Sure, I did understand that. But I think it is quite pointless
to burden the db or the app with such functionality.
Just to have random ordered columns which do not correspondent
to any physical ordering by the db.
So it does not influence query performance to arrange the
selected columns this or that order. So why confusing
the user by pretending it has any meaning to order the columns?

I think there are quite more praxis relevant problems to solve :)

Tino
