I created a testcase here - https://gist.github.com/jvanasco/a2ff04614a23e192ac7f this has been stumping me this morning. the sql I want is: update table_a set id_b__latest = ( :other_query ) generated from something like: s.execute(TableA.__table__ .update() .values(id_b__latest=_q_sub) ) other_query is a `session.query(TableB)...limit(1)` if other_query is a .subquery() , the generated SQL is "id_b__latest=SELECT" -- which fails because of no parenthesis if other_query is a .select() or .subquery().select(), then we get an intermediate query "id_b__latest=(SELECT anon_1.id FROM (SELECT table_b.id" does anyone know how I can get the parens without the wrapped intermediate query?
did you try as_scalar() on that subquery? that's usually the best. if it doesn't work I'll go through the test case.
