存储过程性能问题

我有帐单应用程序，它具有一些报告生成功能。运行6-7个月后，我面临有线问题。我的sql语句在管理工作室编辑器中完美运行（4秒执行），但是当我将相同的查询放到SP时，需要（1分9秒执行相同的查询）。表有150K行。下面是我在SP中使用的查询。我的应用程序显示超时过期异常消息。我尝试将连接字符串中的超时设置为180秒。（对于临时解决方案），但没有正面结果。存储过程性能问题

ALTER PROCEDURE [dbo].[rpt_GetShiftEndReport](
@BillDate varchar(10), 
@JobShift int, 
@MonthStartDate varchar(10), 
@MonthEndDate varchar(10) 
) 
AS 
--begin tran 
    SET NOCOUNT ON; 

SELECT  Products.pCode AS ProductCode, MIN(Products.pName) AS ProductName, MIN(Products.pSize) AS ItemSize, MIN(I.gName) AS GroupName, Sales_Trans.Price, 
SUM(Sales_Trans.Sales_Qty) AS SalesQty, SUM(Sales_Trans.Sales_Value) AS SalesValue, SUM(Sales_Trans.Break_Qty) AS BreakQty, 
SUM(Sales_Trans.Break_Value) AS BreakValue, SUM(Sales_Trans.Return_Qty) AS ReturnQty, SUM(Sales_Trans.Return_Value) AS ReturnValue, 
MIN(Products.CloseStock) AS Stock, MIN(Products.pGroup) AS GroupCode, 
dbo.GetCummulativeSales(@MonthStartDate, @MonthEndDate, Products.pCode) AS CummSales 

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;

任何人都可以建议我现在该做什么。我不认为它的查询问题可能不会。的行。

您确定您在SP中的参数与查询中的参数值相同（当您不使用SP时）吗？ – 2011-03-19 17:57:43

是的，我从SP复制了值到查询 – 2011-03-19 17:59:58

抱歉，声音唠叨......但是，有3个varchar（日期）参数。你有没有确保你为每个值传递了合适的（和期望的）值，并且当你使用SP时，这些参数之间的值没有得到交换？对不起，只是检查.. – 2011-03-19 18:03:41
