(its a LEFT JOIN...matching rows from the view need not be present). unless, as i suspect, you want the view's columns in the columns clause and not those of "hierarchy" (which is why I asked for the full SQL, which i still dont have here). if this is the case, you want to make a new "non_primary" mapper mapping your class to view, and then create a normal eager load to that mapper. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
