本文章总结了mysql导入导出数据中文乱码解决方法,出现中文乱码一般情况是导入导入时编码的设置问题,我们只要把编码调整一致即可解决此方法,下面是百度搜索到的一些方法总结。

linux系统中

linux默认的是utf8编码,而windows是gbk编码,所以会出现上面的乱码问题。

解决mysql导入导出数据乱码问题

首先要做的是要确定你导出数据的编码格式,使用mysqldump的时候需要加上--default-character-set=utf8,

例如下面的代码:

 代码如下 复制代码

mysqldump   -uroot  -p  --default-character-set=utf8   dbname tablename  >  bak.sql


那么导入数据的时候也要使用--default-character-set=utf8:

 代码如下 复制代码

mysql -uroot -p --default-character-set=utf8 dbname

这样统一编码就解决了mysql数据迁移中的乱码问题了


我使用windows作为导出数据源,并导入 freebsd环境下的mysql库

解决方法:

导出数据

一、首先在windows平台下mysql用作导出数据库源。查看字符编码的系统变量:

 

 代码如下 复制代码
 代码如下 复制代码
mysql> show variables like ‘%char%’;

+————————–+—————————-+
| 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 | gbk |
| character_set_system | utf8 |
| character_sets_dir | D:mysqlsharecharsets |

+————————–+—————————-+
查看character_set_database,这里是latin1,latin1是装不了多字节字符集的

二、在windows下设置系统变量为utf8

 代码如下 复制代码

mysql>set character_set_database=utf8; ##设置默认的字符集为utf8

三、导出数据

 代码如下 复制代码

mysql> select * from table into outfile ‘c:table.txt’ where +条件

这时导出了我想要的部分数据,并以txt文件存在 table.txt中。

导入数据

在freebsd平台下

一、同样设置字符编码的系统变量

 代码如下 复制代码

mysql> show variables like ‘%char%’;

+————————–+—————————-+
| 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 | gbk |
| character_set_system | utf8 |
|
+————————–+—————————-+

mysql>set character_set_database=utf8; ##设置默认的字符集为utf8

二、转载数据

 

 代码如下 复制代码
mysql>load data local infile ‘/home/table.txt’ into table `table`;

至此、条件数据完整导入导出,并处理了乱码的情况。
总之,两台mysql服务器导入导出时,一定要确保两台服务器的character_set_database参数相同,这样才能防止一些 乱码的情况。当然我们还可以使用其他字符集,如gbk来进行调整。视情况操作了


解决方法三

乱码解决方法
导入数据后,在命令行查看发现中文乱码
使用以下命令查看系统字符集

 代码如下 复制代码
show variables like 'char%';

如果不是GBK或UTF8,则停止mysql服务,然后到安装目录修改my.ini文件,
将文件中下面的变量改成如下,如果没有这个变量则增加这些变量

 代码如下 复制代码

[mysql]
default-character-set=gbk

[mysqld]
character-set-server=utf8

重新启动服务,重新导入数据,如果还乱码,

最后得出经验时只要把导入与导出编码统一一下就没问题了。
