Good point. I was focused on the question of using the alias to restrict

leave it out. In that case, though, the alias question is moot. That
Mike,
I see what you're saying `active` was the alias name not an actual
column. Ironically I was using a HAVING clause because I agree with
that last post.
Mike, why keep the `IF` statement? You're really saying give me all the
records where this expression is true. Why not just move the

have to do the math twice. As was pointed out earlier, he can do what he
wants using HAVING instead of WHERE, like this:
SELECT *,
IF(((unix_timestamp()-unix_timestamp(last_seen)) 600),1,0) active
FROM

SELECT *, IF(( (unix_timestamp()-unix_timestamp(last_seen)) 600),1,0)

I think you'll never be able to do it.
The stuff after the SELECT is
