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
(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 7 mysql> SET collation_connection = utf8 ; 8 mysql> SET collation_database = utf8 ; 9 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;
还有一个最简单的方法, 安装的时候选择字符集 .如图
