To export

导出指定db_name的数据：

$ mysqldump -u [uname] -p[pass] db_name > db_backup.sql

导出整个库的数据：

$ mysqldump -u [uname] -p[pass] --all-databases > all_db_backup.sql

导出指定表的数据

$ mysqldump -u [uname] -p[pass] db_name table1 table2 > table_backup.sql

导出打包的数据文件（如果文件很大）

$ mysqldump -u [uname] -p[pass] db_name | gzip > db_backup.sql.gz

导出远程机器上的数据：

$ mysqldump -P 3306 -h [ip_address] -u [uname] -p[pass] db_name > db_backup.sql

如果只导出sql语句，不需要数据，可加参数 --no-data

To import

Type the following command to import sql data file:

$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql

In this example, import ‘data.sql‘ file into ‘blog‘ database using Sathish as username:

$ mysql -u sat -p -h localhost blog < data.sql

If you have a dedicated database server, replace localhost hostname with with actual server name or IP address as follows:

$ mysql -u username -p -h 202.54.1.10 databasename < data.sql

OR use hostname such as mysql.cyberciti.biz

$ mysql -u username -p -h mysql.cyberciti.biz database-name < data.sql

If you do not know the database name or database name is included in sql dump you can try out something as follows:

$ mysql -u username -p -h 202.54.1.10 < data.sql
