如果插入失敗，SQL Server存儲過程恢復我的記錄

Question

我想知道是否有一種方法來狀態回滾刪除，如果我不能插入。

請指教。

像下面這樣的東西。

BEGIN TRAN 
Delete from MYTABLE where ID=@ID; 

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

COMMIT 

Answer 1

你可以把你的兩個語句爲TRY....CATCH塊，只承諾如果兩個語句成功：

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 

Answer 2

這裏是另一種方式來完成你看起來是在嘗試：

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

Answer 3

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 

Answer 4

打開xact_abort以回滾任何錯誤的事務。

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

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

COMMIT TRAN
