Q: 如何导出数据
A:有几种方法，如下：
1、使用mysqldump
#mysqldump -uuser -ppassword -B database --tables table1 --tables table2 > dump_data_20051206.sql
详细的参数

2、backup to语法
mysql>BACKUP TABLE tbl_name[,tbl_name...] TO '/path/to/backup/directory';
详细请查看mysql手册

3、mysqlhotcopy
#mysqlhotcopy db_name [/path/to/new_directory]
或
#mysqlhotcopy db_name_1 ... db_name_n /path/to/new_directory
或
#mysqlhotcopy db_name./regex/
详细请查看mysql手册

4、select into outfile
详细请查看mysql手册

5、客户端命令行
#mysql -uuser -ppassword -e "sql statements" database > result.txt

以上各种方法中，以mysqldump最常用

------------------------------------------------

Q: 如何导入备份出来的文件
A:常见几种方法如下：
1、由mysqldump出来的文件
#mysql -uuser -ppassword [database] < dump.sql

2、文件类型同上，使用source语法
mysql>source /path_to_file/dump.sql;

3、按照一定格式存储的文本文件或csv等文件
