(1) 最简单的修改方法,就是修改mysql的my.ini文件中的字符集键值,

如 default-character-set = utf8
character_set_server = utf8

修改完后,重启mysql的服务,service mysql restart

使用 mysql> SHOW VARIABLES LIKE 'character%';查看,发现数据库编码均已改成utf8

  1. +--------------------------+---------------------------------+
  2. | Variable_name | Value |
  3. +--------------------------+---------------------------------+
  4. | character_set_client | utf8 |
  5. | character_set_connection | utf8 |
  6. | character_set_database | utf8 |
  7. | character_set_filesystem | binary |
  8. | character_set_results | utf8 |
  9. | character_set_server | utf8 |
  10. | character_set_system | utf8 |
  11. | character_sets_dir | D:"mysql-5.0.37"share"charsets" |
  12. +--------------------------+---------------------------------+

(2) 还有一种修改mysql默认字符集的方法,就是使用mysql的命令

  1. mysql> SET character_set_client = utf8 ;
  2. mysql> SET character_set_connection = utf8 ;
  3. mysql> SET character_set_database = utf8 ;
  4. mysql> SET character_set_results = utf8 ;
  5. mysql> SET character_set_server = utf8 ;
  6. mysql> SET collation_connection = utf8 ;
  7. mysql> SET collation_database = utf8 ;
  8. mysql> SET collation_server = utf8 ;

一般就算设置了表的mysql默认字符集为utf8并且通过UTF-8编码发送查询,你会发现存入数据库的仍然是乱码。问题就出在这个connection连接层上。解决方法是在发送查询前执行一下下面这句:

  1. SET NAMES 'utf8';

它相当于下面的三句指令:

  1. SET character_set_client = utf8;
  2. SET character_set_results = utf8;
  3. SET character_set_connection = utf8;
