Selecting Random Result from MySQL

Question

I wanted to randomly select results from mysql database with this code:

$data = mysql_query("SELECT * FROM people ORDER BY RANDOM() LIMIT 4") or die(mysql_error()); 

I got an error message: FUNCTION members.RANDOM does not exist

Is there something I'm not adding or doing right here?

Thanks for your asistance.
