Here productCode 10001 contain 2 records when I run query it return 2 reords.I want to get only one records.

 SELECT     WMProduct.BusinessUnit, WMProduct.ProductCode, StockRecord.Name, WMPriceDetail.Price
 FROM       WMProduct INNER JOIN StockRecord
            ON WMProduct.ProductCode = StockRecord.ProductCode
           INNER JOIN WMPriceDetail
            WMPriceDetail ON WMProduct.BusinessUnit = WMPriceDetail.BusinessUnit AND WMPriceDetail.ProductCode = WMProduct.ProductCode

 WHERE     (WMPriceDetail.DateFrom < GETDATE()) AND (WMPriceDetail.DateTo > GETDATE() OR
            WMPriceDetail.DateTo = NULL)

This query returns

   BusinessUnit ProductCode     Name   Price
     ORB         10001         SunSilk    12.00
     ORB         10001         SunSilk    21.00

But I need only one records….
BusinessUnit ProductCode Name Price
ORB 10001 SunSilk 21.00
ORB 10002 Pen 54.00

From that query i can’t put TOP 1 because there are more table combine.. join

If the price is not define in the price detail table, that records should not show into the list.

Please help me….

Thanks in advance

Try this friend:

 select p.businessunit, p.productcode, pr.price from
 WMProduct p ,WMStockRecord s, WMPriceDetail pr
 where p.productcode = s.productcode and
    s.productcode = pr.productcode and p.productcode=pr.productcode and
    pr.datefrom = (select max(datefrom) from WMPriceDetail where productcode = p.productcode  and
  (
    ( DateFrom < 'Sep 06 2011') AND (DateTo > 'Sep 06 2011' OR DateTo IS NULL) 
  )
