Comments on: 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. http://www.sql-server-performance.com/2007/aggregate-may-not-appear-in-where-clause/ SQL Server Performance Tuning Fri, 17 May 2013 13:31:24 +0000 hourly 1 http://wordpress.org/?v=3.5.1 By: Vignesh http://www.sql-server-performance.com/2007/aggregate-may-not-appear-in-where-clause/#comment-2634 Vignesh Sun, 09 Dec 2012 03:52:57 +0000 http://www.sql-server-performance.com/?=1213#comment-2634 It depends on the situation – for this, it looks like you want “ALL”, so probably a simple where clause, so something like :

SELECT *
FROM Northwind.dbo.Orders
WHERE OrderDate < GETDATE()

Change: I removed the "MAX"

If that does not do it for you, and you have a particular column you need, using a GROUP BY Clause would work in some, "Having" would work in others.
