mySQL转换字符编码的方法

1.通过配置文件修改my.ini(windows下)或/etc/my.cnf(linux下)

分别添加如下内容

[mysqld]character_server_set=utf8[mysql]default-character-set=utf8[mysql.server]default-character-set=utf8[mysql_safe]default-character-set=utf8[client]default-character-set=utf8

2.创建数据库时设置编码

create database test character set utf8;

3.创建表时设置编码

create table test(id int primary key)DEFAULT charset=utf8;

4.修改数据库编码

alter database test character set utf8;

5.修改表默认编码

alter table test character set utf8;

6.修改字段编码

alter table test modify col_name varchar(50) CHARACTER SET utf8;
