If it's nullable, then it can't be a boolean.

I'm sure that a subject of such import must have been discussed here before, but if so, I missed it. If it can have more than two values it cannot really be a boolean value, so why call it a nullable bool? Anyone got a better name? I can only come up with truelean or trilean.

In Spanish a "trilero" is a guy who use three cards or pots to hide a small ball to cheat tourists in crowded streets... so avoid that name... if you don't avoid it one of your variables could go to jail... :rolleyes:

In "The Relational Model of Database Management v2" (a tome and a half), Codd introduces 4-valued logic, Yes, No, Maybe but Applicable, Maybe and Inapplicable. The distinction between the latter affects how aggregates apply (you can Count Applicable (or A-Marks), but not Inapplicable (I-Marks)). Unfortunately, by Codd's definitions, there are No RDBMS in existence. (There are many other improvements there, we would probably have no need for ORM's among other things). Doesn't answer your question of course ;-)

a "nullable boolean" is equivalent to "pointer-to-boolean", if it's null then you don't know the answer.
