(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
复制代码 代码如下:
+--------------------------+---------------------------------+
|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
复制代码 代码如下:
mysql>SETcharacter_set_client=utf8;
mysql>SETcharacter_set_connection=utf8;
mysql>SETcharacter_set_database=utf8;
mysql>SETcharacter_set_results=utf8;
mysql>SETcharacter_set_server=utf8;
mysql>SETcollation_connection=utf8;
mysql>SETcollation_database=utf8;
mysql>SETcollation_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:
复制代码 代码如下:
SET NAMES 'utf8';
它相当于下面的三句指令:
复制代码 代码如下:
SETcharacter_set_client=utf8;
SETcharacter_set_results=utf8;
SETcharacter_set_connection=utf8;
