I\'m sure this is a pretty simple SQL query question, but I\'m sure there\'s a good way, and a very BAD way, to do this. Left to my own devices, I\'m liable to end
SELECT t1.*
FROM (SELECT Table1.ID, Max(Table1.As_Of) AS MaxOfAs_Of
FROM Table1
GROUP BY Table1.ID
) AS MaxIDS INNER JOIN Table1 t1 ON MaxIDS.ID = t1.ID
and MaxIDS.MaxOfAs_Of = t1.As_Of
