I guess it should have also work. But I was thinking that Sergey's solution is probably more efficient since it doesn't involve a JOIN.

It's actually very nice to use select * from (select...), I don't see this syntax suggested here often.

But just for curiosity sake I would appreciate if you can try both approaches and may be even compare the speed.
