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...
