之前讲了如何查询mysql字符集,接下来若需要修改字符集如何操作呢,下面介绍修改默认字符集的方法

一、 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" |   
+--------------------------+---------------------------------+  

二、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 ; 

有时候就算设置了表的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:

SET NAMES 'utf8'; 

它相当于下面的三句指令:

SET character_set_client = utf8;  
SET character_set_results = utf8;   
SET character_set_connection = utf8; 

辛苦码子,希望对你有帮助。
