存儲過程性能問題

我有帳單應用程序，它具有一些報告生成功能。運行6-7個月後，我面臨有線問題。我的sql語句在管理工作室編輯器中完美運行（4秒執行），但是當我將相同的查詢放到SP時，需要（1分9秒執行相同的查詢）。表有150K行。下面是我在SP中使用的查詢。我的應用程序顯示超時過期異常消息。我嘗試將連接字符串中的超時設置爲180秒。（對於臨時解決方案），但沒有正面結果。存儲過程性能問題

ALTER PROCEDURE [dbo].[rpt_GetShiftEndReport](

    SET NOCOUNT ON;

FROM   Products INNER JOIN 
(SELECT  SalesLog_1.ProductCode, SalesLog_1.Price, SalesLog_1.Quantity AS Sales_Qty, SalesLog_1.Price * SalesLog_1.Quantity AS Sales_Value, 
0 AS Break_Qty, 0 AS Break_Value, 0 AS Return_Qty, 0 AS Return_Value 
FROM   SalesLog AS SalesLog_1 INNER JOIN 
Sales ON SalesLog_1.MemoNo = Sales.MemoNo 
WHERE  (SalesLog_1.BillDate = @BillDate) AND (Sales.JobShift = @JobShift) 
UNION ALL 
SELECT  ProductCode, Price, 0 AS Sales_Qty, 0 AS Sales_Value, 0 AS Break_Qty, 0 AS Break_Value, Quantity AS Return_Qty, 
Price * Quantity AS Return_Value 
FROM   SalesReturn 
WHERE  (BillDate = @BillDate) AND (JobShift = @JobShift) 
UNION ALL 
SELECT  ProductCode, Price, 0 AS Sales_Qty, 0 AS Sales_Value, Quantity AS Break_Qty, Price * Quantity AS Break_Value, 0 AS Return_Qty, 
0 AS Return_Value 
FROM   Breakages 
WHERE  (BillDate = @BillDate) AND (JobShift = @JobShift)) AS Sales_Trans ON Products.pCode = Sales_Trans.ProductCode INNER JOIN 
ItemGroup AS I ON I.gCode = Products.pGroup 
GROUP BY Products.pCode, Sales_Trans.Price 
ORDER BY GroupCode, ItemSize DESC;

任何人都可以建議我現在該做什麼。我不認爲它的查詢問題可能不會。的行。

您確定您在SP中的參數與查詢中的參數值相同（當您不使用SP時）嗎？ – 2011-03-19 17:57:43

是的，我從SP複製了值到查詢 – 2011-03-19 17:59:58

抱歉，聲音嘮叨......但是，有3個varchar（日期）參數。你有沒有確保你爲每個值傳遞了合適的（和期望的）值，並且當你使用SP時，這些參數之間的值沒有得到交換？對不起，只是檢查.. – 2011-03-19 18:03:41
