I wasn't sure why "" should not be the same as null, but your post gave me the answer:

If I am inserting a varchar into a DB and I have a null pointer (empty string), what do I insert, "" or NULL? That is an important difference (unless you are using MySQL, that is).

Would a solution be that an empty string is not null but has zero length?
