SQLServer EVENTDATA()函数来获取DDL 触发器信息

-- 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)
