7. Triggers
Last but least, you need to learn about triggers. Triggers are similar to stored procedures in that they are groupings of SQL statements. The major difference is how triggers are executed. Triggers are executed when a row is inserted, updated, or deleted from a table, depending on how the triggers were created. Triggers are a powerful way to enforce business rules when data is modified. A single table can have up to three different triggers on it. You can have a trigger that fires when an UPDATE occurs, one that fires when an INSERT occurs, and one that fires when a DELETE occurs. Triggers can be a way that the SQL Server automates business processes. For example, when an author has sold enough books to cover the advance that the publishing company paid, a trigger could be used to automatically begin calculating the royalty payments. Triggers fire after the record has been successfully modified in the table. If the modification fails because of a syntax error or constraint violation, the trigger is not fired.
You need to be aware of one point of caution when dealing with triggers. Although triggers can be very powerful, they can also be very damaging to the performance of your server. Be very careful that you do not try to put too much functionality into your triggers because it will slow down response and can really frustrate your users.

触发器
最后,但至少,你需要了解触发.触发器存储程序类似,他们是集团的SQL声明.主要的区别是如何引发的处决.当连续触发的执插入更新或删除表视乎引发创造.触发器是一支强大的执行方式是当数据业务规则改装.单表最多可以有三种不同触发它.你能有更新时引发火灾,发生火灾时,一插入时,一到火灾发生时删除.触发器可以作为SQLServer的自动化的业务流程.举例来说,当一个作家已售出图书不够支付提前支付的出版公司,一个可以用来触发自动开始计算版权费.引发火警后已成功修改记录表.如果不修改,因为违反了语法错误或约束,引发不开火.你需要了解一点谨慎处理触发.虽然触发器可以很强大,也可以很破坏你服务器的表现.你必须非常小心,不要把太多的功能,因为它会变成你触发反应慢、贵用户能真正挫败.
