超时已过期.操作完成之前经过的超时时间或服务器没有响应

Question

我不确定这是VB.NET错误还是SQL Server.但我得到以下错误与以下堆栈跟踪:

[SqlException(0x80131904):超时已过期.操作完成之前经过的超时时间或服务器没有响应.]

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,如果我在我的存储过程中做了这个小改动,它会通过,但不会给我我想要的数据:没有错误,但是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, 0, 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_REPORT_DATE,  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', COUNT(DISTINCT A.QXP_EXCEPTION_NO), A.QXP_REPORT_DATE, DATEADD(M, DATEDIFF(M, 0, 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_REPORT_DATE, b.new_modes

Answer 1

您需要在dataadapter的select命令上增加命令超时.

下面是增加dataadapter命令超时的代码.

adapter.SelectCommand.CommandTimeout = 0;

SQL连接超时与为执行的命令设置的超时不同.

它的定义如下.来自MSDN

获取在终止尝试并生成错误之前尝试建立连接时等待的时间.

从MSDN设置连接超时..

您可以使用连接字符串中的ConnectTimeout或Connection Timeout关键字设置连接等待超时的时间.值0表示没有限制,应该在ConnectionString中避免,因为尝试连接无限期等待.

所有超时的默认值为30秒.

Answer 2

通过查询分析器（或现在的 SSMS）获得的结果与应用程序获得的结果可能非常不同，这主要是由于参数嗅探造成的。

我建议阅读Erland Sommarskog 的这篇文章以了解详细信息。
