I am sorry you think I'm trolling. I'm serious.
Special Values like "Not Available" or "Inapplicable" are really not
values, if you think about them.
Adding them to the domain is just a perverse use of the domain. It's a
kludge.
If there is a NULL bit for every cell, as there should be in a good RDBMS,
it should be set to NULL
in the cases listed above.
Calling "Not Available" a value doesn't make it so. Calling this comment a troll doesn't make it so. Received on Mon Apr 26 2004 - 13:55:50 CEST
