In general, to do that in a UI (web , IDE, etc), you would need both an
entry field and a checkbox to make the difference between "" and the
null value, which I've seen very very rarely...Are we ready to add this
check box for all possible fields? or rely on default common sense?
Sometimes, Apps used so special string for entering a null value (like
(null)) but this means that the "(null)" string would never be a
possible user value.
