thats an invalid query - the "signals" table is not in the FROM condition. also your code below seems to indicate you want the outer query to join on "module_inputs" but up here you put "module_outputs" in your main FROM clause. construct your SQL query as plain text, run it and make sure it returns what you want, then send it back here if youre still stumped. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
