How to import and export mysql using ssh

Yesterday I have problem about import mysql using mysql.. so I googling and get solution about export and import mysql using ssh over putty.

If you want to export mysql, you can using this command : mysqldump -u username -p database_name > dumpfile.sql

For import :
mysql -u username -p database_name < dumpfile.sql

If file .sql very big, you can upload first this file using ftp..
Great lol I writing in English :D
