Hello,
wanting to create the following query:
(SELECT * from tbl ORDER BY b LIMIT 5) UNION ALL (SELECT * from tbl
ORDER BY a LIMIT 5)
The important thing are the (), which I cant get to work with the
examples in the union() docs .
I came across a solution involving self_group on Queries in an old
mailing list post (using SA 0.4)
This is what I figured:
q=session.query(Table)
querylist=[q.order_by(Table.b).limit(5), q.order_by(Table.a).limit(5)]
sel = q.union_all(*[q.self_group() for q in querylist])
But I get an error, that Query has not self_group attribute.
Seems self_group is not longer a Query member. So how would I create a
query like this?
cheers
Sebastian
