Question

我有多个delete语句，它们看起来与下面的内容相似。但是，我想记录每个表删除的row_count以及事务状态。如何获得事务中的删除是否成功完成并将其记录在我拥有的Delete_Log_table中的信息。另外，如果删除失败，我将不得不停止删除操作。

请帮助：

BEGIN TRANSACTION 

DELETE FROM [DB].[SCHEMA].[EXAMPLE_TABLE]
WHERE MY_ID IN (SELECT MY_ID FROM #TEMP_TABLE)

COMMIT TRANSACTION

INSERT INTO [DELETE_LOG_TABLE] 
(TABLE_NAME, ROW_COUNT_DELETED, STATUS_OF_TRANSACTION, LOAD_DATE)
('EXAMPLE_TABLE',@@ROWCOUNT, 'HOW DO I GET COMMIT/ROLLBACK HERE- HELP', GETDATE())

您需要使用TRY和CATCH来满足需要。这是您的示例：

BEGIN TRY
    BEGIN TRANSACTION 

    DELETE FROM [DB].[SCHEMA].[EXAMPLE_TABLE]
    WHERE MY_ID IN (SELECT MY_ID FROM #TEMP_TABLE)

    INSERT INTO [DELETE_LOG_TABLE] 
    (TABLE_NAME, ROW_COUNT_DELETED, STATUS_OF_TRANSACTION, LOAD_DATE)
    ('EXAMPLE_TABLE',@@ROWCOUNT, 'Successful', GETDATE())

    COMMIT TRANSACTION

END TRY
BEGIN CATCH

    INSERT INTO [DELETE_LOG_TABLE] 
    (TABLE_NAME, ROW_COUNT_DELETED, STATUS_OF_TRANSACTION, LOAD_DATE)
    ('EXAMPLE_TABLE',0, 'Error. Detail is :'+ERROR_MESSAGE(), GETDATE())


    ROLLBACK TRANSACTION
END CATCH

记录交易状态提交/回滚
