contributions to the above threads are "good" as opposed to "bad"
(unreasonable, misleading, containing bad advice) ... If I want to say
that your contribution is good I'd put a "true". If I am in doubts or
have mixed feelings, I don't want to pronounce, I won't insert
anything. ... Voila: a natural usage of boolean datatype, *and* there
are no NULLs in the table, and no NULLs are ever needed in this case

You never worked as a statistician! You need a subjective preference scale that has either 5 or 7 steps ("walks on water" to "sucks rocks") in the scale for this kind of task. More values in the scale and the results are not reproducible; fewer values and the test instrument is not usable :) Received on Sun Apr 13 2003 - 01:40:48 CEST
