I don't know enough about SQL to know how its  NULL compares to Perl's undef, but it strikes me that "I know what the value is, and the value is: that it is known that it has no value at all" is actually a pretty good (Update: well, on second thought, perhaps just a bit wordy) explanation of our friend undef!
