I want the CFATTVAL value for the max effect date for CFATTRIB PROG for the CTVALUE (ie.1020 for 14224.) This should be simple, right? I can't seem to get all of the CTValues

(Select Max(EFFDT) From [Table1] M WHERE M.CTValue = [Table1]![CTVALUE] ) is where I'm at...not working.

Sorry - had trouble trying to post as a table. all the 1's are the first record in the fields of table1.

This works not sure if it's best though -

SELECT t.CTValue
, t.CFATTRIB
, t.CFATTVAL
, t.EffDt
FROM ( SELECT CTValue
, CFATTRIB
, MAX(EffDt) AS latest
FROM Table1
GROUP
BY CTValue
, CFATTRIB) AS m
INNER
JOIN Table1 AS t
ON t.CTValue = m.CTValue
AND t.CFATTRIB = m.CFATTRIB
AND t.EffDt = m.latest
