ddl_trigger_option ddl_trigger_option指定ENCRYPTION和/或EXECUTE AS子句。ENCRYPTION加密触发器的定义。EXECUTE AS定义执行触发器的安全上下文。 event_type | event_group event_type表示导致触发器触发的DDL事件,例如CREATE_TABLE、ALTER_TABLE等。 event_group是一组event_type事件,如DDL_TABLE_EVENTS。 触发器可以...
CREATE TRIGGER (Transact-SQL) SQL Server Triggers and Transactions 以前写过的笔记 介绍 触发器适合用在维护冗余. 它可以监听指定 table 的 insert, update, delete. 监听时机分 2 种, after 和 instead of after 就是在数据变化之后触发. 在 trigger 中通过访问 inserted 和 deleted 就可以获取改动前后的数...

首先,我们可以使用sys.triggers系统视图来列出数据库中的所有触发器。以下示例查询将返回当前数据库中所有表的触发器信息: SELECTt.nameAS[TableName],tr.nameAS[TriggerName],tr.create_dateAS[CreatedDate],tr.modify_dateAS[LastModifiedDate],tr.is_disabledAS[IsDisabled]FROMsys.triggers trJOINsys.tablestONtr...
You can even tell SQL Server which order you want the AFTER triggers to fire by using the system stored procedure sp_settriggerorder. However, I have rarely wanted to have more than one trigger hanging from the same table upon the same action query, and even when I did, I didn't care...
创建触发器：在SQL server Management Studio上点击需要创建触发器的表，右击触发器，点击新建，即可获得一个触发器模板，如图1、图2。模板说明如下：CREATE TRIGGER <Schema_Name, sysname, Schema_Name>.<Trigger_Name, sysname, Trigger_Name> --触发器名称 ON <Schema_Name, sysname, Schema_Name>.<Table_...
