MySQL的编码设置

MySQL5.7中

问题再现：命令行操作sql乱码问题

mysql> INSERT INTO t_stu VALUES(1,'张三','男');
ERROR 1366 (HY000): Incorrect string value: '\xD5\xC5\xC8\xFD' for column 'sname' at
row 1

问题解决

步骤1：查看编码命令

show variables like 'character_%';
show variables like 'collation_%';

步骤2：修改mysql的数据目录下的my.ini配置文件

[mysql] #大概在63行左右，在其下添加
...
default-character-set=utf8 #默认字符集
[mysqld] # 大概在76行左右，在其下添加
...
character-set-server=utf8
collation-server=utf8_general_ci

步骤3：重启服务

# 启动 MySQL 服务命令：
net start MySQL服务名
# 停止 MySQL 服务命令：
net stop MySQL服务名

d:\kss_blog>net start mysql57
发生系统错误 5。

拒绝访问。

原因：不是以管理员身份打开终端
步骤4：查看编码命令

mysql> show variables like 'character_%'
