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?
