触发器在数据库编程中的应用

针对当前数据库编程中数据不匹配的现象,采用触发器可以有效地解决这方面的问题。首先介绍了触发器的概念、优点及作用;其次从触发器的原理、使用注意事项、创建、查看、修改、修改触发器及触发器嵌套等几个方面来介绍触发器的使用;最后将SQL与C#语言相结合,给出了查询触发器与修改触发器的核心代码。对于数据库管理人员和软件开发人员有着一定的积极作用。

Application of Triggers in Database Programming

Triggers can solve data’s mismatches in current database programming effectively. This paper first introduces the concept, advantages and role of the trigger;followed by the use of nested triggers, such as principle, precautions, creation, view, modification of trigger, modification of trigger and other aspects the last part is combining SQL and C # language, and give the core code of querying and modifying the trigger. This paper has a certain positive role for database administrators and software developers.
