  • @MTilsted: no it's not. It's the absence of a value. Commented Feb 24, 2014 at 12:27

    @a_horse_with_no_name:- Yes very correct. Or better to say Unknown value as OP can misinterpret it and may think that it is the same as empty ;) Commented Feb 24, 2014 at 12:29
  • NULL is a value used to indicate that there is no domain specific value in the field. But I would still say that NULL itself is a value. Just try to ask a database admin what the default value is of a field, if no value is provided. And he will most likely answer null. Commented Feb 24, 2014 at 13:58
