许多商业关系数据库系统提供对活动规则的支持，这些规则通常被称为触发器。但是，这些工具是由不同的供应商独立开发的，为一个系统开发的触发器通常不能与另一个系统一起使用。本章描述了SQL3标准如何支持触发器，特别是触发器如何与标准的其他功能相关联。
Many commercial relational database systems provide support for active rules, which are generally referred to as triggers. However, these facilities have been developed independently by different vendors, and triggers developed for one system generally do not work with another. This chapter describes how triggers are supported in the SQL3 standard, and in particular how the triggers relate to other features of the standard.
