-- 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。SQLServer EVENTDATA()函数来获取DDL 触发器信息
