mysql 从文件导入sql 乱码问题该怎么解决，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
首先我拿到sql文件没乱码,(用ultraedit 管理员界面可以看到文件编码)
数据库编码和文件一致
下面就进到mysql里面看看variables
www.2cto.com
mysql> show variables like "%char%";
+--------------------------+---------------------------------------------------------------------------------+
| Variable_name | Value |
+--------------------------+---------------------------------------------------------------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | latin1 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/Percona-Server-5.1.57-rel12.8-233--x86_64/share//charsets/ |
+--------------------------+---------------------------------------------------------------------------------+
8 rows in set (0.01 sec)
www.2cto.com
mysql> show variables like "%coll%";
+----------------------+-------------------+
| Variable_name | Value |
+----------------------+-------------------+
| collation_connection | latin1_swedish_ci |
| collation_database | utf8_bin |
| collation_server | utf8_bin |
+----------------------+-------------------+
3 rows in set (0.00 sec)
有几个latin1的...
原来是connection的变量是latin1... 忍不了
修改sql文件
SET collation_connection = utf8_bin;
SET character_set_client = utf8;
SET character_set_connection = utf8;
mysql --socket=/opt/mydata/my3306/my3306.sock -A < xxx.sql 就好了...
