Hello,
It strikes me as odd that the BOOLEAN data type is not a core requirement in SQL:1999 while so many other esoteric features are.
Am I right in that it looks like SQL:200n will keep BOOLEAN out of the core?
I personally find boolean data types useful in many situations. What do the SQL standards-people dislike about the BOOLEAN type?
Anyways:
_When_ it's implemented, it's not clear to me which domain the type has.
Are all the following values allowed?:
true
false
unknown
null
Does null equal unknown?
