Oracle's conversion of '' to NULL is a well-known problem.

Of course, other systems (Sybase for example) convert '' to ' ' (i.e. a single space) if the value is a varchar() - essentially because a zero length string is considered the same thing as NULL.

I'm pretty sure that this behavior (i.e. inability to store a zero length string) is mandated by the SQL standard. In any case it's been discussed to death on the dbi-users mailing list, and in other lists/newsgroups as well.
