mysql 无法插入中文

https://democome.com

看网上说是吧my.ini中的这段代码改成utf8

[mysql]

default-character-set=utf8


# SERVER SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this 
# file.
#
[mysqld]

# The TCP/IP Port the MySQL Server will listen on
port=3306


#Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files/MySQL/MySQL Server 5.0/"

#Path to the database root
datadir="C:/Program Files/MySQL/MySQL Server 5.0/Data/"

# The default character set that will be used when a new schema or table is
# created and no character set is defined
character-set-server=utf8

改成utf8之后还是不行，后来找到一篇文章帮助解决

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 ....xB5xA5xD1xA1 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：

Server characterset:    utf8

Db      characterset:    utf8

Client  characterset:    utf8

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：

Server characterset:    utf8

Db       characterset:   utf8

Client  characterset:    gbk

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：

Server characterset:    gbk

Db      characterset:    gbk

Client  characterset:   gbk

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：

Server characterset:   gbk

Db      characterset:    utf8

Client  characterset:   utf8

Conn.  characterset:   utf8

3.当前字符集编码为utf8：

Server characterset:    gbk

Db      characterset:    gbk

Client  characterset:   utf8

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：

SET  character_set_client=gbk;

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； 

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;
