6DD2920-3AW0触发器（trigger）是SQL server 提供给程序员和数据分析员来保证数据完整性的一种方法，它是与表事件相关的特殊的存储过程，它的执行不是由程序调用，也不是手工启动，而是由事件来触发，比如当对一个表进行操作（ insert，delete， update）时就会激活它执行。触发器经常用于加强数据的完整性约束和业务规则等。 触发器可以从 DBA_TRIGGERS ，USER_TRIGGERS 数据字典中查到。SQL3的触发器是一个能由系统自动执行对数据库修改的语句。

6DD2920-3AW0触发器可以查询其他表，而且可以包含复杂的SQL语句。它们主要用于强制服从复杂的业务规则或要求。例如：您可以根据客户当前的帐户状态，控制是否允许插入新订单。

6DD2920-3AW0触发器也可用于强制引用完整性，以便在多个表中添加、更新或删除行时，保留在这些表之间所定义的关系。然而，强制引用完整性的·好方法是在相关表中定义主键和外键约束。如果使用数据库关系图，则可以在表之间创建关系以自动创建外键约束。

6DD2920-3AW0触发器与存储过程的唯·区别是触发器不能执行EXECUTE语句调用，而是在用户执行Transact-SQL语句时自动触发执行。

6DD2920-3AW0此外触发器是逻辑电路的基本单元电路，具有记忆功能，可用于二进制数据储存，记忆信息等。
