恢复数据库报错：由于字符集问题，最原始的数据库默认编码是latin1，新备份的数据库的编码是utf8，因此导致恢复错误。
[root@hk byrd]# /usr/local/mysql/bin/mysql -uroot -p"admin" t4x < /tmp/11x-B-2014-06-18.sql
ERROR 1064 (42000) at line 292: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ""[caption id=\"attachment_271\" align=\"aligncenter\" width=\"300\"]
修复方法(未实测)：

其他的一些设置方法：
修改数据库的字符集
mysql>use mydb
mysql>alter database mydb character set utf-8;
创建数据库指定数据库的字符集
mysql>create database mydb character set utf-8;
通过配置文件修改:
修改/var/lib/mysql/mydb/db.opt
default-character-set=latin1
default-collation=latin1_swedish_ci
为
default-character-set=utf8
default-collation=utf8_general_ci
重起MySQL:
[root@bogon ~]# /etc/rc.d/init.d/mysql restart
通过MySQL命令行修改:
mysql> set character_set_client=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_connection=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_database=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_results=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_server=utf8;
Query OK, 0 rows affected (0.00 sec)
mysql> set character_set_system=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_connection=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_database=utf8;
Query OK, 0 rows affected (0.01 sec)
mysql> set collation_server=utf8;
Query OK, 0 rows affected (0.01 sec)
查看:
