Here is what I have:
SELECT Custid, Invoicedate AS Monday_Date,
(SELECT Sum(R_Sales) FROM Order_Header_Invoice AS T2 WHERE
T2.Invoicedate <= T1.Invoicedate AND T2.Invoicedate >= DateAdd(day, -90, T1.Invoicedate) ) AS Sales_L90D
FROM Order_Header_Invoice AS T1 WHERE ( DatePart(weekday, Invoicedate) =
2 AND Invoicedate >= DateAdd(day, -365, getdate()) )
GROUP BY Custid, Invoicedate
ORDER BY Custid, Invoicedate DESC
but I get a "Timeout Expired" error. Is this causing an infinite loop? Received on Wed Jan 14 2009 - 11:05:38 CST
