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

I don't think you need the Subquery here:

SELECT p.customerNumber, MAX(p.amount) AS max
FROM payments p
GROUP BY p.customerNumber
ORDER BY max DESC
LIMIT 1
