Select the largest amount from a field in SQL Server 2000 Table

Hi all.

I have a SQL Server 2000 table (myTable) that has the following fields:

ItemNumber---Qty---Date

How do I select the largest Qty for each itemnumber from the previous month.

So let's say I have item: 123
Qty: 10--Date: 01/01/2011
Qty: 5--Date: 01/02/2011
Qty: 75--Date: 02/02/2011
Qty: 35--Date: 03/01/2011
Qty: 20--Date: 03/02/2011
Qty: 50--Date: 03/03/2011

The result should be 50 because I want the largest QTY amount from the PREVIOUS month.

Thank you in advance!

like this.
SELECT ItemNumber, 
         MAX(Qty) AS max_Qty 
    FROM myTable 
   WHERE DATEPART(MM,GETDATE()) - 1 = DATEPART(MM,[Date]) 
GROUP BY ItemNumber
