But is there a way to achieve one row output with both the count() and
its selector, when the ocunt is ZERO?

I'm digging this, because it looke like I need a VIEW, that returns such
count() no matter what. And in fact the selector (which is coming from
subquery) is more important for me in that case, than the count() itself
(well, I need to distinquish zero from something, but nothing more).

Is there a way to see it?
