MySQL创建数据库并支持中文字符的 *** 作方法

MySQL创建数据库并支持中文字符的 *** 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
}

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：

mysql> SELECT version();
+-----------+
| version() |
+-----------+
| 5.7.32 |
+-----------+
1 row in set (0.00 sec)

mysql> SHOW CHARACTER SET;
