MySQL创建数据库并支持中文字符的操作方法

我们首先看一下MySQL官方文档：5.7

CREATE {DATABASE | SCHEMA} [IF NOT EXISTS] db_name [create_option] ...create_option: [DEFAULT] { CHARACTER SET [=] charset_name | COLLATE [=] collation_name}

在这里插入图片描述

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;
