Question

i am working on a query which joins several tables.here’s the code.
the query works fine until the time i add the third line SUM(SaleItems_T.qtymajor) AS sales. i get an error message which says
Unknown column ‘SaleItems_T.qtymajor’ in ‘field list’
I am trying to build an reorder worksheet.Help is much appreciated.

SELECT ProductMaster_T.ProductName_VC AS PGroup, 
StockMain_T.ItemDescription AS Item,
SUM(SaleItems_T.qtymajor) AS sales,
stockbuffers_T.buffer_qty AS BufferQty, 
(stkbalance_T.AJ1+stkbalance_T.AR2+stkbalance_T.AD3+stkbalance_T.DX4) AS Stock, 
(stkbalance_T.AJ1+stkbalance_T.AR2+stkbalance_T.AD3+stkbalance_T.DX4)-stockbuffers_T.buffer_qty AS Result
FROM ProductMaster_T, StockMain_T, stockbuffers_T, stkbalance_T
WHERE StockMain_T.ItemCode = stockbuffers_T.itemcode 
AND
StockMain_T.ItemCode = stkbalance_T.itemid
AND
ProductMaster_T.ProductID = StockMain_T.ProdID
AND
SaleItems_T.ItemID = StockMain_T.ItemCode
ORDER BY
ProductName_VC,ItemDescription ASC

You haven’t referenced the SaleItems_T table in your query, either in the FROM clause, or through a JOIN.
