CREATE {DATABASE | SCHEMA} [IF NOT EXISTS] db_name [create_option] ...create_option: [DEFAULT] { CHARACTER SET [=] charset_name | COLLATE [=] collation_name} |
通过查看mysql服务器的变量我们知道mysql默认创建数据库开启的字符集是latinl：
现在我们需要给创建的数据库db2指定支持中文的字符集utf8,下面是一行的内容哦！

CREATE DATABASE db2 IF NOT EXISTS db2 DEFAULT CHARACTER SET utf8 COLLATE utf_general_ci; |
上面我们就完成支持插入中文数据的数据库的创建，现在我们来思考一个问题，支持中文的字符集就只有utf8，还有哪些呢？它们之间的区别是什么？
我们先来看一下mysql 5.7.x 支持的字符集以及字符规则：
