mysql中文乱码的完美解决方案

问题描述： mysql插入中文时显示为乱码或"?"号

解决方案：

修改mysql的my.ini配置

[mysql]
default_character_set=utf8
[mysqld]
character_set_server=utf8

千万注意：

my.ini配置完成之后不但要重启服务，而且要重建所有存在乱码的数据库，是的，不是表，而是整个库，所以最好从一开始就处理好中文乱码问题，否则必将万劫不复！

show variables like "%char%";

(本次启动有效，治标不治本)

set names utf8：

(永久有效)

my.ini

default_character_set=utf8

+--------------------------+---------------------------------------------------+

| character_set_client     | utf8                                               |

| character_set_connection | utf8                                               |

| character_sets_dir       | c:\wamp\bin\mysql\mysql5.6.17\share\charsets\ |

+--------------------------+---------------------------------------------------+

(永久有效，效果同[client]修改)

my.ini

[mysql]

default_character_set=utf8

+--------------------------+---------------------------------------------------+

| character_set_client     | utf8                                               |

| character_set_connection | utf8                                               |

(永久有效,中文完美显示,避免了每次Insert数据前都先要set names utf8一下)

my.ini

[mysql]

default_character_set=utf8

[mysqld]

character_set_server=utf8
