[AccessD] An Interesting question

So if I were to ask you what the value of field X is, and field X has
not been set, would you not respond 'Null'?  That makes Null a value.

Drew,

You're wrong.  Null is the absence of a value, indeterminate, not a
selection.  The absence of a value means nothing has been selected, not
that the user has selected a nothing, which is impossible.  The user can
elect to remove an existing value, but that doesn't make the resultant
null a value!  You can't compare anything to Null and the only test you
can make is Is Null.

So black isn't a color? ;)

The absence of a value is still a value... ;)

Is this going to be another great debate?
