mysql怎么改字符编码？

mysql命令行修改字符编码

1、修改数据库字符编码mysql> alter database mydb character set utf8 ;2、创建数据库时，指定数据库的字符编码mysql> create database mydb character set utf8 ;3、查看mysql数据库的字符编码mysql> show variables like 'character%'; //查询当前mysql数据库的所有属性的字符编码+--------------------------+----------------------------+| Variable_name| Value|+--------------------------+----------------------------+| character_set_client| latin1|| character_set_connection | latin1|| character_set_database| utf8|| character_set_filesystem | binary|| character_set_results| latin1|| character_set_server| utf8|| character_set_system| utf8|| character_sets_dir| /usr/share/mysql/charsets/ |+--------------------------+----------------------------+4、修改mysql数据库的字符编码

修改字符编码必须要修改mysql的配置文件my.cnf,然后重启才能生效

通常需要修改my.cnf的如下几个地方：

【client】下面，加上default-character-set=utf8，或者character_set_client=utf8

【mysqld】下面，加上character_set_server = utf8 ；

因为以上配置，mysql默认是latin1，如果仅仅是通过命令行客户端，mysql重启之后就不起作用了。

如下是客户端命令行修改方式，不推荐使用mysql> set character_set_client=utf8 ;mysql> set character_set_connection=utf8 ;mysql> set character_set_database=utf8 ;mysql> set character_set_database=utf8 ;mysql> set character_set_results=utf8 ;mysql> set character_set_server=utf8 ;mysql> set character_set_system=utf8 ;mysql> show variables like 'character%';+--------------------------+----------------------------+| Variable_name| Value|+--------------------------+----------------------------+| character_set_client| utf8|| character_set_connection | utf8|| character_set_database| utf8|| character_set_filesystem | binary|| character_set_results| utf8|| character_set_server| utf8|| character_set_system| utf8|| character_sets_dir| /usr/share/mysql/charsets/ |+--------------------------+----------------------------+8 rows in set (0.00 sec)以上就是mysql怎么改字符编码？的详细内容，更多请关注小潘博客其它相关文章！
