實體框架存儲過程調用超時

Question

這是一個奇怪的..

我的數據庫中有一個存儲過程，如下所示：

SET NOCOUNT ON;
    WITH CTE AS(

        --FC
        SELECT transno, RECHASEON,
            convert(varchar(12),orderdate, 101) as orderdate,
            convert(varchar(12),duedate, 101) as duedate,
            m.clientid+'-'+l.name as clientname,
            (SELECT TOP 1c.Comments FROM dbo.qcComments c WHERE m.transno = c.transno ORDER BY c.Comment_Date DESC) as MostRecentComment,
            'FC' as PortalType,
            (SELECT COUNT(*) FROM dbo.qcComments c WHERE m.transno = c.transno) AS NumTimesKickedBack,
             m.SubRep,
             m.ClientID,
            (SELECT convert(varchar(12),MAX(c.Comment_Date), 101) FROM dbo.qcComments c WHERE m.transno = c.transno) as MostRecentReturnDate,
            (SELECT TOP 1 c.UserID FROM dbo.qcComments c WHERE m.transno = c.transno ORDER BY c.Comment_Date DESC) AS LastUserKickBack

        FROM dbo.maindata m (NOLOCK)
        inner join bluscreen.dbo.Lender L (NOLOCK) on L.clientid = M.clientid

        where m.cid = @CID  
        and ((@userlevel='SUBREP' and m.subrep=@UserName) or (@UserLevel<>'SUBREP'))
        and m.RCD=''    -- open assignment
        and exists (    -- qc kickback comments exist for the transno
            select transno

                'RPI' as PortalType,
                (SELECT COUNT(*) FROM rpi.dbo.msgbrd c WHERE m.transno = c.transno and c.msgtype= 'QC') as NumTimesKickedBack,

                (SELECT TOP 1 c.username FROM rpi.dbo.msgbrd c WHERE m.transno = c.transno and c.msgtype= 'QC' ORDER BY c.datetime DESC) AS LastUserKickBack

        FROM webdata.dbo.MainData m
        INNER JOIN  rpi.dbo.Requests r on m.TransNo=r.transno
        INNER JOIN bluscreen.dbo.Lender l on l.clientid = m.clientid
        INNER JOIN rpi.dbo.msgbrd msg on m.TransNo=msg.transno and msgtype='QC' --This join is used to check where a TransNo has been kicked back
        where m.RCD=''          --open
        AND r.qcpending='ON'    --qc kickback
        AND m.CID = @CID 
        and ((@userlevel='SUBREP' and m.subrep=@UserName) or (@UserLevel<>'SUBREP'))

        UNION 

        --LM
        select  m.TransNo,
                m.RechaseON,
                convert(varchar(12), m.OrderDate, 101),
                convert(varchar(12),m .DueDate, 101),
                m.clientid+'-'+l.name as clientname,
                (SELECT TOP 1 c.NOTES FROM LossMitigation.dbo.Translog_Call c WHERE m.transno = c.transno and c.CALL_RESULT_CODE = 'DIS' ORDER BY c.DATETIME_ENTRY DESC) as MostRecentComment,
                'LM' as PortalType,

        from webdata.dbo.MainData m
        INNER JOIN lossmitigation.dbo.Requests r on m.TransNo=r.TRANSNO
        INNER JOIN lossmitigation.dbo.Translog_Call t on m.TransNo=t.TRANSNO and t.CALL_RESULT_CODE='DIS' --This join is used to check where a TransNo has been kicked back
        INNER JOIN bluscreen.dbo.Lender l on l.clientid = m.clientid
        where r.Status='PENDING' --open assignment
        AND m.CID = @CID 
        and ((@userlevel='SUBREP' and m.subrep=@UserName) or (@UserLevel<>'SUBREP'))
    )

    SELECT * FROM cte
    ORDER BY
            CASE
                WHEN @SortBy = 'Rechase' THEN RechaseON     
            END DESC,

            CASE
                WHEN @SortBy = 'NumKickbacks' THEN NumTimesKickedBack   
            END DESC,

            CASE 
                WHEN @SortBy = 'TransNo' THEN TransNo
                WHEN @SortBy = 'ClientID' THEN ClientName
                WHEN @SortBy = 'Subrep' THEN Subrep 
                WHEN @SortBy = 'LastKickbackUser' THEN LastUserKickBack

            CASE 
                WHEN @SortBy = 'OrderDate' THEN OrderDate
                WHEN @SortBy = 'DueDate' THEN DueDate
                WHEN @SortBy = 'ReturnDate' THEN MostRecentReturnDate   
                ELSE TransNo    
            END ASC

在我的代碼中，我使用實體框架調用了存儲過程，如下所示：

using webDataDBContext = new WebDataEntities() {
var data = webDataDBContext.view_inqc_manifest_cid_II("11R", "REP", "rpfield", "TransNo").ToList()
}

如果我在服務器上運行存儲過程，它會在不到一秒的時間內執行。 它運行這個查詢：

 EXEC [dbo].[view_inqc_manifest_cid_II] '11R', 'REP', 'rpField', 'TransNo'

然而，.NET 中的等效項運行時間超過 100 秒（我取消了查詢，因為運行時間太長）。 我完全不知道為什么 .NET 存儲過程調用需要這么長時間，它執行完全相同的查詢。

有誰知道為什么會這樣？

我沒有給表加鎖，它工作起來很奇怪，因為它在網站的舊版本中工作......一定與實體框架有關
