mysql导入乱码问题解决办法
要想导入时避免不出现乱码，只要保证数据文件的编码和导入时甚至的编码一直即可，注意：不是和数据库的编码一致。例如：数据文件data.sql，编码为UTF-8,使用如下命令：
| 代码如下 | |
|
mysql -uroot -p --default-character-set=utf8 db < data.sql |
|
上面的办法不一定有效果，因为不知道mysql编码，我们可以先查看mysql编码
| 代码如下 | |
|
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)
mysql> show variables like "%coll%"; +----------------------+-------------------+ | Variable_name | Value | +----------------------+-------------------+ | collation_connection | latin1_swedish_ci | | collation_database | utf8_bin | | collation_server | utf8_bin | +----------------------+-------------------+ |
|
修改sql文件
| 代码如下 | |
|
SET collation_connection = utf8_bin; SET character_set_client = utf8; SET character_set_connection = utf8; |
|
再执行导入
| 代码如下 | |
|
mysql --socket=/opt/mydata/my3306/my3306.sock -A < xxx.sql 就好了... |
|
还发现一个程序导入乱码解决办法,就是在mysql_connect后面加一句SET NAMES UTF8，即可使得UTF8的数据库消除乱码，对于GBK的数据库则使用SET NAMES GBK，代码如下：
| 代码如下 | |
| $mysql_mylink = mysql_connect($mysql_host, $mysql_user, $mysql_pass); mysql_query("SET NAMES 'GBK'"); |
|
数据库字符集为utf-8
连接语句用这个
| 代码如下 | |
| mysql_query("SET NAMES 'UTF8'"); mysql_query("SET CHARACTER SET UTF8"); mysql_query("SET CHARACTER_SET_RESULTS=UTF8'"); |
|
