Question

我想知道如果我无法插入，是否有办法说明删除删除。

请建议。

如下所示。

BEGIN TRAN
Delete from MYTABLE where ID=@ID;

INSERT INTO MYTABLE (ID, NAME)
SELECT @ID, NAME

COMMIT

Answer 1

您可以将两个语句放入TRY....CATCH块中，只有在两个语句都成功时才提交：

BEGIN TRANSACTION
BEGIN TRY
    DELETE FROM dbo.MYTABLE WHERE ID=@ID;

    INSERT INTO dbo.MYTABLE (ID, NAME)
       SELECT @ID, NAME

    -- COMMIT only if both DELETE and INSERT worked ....
    COMMIT TRANSACTION
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber,
        ERROR_SEVERITY() AS ErrorSeverity,
        ERROR_STATE() AS ErrorState,
        ERROR_PROCEDURE() AS ErrorProcedure,
        ERROR_LINE() AS ErrorLine,
        ERROR_MESSAGE() AS ErrorMessage

    -- ROLLBACK if either DELETE and INSERT failed ....
    ROLLBACK TRANSACTION
END CATCH

启用xact_abort以在任何错误上回滚事务。

SET XACT_ABORT ON;
BEGIN TRAN
Delete from MYTABLE where ID=@ID;

INSERT INTO MYTABLE (ID, NAME)
SELECT @ID, NAME

COMMIT TRAN

Answer 3

这是完成您似乎尝试的另一种方法：

update myTable
set name = @name
where id = @id

Answer 4

BEGIN TRAN

Delete from MYTABLE where ID=@ID;

INSERT INTO MYTABLE (ID, NAME)
SELECT @ID, NAME

if @@error = 0 and @@trancount > 0
    commit
else
    rollback

如果插入失败，SQL Server存储过程将还原我的记录
