Dunno, but I know that other databases (at least DB2) don't require FROM
either. In Oracle, if you want to do something like
SELECT now();
you actually have to do
SELECT now() FROM dual;
where dual is a special, hard-coded table in Oracle that has only one
row. Personally, I find their approach to be pretty stupid.
