Question

This is my SQL statement that works using datediff:

SELECT SUM(b134_nettpay) AS Total, b134_rmcid, b134_recdate  FROM  B134HREC  WHERE datediff (dd, '2006-05-05', getdate()) > 90 GROUP BY b134_rmcid, b134_recdate  ORDER BY b134_recdate DESC, b134_rmcid 

I need to Replace the Hardcoded date ‘2006-05-05’ with MAX(b134_recdate) like so:

SELECT SUM(b134_nettpay) AS Total, b134_rmcid, b134_recdate  FROM  B134HREC  where datediff (dd, MAX(b134_recdate), getdate()) > 90 GROUP BY b134_rmcid, b134_recdate  ORDER BY b134_recdate DESC, b134_rmcid 

But i get this Error message:

An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference.

Any idea how to fix my SQL Statement?

Try

SELECT SUM(b134_nettpay) AS Total, b134_rmcid, b134_recdate  FROM  B134HRE  where datediff (dd,        (select MAX(b134_recdate) from B134HRE)       , getdate()) > 90 GROUP BY b134_rmcid, b134_recdate  ORDER BY b134_recdate DESC, b134_rmcid
