I needed to copy a database and the idea of backing it up just to re-import1 seemed like double the work. Here’s a snippet to pipe a mysqldump into a remote database. Keep an eye on the user names and passwords – you’ll need 3 sets; one for the database your copying, one to get into your remote server, and one for the remote, target database.
mysqldump -v -uUSER -pPASSWORD --opt --compress DATABASE_NAME | ssh REMOTE_SERVER_USER@REMOTE_HOSTNAME mysql -uREMOTE-MYSQL-USER -pREMOTE_MYSQL_PASSWORD REMOTE_DATABASE_NAME
1. Backing up is a good thing. Why aren’t you doing it? Here’s a script for that.
mysqldump -h HOSTNAME DATABASE_NAME | gzip -9 > BACKUP_DIR/DATABASE_NAME.sql.gz
