The result set is not doing a group by, it looks more like an order
by. The SQL to produce your specified result set is:
select empid, groupid, crdate
from tablea
order by empid asc, crdate desc

Hi, SQL experts,
Your help on the following qestion will be much appreciated.
For example:
TableA contains:
EmpID GroupID CrDate
22 4 1/20/98
24 3 1/19/98
25 4 1/18/98
25 6 1/17/98
24 5 1/16/98
22 3 1/15/98
how do I get a query output like the following with pure SQL code:
(Group by EmpID and order by the lastest crdate first within each EmpID)
EmpID GroupID CrDate
22 4 1/20/98
22 3 1/15/98
24 3 1/19/98
24 5 1/16/98
25 4 1/18/98
25 6 1/17/98
