mysql默认字符集能否进行修改呢?答案是肯定的,下面就将教您两种修改MySQL默认字符集的方法,希望对您学习mysql默认字符集方面能有所启迪。
(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
- +--------------------------+---------------------------------+
- 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 D:"mysql-5.0.37"share"charsets"
- +--------------------------+---------------------------------+
(2) 还有一种修改mysql默认字符集的方法,就是使用mysql的命令
- mysql>SET character_set_client = utf8 ;
- mysql> SET character_set_connection =utf8;
- mysql>SET character_set_database =utf8;
- mysql> SET character_set_results =utf8;
- mysql>SET character_set_server = utf8 ;
- mysql>SET collation_connection = utf8 ;
- mysql> SET collation_database = utf8 ;
- 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:
它相当于下面的三句指令:
- SETcharacter_set_client =utf8;
- SET character_set_results =utf8;
- SETcharacter_set_connection= utf8;
