Question

Lets say I have a table e.g

Request No. Type  Status  
---------------------------
1           New   Renewed 

and then another table

Action ID Request No  LastUpdated    
------------------------------------
1           1         06-10-2010
2           1         07-14-2010
3           1         09-30-2010

How can I join the second table with the first table but only get the latest record from the second table(e.g Last Updated DESC)

Answer 1

SELECT T1.RequestNo     ,
       T1.Type ,
       T1.Status,
       T2.ActionId      ,
       T2.LastUpdated
FROM   TABLE1 T1
       JOIN TABLE2 T2
       ON     T1.RequestNo = T2.RequestNo
WHERE  NOT EXISTS
       (SELECT *
       FROM    TABLE2 T2B
       WHERE   T2B.RequestNo   = T2.RequestNo
       AND     T2B.LastUpdated > T2.LastUpdated
       )
