Subqueries
I have four tables (Customer, OrderTbl, OrdLine and Product). I have to list the customer number of customers who have ordered all of the products that a manufacture called ColorCorp have to offer.
describe customer;
CUSTNO
describe product;
PRODNO
PRODMANUFACTURE
describe ordertbl
ORDNO
CUSTNO
describe ordline
ORDNO
PRODNO
I tried very unsuccessfully using subqueries. I just can’t manage to get it going. Can anyone please give me any adivice or help, very much appreciated.
