Mike cleared this up for me in IRC: X.prop.has(<criterion>) just means, exists(select 1 from child where child.id=parent.x_id AND <criterion>) so the more elegant way to do this is session.query(Action).filter(Action.task.has(Task.connection.has(Connection.caller==caller1))) -Jonathan --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
