我使用此查询在表 tblWorkOrders 中插入一行。但是@@ROWCOUNT 即使在表中插入了一行，也会给出 0。可能是什么原因？如何更改查询以提供正确的@@ROWCOUNT？

INSERT INTO tblWorkOrders
        (           WO_Type , WO_Yard , WO_Operation , WO_Source , WO_SourceID , WO_SourceXLocation , WO_SourceYLocation , 
                    WO_Destination , WO_DestinationID , WO_DestinationXLoc, WO_DestinationYLoc , WO_Crane , WO_Priority , 
                    WO_ScheduledAt , WO_CoilNo , WO_ExecutionStart , WO_ExecutionEnd , WO_ExecutedBy , WO_Remarks,WO_RequestRefID )

        ( SELECT    OM_WOType,OM_Yard,OM_OperationsID,'Saddle' ,STARTINGPOINT.NAME,STARTINGPOINT.XAxis,STARTINGPOINT.YAxis,
                    'Saddle',ENDINGPOINT.NAME,ENDINGPOINT.XAxis,ENDINGPOINT.YAxis,OM_AssignedCrane,NULL,
                    NULL,@COILNO,NULL,NULL,NULL,NULL,NULL
                    FROM 

                    tblOperationsMaster OPM

                    INNER JOIN 
                    (SELECT SP_OperatingPointID AS [NAME],SP_XLocation AS [XAxis],SP_YLocation AS [YAxis] FROM tblStandardPoints
                    UNION ALL
                    SELECT SM_SaddleID AS [NAME],SM_XCoordinate AS [XAxis],SM_YCoordinate AS [YAxis] FROM tblSaddleMaster) STARTINGPOINT
                    ON STARTINGPOINT.NAME = @SOURCEIDFROMCALLINGFN

                    INNER JOIN 
                    (SELECT SP_OperatingPointID AS [NAME],SP_XLocation AS [XAxis],SP_YLocation AS [YAxis] FROM tblStandardPoints
                    UNION ALL
                    SELECT SM_SaddleID AS [NAME],SM_XCoordinate AS [XAxis],SM_YCoordinate AS [YAxis] FROM tblSaddleMaster) ENDINGPOINT 
                    ON ENDINGPOINT.NAME = @DESTINATIONIDFROMCALLINGFN

                    WHERE OPM.OM_OperationsID = @OPERATIONID)

        SET @ROWSINSERTED = @@ROWCOUNT;

【解决方案1】：

您好，您将通过以下方式获得rowcount：

SELECT @ROWSINSERTED =@@ROWCOUNT

希望对你有帮助

试试这个，

我已经提供了示例检查它。

插入后使用。

SELECT @ROWSINSERTED=@@ROWCOUNT
SELECT @ROWSINSERTED AS Rows

        ( SELECT    OM_WOType,OM_Yard,OM_OperationsID,'Saddle' ,STARTINGPOINT.NAME,STARTINGPOINT.XAxis,STARTINGPOINT.YAxis,
                    'Saddle',ENDINGPOINT.NAME,ENDINGPOINT.XAxis,ENDINGPOINT.YAxis,OM_AssignedCrane,NULL,
                    NULL,@COILNO,NULL,NULL,NULL,NULL,NULL
                    FROM 

                    tblOperationsMaster OPM

                    INNER JOIN 
                    (SELECT SP_OperatingPointID AS [NAME],SP_XLocation AS [XAxis],SP_YLocation AS [YAxis] FROM tblStandardPoints
                    UNION ALL
                    SELECT SM_SaddleID AS [NAME],SM_XCoordinate AS [XAxis],SM_YCoordinate AS [YAxis] FROM tblSaddleMaster) STARTINGPOINT
                    ON STARTINGPOINT.NAME = @SOURCEIDFROMCALLINGFN

                    INNER JOIN 
                    (SELECT SP_OperatingPointID AS [NAME],SP_XLocation AS [XAxis],SP_YLocation AS [YAxis] FROM tblStandardPoints
                    UNION ALL
                    SELECT SM_SaddleID AS [NAME],SM_XCoordinate AS [XAxis],SM_YCoordinate AS [YAxis] FROM tblSaddleMaster) ENDINGPOINT 
                    ON ENDINGPOINT.NAME = @DESTINATIONIDFROMCALLINGFN

                    WHERE OPM.OM_OperationsID = @OPERATIONID)
DECLARE @Rows int
SELECT @Rows=@@ROWCOUNT
SELECT @Rows AS Rows,@@ROWCOUNT AS [ROWCOUNT]

试试这个，我认为它会工作
