mysql查询数据库字符编码1_MySql查看数据库的字符集

一、查看数据库的字符集

show variables like &＃39;character\_set\_%&＃39;;

输出&＃xff1a;

&＃43;--------------------------&＃43;--------&＃43;

| Variable_name| Value|

&＃43;--------------------------&＃43;--------&＃43;

| 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|

&＃43;--------------------------&＃43;--------&＃43;

结合以下的编码表我们发现当前的数据库系统的编码&＃xff1a;

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&＃xff1a;

&＃43;--------------------------&＃43;--------&＃43;

| Variable_name| Value|

&＃43;--------------------------&＃43;--------&＃43;

| 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|

&＃43;--------------------------&＃43;--------&＃43;

为什么会出现不一致的情况呢&＃xff1f;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&＃61;utf8;

set character_set_connection&＃61;utf8;

set character_set_database&＃61;utf8;

set character_set_results&＃61;utf8;

set character_set_server&＃61;utf8;

修改完了之后再查询

show variables like &＃39;character\_set\_%&＃39;;

&＃43;--------------------------&＃43;--------&＃43;

| Variable_name| Value|

&＃43;--------------------------&＃43;--------&＃43;

| 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|

&＃43;--------------------------&＃43;--------&＃43;

结果全部都调整修改成UTF-8了&＃xff01;

修改完了之后我看 select * from address_address;出现乱码了&＃xff01;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 &＃39;character\_set\_%&＃39;;

#打印输出居然是如下

&＃43;--------------------------&＃43;--------&＃43;

| Variable_name| Value|

&＃43;--------------------------&＃43;--------&＃43;

| 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|

&＃43;--------------------------&＃43;--------&＃43;

依旧是latin编码的。

OK。我将其编码设置一下

set character_set_client&＃61;utf8;

set character_set_connection&＃61;utf8;

set character_set_database&＃61;utf8;

set character_set_results&＃61;utf8;

set character_set_server&＃61;utf8;

再查询一下其编码格式为&＃xff1a;

&＃43;--------------------------&＃43;--------&＃43;

| Variable_name| Value|

&＃43;--------------------------&＃43;--------&＃43;

| 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|

&＃43;--------------------------&＃43;--------&＃43;

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&＃xff01;

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&＃xff01;

MySQL字符集编码的类型种类

gb2312_chinese_ci和gbk_chinese_ci以及gb2312_bin,gbk_bin的区别

gb2312_chinese_CI :只支持简体中文

gb2312_BIN   :而gb2312_bin可以说是gb2312_chinese_ci的一个子集&＃xff0c;

而且gb2312_BIN是二进制存储.区分大小写数据库编码格式就意义不一样了gbk_chinese_CI支持简体中文和繁体

gbk_bin解释同gb2312_BIN对应gbk_chinese_CI

PS&＃xff1a;GBK包括了简体与繁体两种类型
