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！
MySQL字符集编码的类型种类
