For this, you need a derived table:
select
from Payments p
join
(
select CustomerNo
, Date = max (Date)
from Payments
group by CustomerNo
) as x on x.CustomerNo = p.CustomerNo and p.Date = x.Date

There is a table called "Payments" which records every payment that a
company has received:
CustomerNo Date Amount
----------------------------------------
3214 2/12 30
3214 4/10 50
9943 4/18 40
9943 5/10 30
9943 2/13 70
1121 5/23 10
1121 4/20 40
1121 3/12 30
(more data...)
I want to be able to pull out the last payment made by everyone in a query:
CustomerNo Date Amount
---------------------------------------
3214 4/10 50
9943 5/10 30
1121 5/23 10
(other users...)
How should I write the SQL statement? Please email to me at
