Hi I have this table with 3 columns.. What I want is
Distinct(record_id),max(due_date) and Status.. I tried this
select distinct(record_id),status,(due_date) from table1 where
(due_date) in
(select max(due_date) from table1 as A where a.record_id=record_id
and a.due_date is not null group by a.record_id,status)

So the result that I want is

Record Status Max(due_date)

I think this may be what you want. I'll assume that the primary key is
(record_id, due_date).

SELECT record_id, status, due_date
FROM Table1 AS T
WHERE due_date =
(SELECT MAX(due_date)
FROM Table1
WHERE record_id = T.record_id)
