Triggering an action every 24 hours

[Samuel Vogel]

Hey,

I am wondering how I can trigger an Action every 24 hours inside of mysql.
A cron job would also do the job, but it won't work on shared hosts and 
it's just another point of failure.

So is there any way to run a specific SQL command every 24 hours inside 
of mysql?
I'm using MySQL 5.0.51!

Regards,
Samy
