只要三步,完全解决数据库中文乱码问题

本文主要是介绍只要三步,完全解决数据库中文乱码问题，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

    前几天安装MySQL的时候,发现根本没法输入中文,都是乱码,然后在网上查了找了很多文章,整理一下,留作笔记.

    不出意外的话,应该有各种latin1,这就是我们要解决掉的

1. 修改my.ini

   在 D:\MySQL\MySQL Server 5.5\my.ini文件中,找到# CLIENT SECTION下面的[mysql],做如下修改

   default-character-set=utf8, 具体如下

# CLIENT SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
#
[client]
port=3306
[mysql]
default-character-set=utf8
# SERVER SECTION

2.修改好以后,再次查看编码格式,你会发现仍旧有一个latin1:

    | character_set_server     | latin1   |

    下面,找到 D:\Program Files\MySQL\MySQL Server 5.5\bin\MySQLInstanceConfig.exe

    重新配置数据库编码格式为utf8.

3. 到这一步的时候,再次查看编码格式,你会发现你的编码格式如下:

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+---------------------------------------------------------+
| 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:\Program Files\MySQL\MySQL Server 5.0\share\charsets\ |
+--------------------------+---------------------------------------------------------+

    理论上讲,编码格式应该是设置成功了的,但是在Windows系统下,试图通过 MySQL Command Line Client进行insert操作肿么还是乱码呢? 原来是MySQL Command Line Client出了幺蛾子 !因为它的显示有问题

    好吧,给一个简单到哭的指令:

set names gbk;

    果然很简单,但是效果是立竿见影,瞬间所有的问题都解决了.

附1:理想编码格式:

mysql> show variables like '%char%';
+--------------------------+---------------------------------------------------------+
| Variable_name            | Value     |
+--------------------------+---------------------------------------------------------+
| character_set_client     | gbk     |
| character_set_connection | gbk     |
| character_set_database   | utf8    |
| character_set_filesystem | binary  |
| character_set_results    | gbk     |
| character_set_server     | utf8    |
| character_set_system     | utf8    |
| character_sets_dir       | D:\Program Files\MySQL\MySQL Server 5.5\share\charsets\ |
+--------------------------+---------------------------------------------------------+
8 rows in set (0.00 sec)
