MySQL数据库 默认编码已经是 utf8 了, default-character-set = utf8,可是向数据库中表中插入中文时,却老是出现 ....\xB5\xA5\xD1\xA1 for column...这样的错误,经过查阅网上类型的错误后,发现一个很奇妙的现象,接下来我们就来开始介绍。 一、在安装数

MySQL数据库默认编码已经是utf8了, default-character-set = utf8,可是向数据库中表中插入中文时,却老是出现 ....\xB5\xA5\xD1\xA1 for column...这样的错误,经过查阅网上类型的错误后,发现一个很奇妙的现象,接下来我们就来开始介绍。

一、在安装数据库时就设定字符集编码为utf8的环境下

1.在当前字符集编码为:

 

  1. Server characterset:    utf8  
  2.  
  3. Db      characterset:    utf8  
  4.  
  5. Client  characterset:    utf8  
  6.  
  7. Conn.  characterset:    utf8 

 

下创建数据库:

(1)插入中文数据,操作不能成功。

(2)修改字符集编码为:

 

  1. Server characterset:    utf8  
  2.  
  3. Db       characterset:   utf8  
  4.  
  5. Client  characterset:    gbk  
  6.  
  7. Conn.  characterset:    gbk 

 

插入中文数据,显示正常。

二、在安装数据库时就设定字符集编码为gbk的环境下

1.当前字符集编码是:

 

  1. Server characterset:    gbk  
  2.  
  3. Db      characterset:    gbk  
  4.  
  5. Client  characterset:   gbk  
  6.  
  7. Conn.  characterset:   gbk  

 

下创建数据,插入中文数据,操作正常,显示正常。

2.当前字符集编码为utf8:

 

  1. Server characterset:   gbk  
  2.  
  3. Db      characterset:    utf8  
  4.  
  5. Client  characterset:   utf8  
  6.  
  7. Conn.  characterset:   utf8 

 

3.当前字符集编码为utf8:

 

  1. Server characterset:    gbk  
  2.  
  3. Db      characterset:    gbk  
  4.  
  5. Client  characterset:   utf8  
  6.  
  7. Conn.  characterset:   utf8 

 

插入中文数据,操作不能执行。

结论:要想能向数据库正常插入中文,必须满足以下条件:

1.要把字符集设定为能支持中文的gbk或则utf8;

2.把数据库的Client Characterset和Conn. Characterset的字符集都设定为gbk;

根据上面的提示 ,我更改了:

 

  1. SET  character_set_client=gbk;  
  2.  
  3. SET character_set_connection=gbk

 

之后再尝试想数据库插入中文,这时没有出错,能插入可是查询出来是乱码。

最后再更改; 

 

  1. SET character_set_results=gbk

 

这样之后,所有的问题都解决了,能正常插入也能正常显示了。

 

另附查看字符集命令

5.查看字符集设置

mysql> show variables like 'collation_%';

mysql> show variables like 'character_set_%';

修改字符集

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 character_set_system=utf8;

mysql> set collation_connection=utf8;

mysql> set collation_database=utf8;

mysql> set collation_server=utf8;
