What is "th.query()" ?
Since the session is bound to the mapped classes(in tg and in sa). I shouldn't have to use session.query(mymappedclass).somfilter What I want to do is convert the: session.query(th).filter(sqlalchemy.and_(th.APPLIED_TEST==1,th.CODING_DATE=='20080325')).all() to just a query using mapped class. Asumed that session.query(th).somefilter is same as th.query().somefilter would do it, but obviously these two are different. So I my question is, are the session.query(th).somefilter vs th.query().somefilter different or am I missing something here.
