Hi all ,

I have three tables:
OITM (ItemCode,Name),
OITW (ItemCode,WareHouseCode,StockHand,OrderQty),
WITM (ItemCode,LastUStock)

Now I want to join the three tables and I want to select he values of ItemCode and sum(StockHand - OrderQty) grouped by ItemCode where the sum(StockHand - OrderQty) <> LastUStock. How to get this value using join query?

SQL

Select OITM.ItemCode,sum(StockHand - OrderQty) from OITM  inner join WITM on OITM.ItemCode= WITM.ItemCode inner join OITW on OITM.ItemCode =OITW.ItemCode and OITW.WareHouseCode in ('WH1','WH2','WH4')  Group by OITM.ItemCode Having sum(StockHand - OrderQty) <> WITM.LastUStock

please help any one

Thanks

Try modifying the query. The following line should not be a part of the join structure itself, but rather a filter for the join structure:

SQL

OITW.WareHouseCode in ('WH1','WH2','WH4')

Put it in as a WHERE clause:

SQL

SELECT
   OITM.ItemCode,
   sum(StockHand - OrderQty) AS NetStockHand
FROM
   OITM inner join 
   WITM on OITM.ItemCode = WITM.ItemCode inner join 
   OITW on OITM.ItemCode = OITW.ItemCode 
WHERE 
   OITW.WareHouseCode in ('WH1','WH2','WH4')
GROUP BY 
   OITM.ItemCode 
HAVING
   sum(StockHand - OrderQty) <> WITM.LastUStock
