MySQL8.0

There are over 250 new features in MySQL 8.0. The MySQL Manual is very good, but verbose. This is a list of new features in short bullet form. We have tried very hard to make sure each feature is only mentioned once.

从MySQL8.0.3开始，MySQL支持一种新的优化Hint，名字叫SET_VAR,这个特性支持用户在查询语句里修改MySQL数据库的一些会话变量，当然修改只是对当前查询会话生效，不会影响到其他会话。
