This is simple,
consult your manual about crontab.
and start a script like that:
mysql -BAN database <<EOF
place my great sql-statemant here ....
If you need some additional informationen like $HOME
you can use it also
If something goes wrong a mail will be send to the owner (details
see man 5 crontab)
