摘要
数据库触发器是响应插入、更新和删除等数据库事件而执行的过程。本文详细叙述了Oracle触发器的功能及应用场合,并以一个实例示范用Java创建Oracle9i触发器的全过程。文尾给出了用Java开发不依赖具体数据库的稳固的触发器代码的思路。
The trigger is a responsive procedure when database events such as inserting,updating,and deleting are occurred.This paper narrates the functions of Oracle9i trigger and the occasion of application.It also gives an example to demonstrate how to program the Oracle trigger with Java.In the end the paper gives the train of thought about how to develop the firm code of trigger not relying on the concrete database with Java.
