Joost --
You are correct in stating that the problem is that the subquery returns more than 1 row -- try using the NOT IN syntax ... it is not likely to be very efficient but at least avoids the syntax error:
select order_id from order, orderline
where order_id = parent_order_id
and order_price NOT IN (select sum(orderline_price) from orderline group by
parent_order_id)

Subject: [SQL] Help with simple SQL query?
Hi,
I have 2 tables with the following columns:
order: order_id, order_price
orderline: parent_order_id, orderline_price
I want all orders order where _price <> sum(orderline_price).
What is wrong with the following query:
select order_id from order, orderline
where order_id = parent_order_id
and order_price <> (select sum(orderline_price) from orderline group by
parent_order_id)
It reports "ERROR: more than one row returned by a subquery used as an
expression" which seems right (the select sum() returns multiple rows?),
but I cannot get query right. Can someone help?
TIA
