How to request a random row in SQL?

Currently Using:

$randomQuery = mysql_fetch_row(mysql_query("SELECT * FROM `table` WHERE `id` >= RAND() * (SELECT MAX(`id`) FROM `table`) LIMIT 1"));

Table Structure:

id:
 2 
 4
 5

I want to make sure it’s selecting an existing row. For example, it shouldn’t be able to use 1 or 3 in its randomizing function. Is there a way to do this in MySQL?

Answer 1

I think

SELECT * FROM table ORDER BY RAND() LIMIT 1

would do the trick.
