sql-server - 特定数据库上的DataAdapter.fill(dataset)超时异常

在VB.NET应用程序(VS2005)中，我正在通过SQLDataAdapter调用存储过程。
在我的本地数据库上，一切正常。如果我在另一个数据库上执行此操作，则会收到超时异常。
这是代码:

  Public Overloads Shared Function ExecuteDataset( _
                                                    ByVal connection As SqlConnection, _
                                                    ByVal commandType As CommandType, _
                                                    ByVal commandText As String, _
                                                    ByVal ParamArray commandParameters() As SqlParameter) As DataSet
        If (connection Is Nothing) Then Throw New ArgumentNullException("connection")
        ' Create a command and prepare it for execution
        Dim cmd As New SqlCommand
        Dim ds As New DataSet
        Dim dataAdatpter As SqlDataAdapter
        Dim mustCloseConnection As Boolean = False

        dataAdatpter = Nothing

        PrepareCommand(cmd, connection, CType(Nothing, SqlTransaction), commandType, commandText, commandParameters, mustCloseConnection)
        cmd.CommandTimeout = 0 'I get a timeout exception if I leave this out
        Try
            ' Create the DataAdapter & DataSet
            dataAdatpter = New SqlDataAdapter(cmd)

            ' Fill the DataSet using default values for DataTable names, etc
            dataAdatpter.Fill(ds)

            ' Detach the SqlParameters from the command object, so they can be used again
            cmd.Parameters.Clear()
        Finally
            If (Not dataAdatpter Is Nothing) Then dataAdatpter.Dispose()
        End Try
        If (mustCloseConnection) Then connection.Close()

        ' Return the dataset
        Return ds
    End Function ' ExecuteDataset

我已经直接在数据库上执行了存储过程，并且工作正常且快速。
我还尝试将cmd的CommandTimeout属性设置为0。
当我这样做时，将执行存储过程，但这需要很长时间。
同样，如果我在本地数据库上工作，则没有问题。

这是超时异常的堆栈跟踪

关于这可能是什么原因的任何想法？

最佳答案

我找到了解决方案。

事实证明这是查询优化的参数嗅探问题。
我需要将OPTION(RECOMPILE)添加到创建存储过程的sql中。
