have a look at the HAVING clause:
mysql> SELECT user,MAX(salary) AS sum FROM users
-> group by user HAVING sum>10;

> Okay, I thought I'd done this before but maybe not. I can't figure it

> What I want to do is:
>
> SELECT column AS something FROM table WHERE something > 5
>
> Basically I'm creating a new column called something and I want to use
> it to compare with in the WHERE condition. Is this possible?
>
> Ultimately I want to have MySQL calculate the age of people and also put
> a condition on it. I am using a very old fashioned web language which
> doesn't have a lot of power. I could do this in PHP if I could only use
> it. But I need MySQL to do it.

> Any thoughts?

> Also what is the name of this that I am doing, creating a new column.
> Is it a "dynamic" column or something?
