这是在Microsoft .NET Framework版本：2.0.50727.3620; ASP.NET版本：2.0.50727.3618和SQL Server 2008.
它标记导致此错误的行说：

1: PrintMessageGrid.DataSource = GlobalFunctions.GlobalF.GetComplaintTrendingList6(FirstMonthDate,LastMonthDate,TheLevel)

即使我可以在查询分析器中运行此存储过程,它将在8秒后返回.可能是什么原因和修复？

这里是我声明这个函数的更多细节：

Public Shared Function GetComplaintTrendingList6(ByVal FirstMonth As DateTime,ByVal LastMonth As DateTime,ByVal rowLevel As Integer) As DataSet
    Dim DSPageData As New System.Data.DataSet
    Dim param(2) As SqlClient.SqlParameter

    param(0) = New SqlParameter("@FirstMonthDate",SqlDbType.DateTime)
    param(0).Value = FirstMonth
    param(1) = New SqlParameter("@LastMonthDate",SqlDbType.DateTime)
    param(1).Value = LastMonth
    param(2) = New SqlParameter("@TheLevel",SqlDbType.Int)
    param(2).Value = rowLevel

    ''# A Using block will ensure the .Dispose() method is called for these variables,even if an exception is thrown 
    ''# This is IMPORTANT - not disposing your connections properly can result in an unrespsonsive database 
    Using conn As New SQLConnection(ConfigurationSettings.AppSettings("AMDMetricsDevConnectionString")),_
   cmd As New SQLCommand("ComplaintTrendingList6",conn),_
    da As New SQLDataAdapter(cmd)
        cmd.CommandType = CommandType.StoredProcedure
        cmd.Parameters.AddRange(param)

        da.Fill(DSPageData)
    End Using

    Return DSPageData
End Function

奇怪的是,如果我在存储过程中进行了这么小的改动,它会通过,但不会给我我想要的数据：
没错,但这个版本没有给我我想要的东西：

SELECT E.PRODUCT_GROUP,a.QXP_SHORT_DESC,COUNT(DISTINCT A.QXP_EXCEPTION_NO),A.QXP_REPORT_DATE,DATEADD(M,DATEDIFF(M,A.QXP_REPORT_DATE),0) AS STARTDATE
FROM ALL_COMPLAINTS A
LEFT OUTER JOIN SMARTSOLVE.V_QXP_ISSUE_REF D ON A.QXP_ID = D.IRF_QXP_ID 
INNER JOIN CT_ProductFailures b ON b.old_modes = a.qxp_short_desc
LEFT OUTER JOIN [MANUAL].PRODUCTS E ON A.EPA_PRD_CODE = E.LIST_NUMBER 
LEFT JOIN SMARTSOLVE.V_CXP_CUSTOMER_PXP C ON A.QXP_ID = C.QXP_ID
INNER JOIN @SelectedLevels F ON A.[LEVEL] = F.LevelId
WHERE   --[LEVEL] > 0 AND
(A.QXP_SHORT_DESC <> 'Design Control') 
and A.QXP_REPORT_DATE >= @OneYearAgo AND A.QXP_REPORT_DATE <= @LastMonthDate
AND (C.QXP_EXCEPTION_TYPE <> 'Non-Diagnostic' OR C.QXP_EXCEPTION_TYPE IS NULL)  
GROUP BY E.PRODUCT_GROUP,A.QXP_SHORT_DESC

导致错误的存储过程：

INSERT #PVAL_NUM
SELECT E.PRODUCT_GROUP,b.new_modes 'QXP_SHORT_DESC',0) AS STARTDATE
FROM ALL_COMPLAINTS A
LEFT OUTER JOIN SMARTSOLVE.V_QXP_ISSUE_REF D ON A.QXP_ID = D.IRF_QXP_ID
