If your dealings with data are already framed by a Session, you can work with the SQL expression language in that context using either Session.execute() or work with the Connection that's part of the current transactional scope by calling Session.connection() to get at it. This essentially maintains the usage of Session as your transaction management object, you just aren't using the object-relational aspects of it. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
