问题描述

I'm pretty new to using foreign keys, and can't really find anything on the MySQL website.我对使用外键很陌生，在 MySQL 网站上找不到任何东西。 Here is my database structure:这是我的数据库结构：

hosts
    id
    etc.
events
    id
    host_id
    etc.

One or multiple events belong to a host .一个或多个events属于一个host 。 When the host is deleted I need all events attached to it to be deleted.当host被删除时，我需要删除所有附加到它的events 。 How can I achieve this?我怎样才能做到这一点？

Thanks!谢谢！
