Select Most Recent States From History Table

Question

I have inherited a table with a structure something like this:

ID   Name   Timestamp   Data
----------------------------
1    A      40          ...
2    A               


        

Answer 1

Another easy way :

SELECT ID,Name,Timestamp, Data
FROM   Test_Most_Recent
WHERE Timestamp = (SELECT MAX(Timestamp)
                 FROM Test_Most_Recent
                 group by Name);
