mysql导入乱码问题解决办法

很多朋友可能会碰到在利用命令或phpmyadmin导入数据时出现中文乱码问题了,下面我来给大家介绍解决导入乱码的方法,有需要的朋友可参考.

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:

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:

1. mysql> show variables like "%char%"; 
2.  
3. +--------------------------+---------------------------------------------------------------------------------+ 
4.  
5. | Variable_name            | Value                                                                           | 
6.  
7. +--------------------------+---------------------------------------------------------------------------------+ 
8.  
9. | character_set_client     | latin1                                                                          | 
10.  
11. | character_set_connection | latin1                                                                          | 
12.  
13. | character_set_database   | utf8                                                                            | 
14.  
15. | character_set_filesystem | binary                                                                          | 
16.  
17. | character_set_results    | latin1                                                                          | 
18.  
19. | character_set_server     | utf8                                                                            | 
20.  
21. | character_set_system     | utf8                                                                            | 
22.  
23. | character_sets_dir       | /usr/local/Percona-Server-5.1.57-rel12.8-233--x86_64/share//charsets/ | 
24.  
25. +--------------------------+---------------------------------------------------------------------------------+ 
26.  
27. 8 rows in set (0.01 sec) 
28.  
29.  
30.  
31. mysql> show variables like "%coll%"; 
32.  
33. +----------------------+-------------------+ 
34.  
35. | Variable_name        | Value             | 
36.  
37. +----------------------+-------------------+ 
38. --Vevb.com 
39. | collation_connection | latin1_swedish_ci | 
40.  
41. | collation_database   | utf8_bin          | 
42.  
43. | collation_server     | utf8_bin          | 
44.  
45. +----------------------+-------------------+ 

修改sql文件,代码如下:

1. SET collation_connection = utf8_bin; 
2.  
3. SET character_set_client = utf8; 
4.  
5. 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:

$mysql_mylink = mysql_connect($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:

1. mysql_query("SET NAMES 'UTF8'");  
2. mysql_query("SET CHARACTER SET UTF8");  
3. mysql_query("SET CHARACTER_SET_RESULTS=UTF8'"); 
4. --Vevb.com
