How to import/export database using MySql command line
Sometimes when you have large databases, phpmyadmin or similar tool might fall when it comes to exporting or importing. The easiest (and fastest) way is to use command line.
To export use this command:
mysqldump -u USER -p PASSWORD DATABASE > filename.sql
To import database from dump file (in this case called filename.sql) use:
mysql -u username -p password database_name < filename.sql
