you'd say, s.alias().select()
it makes subqueries which MySQL probably doesn't require.

Hi all,
There appear to be some nuances to using order by statements with set
operations like unions in MySQL but the following is allowed*:
(SELECT a,b from DBA.tbl ORDER BY b LIMIT 5)
UNION ALL
Thanks for the quick response!
The following does *not* work. Am I making the call incorrectly?
sel = union_all(*[q.self_group() for q in querylist])

I had to upgrade to 0.4.7 from 0.4.2, but your sample query works,
however, my application of it does not.
Sorry I'm being so light on details, I'll try to reproduce with a
complete sample versus using snippets of production code.
Each select statement is generated like so:
sel =
there's logic which is removing the order_by's from the selects, and
in that case this is what's blowing away the parenthesis as well.
Some databases don't even allow ORDER BY inside of the queries used in
a UNION since in the absense of LIMIT/OFFSET, which also is not
standard SQL,
