Mysql查看编码方式专题

一、

查看数据库的字符集

show variables like 'character\_set\_%';

输出：

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

| Variable_name | Value |

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

| character_set_client | latin1 |

| character_set_connection | latin1 |

| character_set_database | latin1 |

| character_set_filesystem | binary |

| character_set_results | latin1 |

| character_set_server | latin1 |

| character_set_system | utf8 |

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

结合以下的编码表我们发现当前的数据库系统的编码：

latin1_bin

西欧(多语言), 二进制

binary

二进制

以上是我在linux环境中的查看的结果编码集了。我现在WIN平台上面查看编码集结果如：

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

| 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 |

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

为什么会出现不一致的情况呢？在我本机上面是显示的UTF-8.而在LINUX上面居然是

二、通过命令修改其编码

创建数据库指定数据库的字符集

mysql>create database mydb character set utf-8;#直接指定其编码

直接通过命令进行修改

set character_set_client=utf8;

set character_set_connection=utf8;

set character_set_database=utf8;

set character_set_results=utf8;

set character_set_server=utf8;

修改完了之后再查询

show variables like 'character\_set\_%';

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

| 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 |

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

结果全部都调整修改成UTF-8了！

修改完了之后我看select * from address_address; 出现乱码了！Django也乱码

三、解决数据导入导出的乱码问题

#create database nginxdjango;

# use nginxdjango;

# show variables like 'character\_set\_%';

#打印输出居然是如下

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

| Variable_name | Value |

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

| character_set_client | latin1 |

| character_set_connection | latin1 |

| character_set_database | latin1 |

| character_set_filesystem | binary |

| character_set_results | latin1 |

| character_set_server | latin1 |

| character_set_system | utf8 |

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

依旧是latin编码的。

OK。我将其编码设置一下

set character_set_client=utf8;

set character_set_connection=utf8;

set character_set_database=utf8;

set character_set_results=utf8;

set character_set_server=utf8;

再查询一下其编码格式为：+--------------------------+--------+

| 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 |

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

现在将数据导进来

source /python/django/sql/nginxdjango.sql;

其中的nginxdjango.sql 其编码也是utf-8 格式的！

导进来 数据库查看居然还是乱码不过程序跑起来是正常了！
