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.
Daniel Leighton
