复制代码 代码如下:
— Create a log table
CREATE TABLE TriggerLog (LogInfo xml)
— Create a dummy table to delete later on
CREATE TABLE TableToDelete (Id int PRIMARY KEY)
— 新建一个新表,作为删除实验表
INSERT INTO TableToDelete VALUES(1)
GO
— 创建一个Drop Table 的 DDL
CREATE TRIGGER StopTableDrop ON DATABASE AFTER DROP_TABLE
AS
DECLARE @EventData AS xml
SET @EventData = EVENTDATA() — 必须要在rollback之前截获DDL信息
ROLLBACK
PRINT ‘DROP TABLE attempt in database ‘ + DB_NAME() + ‘.’
INSERT INTO TriggerLog VALUES(@EventData)
执行如下删除操作:
DROP TABLE TableToDelete
会触发上面的DDL,从而回滚操作。
执行下面的Sql:
SELECT * FROM TriggerLog
查看刚才截获的DDL信息。
