Here's a bit of business that is baffling me, and probably shouldn't. My
table looks like this: 

 

account

customer

sale_amount

 

Each account has multiple customers, and each customer has multiple sales. I
want to get the top 20 customers for each account.

 

If I simply do "GROUP BY account, customer LIMIT 20", I'll get the first 20
customers for the first account. If I try "GROUP BY account, customer ORDER
BY SUM(sale_amount) DESC LIMIT 20", I'll get the top 20 customers.

 

What am I missing?

 

Regards,
