Copy an entire database:
mysqldump LOCAL_DBNAME | ssh USER@REMOTE_HOST mysql -p REMOTE_DBNAME
Copy a single table:
mysqldump LOCAL_DBNAME LOCAL_TABLE | ssh USER@REMOTE_HOST -p REMOTE_DBNAME REMOTE_TABLE
This shortcut only works if you can access the local DB without a password. If you have to login to both local and remote MySQL servers, the MySQL password prompts get mashed together. You could specify the password on the command line like
-pPASSWORD
but your shell may keep the password in its history so that anyone with access to your account could pick through your shell history and retrieve the password. Using the MySQL password prompt doesn’t do this.
