I run out of memory when trying to run a query
I need help with a query. I am trying to extract Total Qty Sold ( and eventually get this data by month), but when I would run the query asking for QTY I get "System Out Of Memory". I removed that party of the query asking for Qty and posted what I came up with below. Any Help is greatly appreciated.
SELECT T0.[ItemCode], T0.[ItemName], T1.[FirmName], T0.[CardCode], T0.[SuppCatNum], T2.[ItmsGrpNam], T0.[U_U_CMG_PROGRAM], T0.[U_U_CMG_CATEG], T0.[U_CMG_STATUS], T0.[U_CMG_STORES], T0.[U_CMG_COLOR], T0.[U_CMG_LOCAT], T0.[MinLevel], T0.[MinOrdrQty]
FROM OITM T0 INNER JOIN OMRC T1 ON T0.FirmCode = T1.FirmCode INNER JOIN OITB T2 ON T0.ItmsGrpCod = T2.ItmsGrpCod
