Michael,
do you mean, that subqueries could not be wrapped into sqlalchemy?
what should be the arguments to join() I failed to figure out? how do
I reference different instances of seq in fileter() after?
Thanks,

you talked about mapping to a select statement. mapping means this:
m = mapper(MyClass, someselectable)
mapping like the above is usually done against individual tables, and
usually once per class per
I really want to get a clear vision.
So, I have a table x and mapped class X.
I can use query(X) for simple queries, can I query(X) for structured
ones like
SELECT * FROM x WHERE x.a IN (SELECT )
?
Same about multi-cartesian product can I use query(X).join()
for SELECT * FROM x JOIN x
I meant SELECT x.* FROM x JOIN x AS x1 JOIN x AS x2 ... WHERE
