在执行当前Web请求期间生成了未处理的异常.可以使用下面的异常堆栈跟踪来识别有关异常的起源和位置的信息.

这是我从.NET应用程序调用的存储过程的源代码.

USE [TCO]
GO
      ALTER PROC [dbo].[SP_TCOV3] (@year INT) AS
DECLARE @rpt_year INT;
IF @year > 2011 
BEGIN
SET @rpt_year = 2011;
END
ELSE
BEGIN   
SET @rpt_year = @year;
END
DECLARE @From_Date DATETIME='01-01-2012'  -- mm/dd/yyyy
DECLARE @End_Date DATETIME=(SELECT TOP 1 DATEADD(dd,-DAY(DATEADD(m,1,dbo.ManpowerCost.payment_date)),DATEADD(m,dbo.ManpowerCost.payment_date)) as value
FROM dbo.ManpowerCost order by payment_date desc)

FROM
        --dbo.FN_TCOV3(@rpt_year)AS allApps 
        dbo.FN_TCOV3_Report(@From_Date,@End_Date)AS allApps 

)ORDER BY allApps.[Application Name]

如果我不使用上面使用的开始日期和结束日期参数,那么相同的proc工作正常
并调用dbo.FN_TCOV3(@rpt_year)AS allApps而不是dbo.FN_TCOV3_Report(@ From_Date,@ End_Date)AS allApps,唯一的差异. b / w这两个函数是一个只用一年作为参数而另一个作为2个参数即开始和结束日期.

我需要使用这两个参数,请协助.
