why does this give me the wrong customerNumber?

Question

I tried to get the customer that pay the maximum amount. It gave me the maximum amount but the wrong customer. what should i do?

SELECT temp.customerNumber, MAX         


        

Answer 1

Using a join, possibly as follows:-

SELECT *
FROM payments
INNER JOIN
(
    SELECT MAX(amount) AS MaxAmount
    FROM payments
) Sub1
ON payments.amount = Sub1.MaxAmount

Down side of this is that if 2 people both have the same high payment then both will be returned.
