Problem 6
What’s wrong with this query?
SELECT O.Order_ID,
O.Order_Date, C.Name Customer, L.Type, L.Cost, L.Quantity Qty, I.Name Item
FROM
Orders O, Order_Lines L, Items I, Customers C
WHERE O.Customer_ID =
:B1
AND L.Order_ID =
O.Order_ID
AND I.Item_ID(+) =
L.Item_ID
AND
NVL(I.Org_ID,:B2) = :B2
AND C.Customer_ID =
O.Customer_ID;
