If I got it right, then, as far as I know, two transactions is impossible in one connection and most probably second thread is trying to change something in table that thread one is dealing with. > > Using SQL expressions with ORM transactions is covered in this section > of the docs: > > http://www.sqlalchemy.org/docs/04/session.html#unitofwork_sql > > Hope that helps, Not sure where is appropriate to use SessionContext (which is deprecated), sessionmaker, scoped_session, create_session and stuff.
