I am having a complete brain fart on this one. I have 2 tables and there is an ID to link them. One of the fields in table B is a calculated value. Table B is also an archive table so data just gets appended to it and there is a CalculatedDate. I was thinking I would use Max function on calculated date but then I found out that a person's calculated value may not be done each month.

Example

TableA
ID
1
2
3


TableB
ID CalcValue CalcDate
1 1234 4/30/2013
1 1211 5/31/2013
2 9999 5/31/2013
3 7777 3/31/2013
3 6666 4/30/2013


So for my results I would want:

ID CalcValue
1 1211
2 9999
3 6666

SELECT ID,CalcValue
FROM 
(
SELECT ROW_NUMBER() OVER (PARTITION BY ID ORDER BY CalcDate DESC) AS Seq, * 
FROM TableB
)t
WHERE Seq=1
