqueries; they're fully supported by SA. Your query above has a couple of items of note:
a) it's a correlated subquery: the inner query references items in the outer query. (supported by SA) b) it's a self-join: the inner query and outer query reference the same table. (also supported by SA) your query roughly translates into: p2 = p.alias() select([p.c.id], p.c.number == select(func.max(p2.c.number), p2.c.attribute == p.attribute)) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
