that is what i want to avoid. (i wrote that in my first mail)
My question was about why it is not possible to do it like this:
....ORDER BY $1
I don't know if it is standards-conform or if someone considers it a usefull
feature, but i think it would help users to write capsulated
statistics-functions or simply browsable and orderable lists.
