Question

每当任何一个查询失败时，我都需要回滚事务。如果所有事务都没有问题，则必须设置输出参数。

到目前为止，我已经这样做了。

create PROCEDURE [dbo].[sp_InsertAll]
-- Add the parameters for the stored procedure here
@WO_Type varchar(25),
@WO_Operation varchar(25),
@WO_Source varchar(25),
@RETVAL BIT OUT
AS
BEGIN
    SET NOCOUNT ON;

    SET @RETVAL = 0
    SET XACT_ABORT ON

    BEGIN TRAN;

      INSERT INTO tblTabl1(WO_Type ,  WO_Operation , WO_Source )
      VALUES (@WO_Type, @WO_Operation, @WO_Source, )

      IF @UPDATESOURCE = 1
      BEGIN
          UPDATE tblT2 
          SET SM_SaddleStatus = @SOURCESTATUS 
          WHERE SM_SaddleID = @WO_SourceID
      END   

      IF @UPDATEDESTINATION = 1
      BEGIN
          UPDATE tblT3 
          SET SM_SaddleStatus = @DESTINATIONSTATUS 
          WHERE SM_SaddleID = @WO_DestinationID
      END

      SET @RETVAL = 1
      COMMIT TRAN;
END

这是返回价值的正确方法吗？这个方法有什么问题吗？到目前为止它对我来说很好。在开始生产之前，我需要交叉检查。

这就是我的建议，使用TSQL Try Catch块回滚事务并为您提供不同的返回值：

create PROCEDURE [dbo].[sp_InsertAll]
-- Add the parameters for the stored procedure here
@WO_Type varchar(25),
@WO_Operation varchar(25),
@WO_Source varchar(25),
--@RETVAL BIT OUT
AS

BEGIN
SET NOCOUNT ON;

SET @RETVAL = 0
SET XACT_ABORT ON

BEGIN TRAN;
    BEGIN TRY
              INSERT INTO tblTabl1(WO_Type ,  WO_Operation , WO_Source )
              VALUES (@WO_Type, @WO_Operation, @WO_Source, )

              IF @UPDATESOURCE = 1
              BEGIN
                  UPDATE tblT2 
                  SET SM_SaddleStatus = @SOURCESTATUS 
                  WHERE SM_SaddleID = @WO_SourceID
              END   

              IF @UPDATEDESTINATION = 1
              BEGIN
                  UPDATE tblT3 
                  SET SM_SaddleStatus = @DESTINATIONSTATUS 
                  WHERE SM_SaddleID = @WO_DestinationID
              END

            return 0
            COMMIT TRAN;
    END TRY
    BEGIN CATCH
            rollback Tran;
            return -1
    END CATCH
END
