をCREATEその他のフィールドに

をもたらしますその後、達成することができます次の簡単な選択クエリを使用してください：

CREATE PROC GET_ORDER_ACCOUNT_DETAILS 
@ORDERID INT 
AS 
BEGIN 
SET NOCOUNT ON; 

    SELECT 
      CASE 
       WHEN od.calcType = 'K' 
       THEN od.price * od.kilo 
       ELSE od.quant * od.price 
      END   as [AMOUNT] 
     ,od.quant  as [QUANTITY] 
     ,od.kilo  as [KILO] 
     ,od.price  as [PRICE] 
     ,od.calcType as [UNIT] 
     ,p.prodName as [NAME] 
     ,od.recivedID as [RECIVED] 
    FROM  orderAccTBL  oa 
    INNER JOIN orderDetailsTBL od ON od.orderID = oa.orderID 
    INNER JOIN productTBL  p ON p.prodID = od.productID 
    WHERE oa.orderID = @ORDERID 

END
