Hi, Is it possible to update a field with the result of a select. For example:
UPDATE ordr_order SET balance = ('SELECT ordr_order.total_cost - sum(ordr_payment.amount) FROM ordr_order LEFT JOIN ordr_payment on ordr_payment.ordr_order_id = ordr_order.id WHERE ordr_order.id = 1') WHERE id = 1 When I execute this query, I don't get an error, but it also doesn't update the field in question. If I execute each query separately, they each work fine. Thanks for your help.
