That's not what it sounds like to me. To me, this sounds like it will only
include those rows that do not have associated rows in sub-tables. That's
not the same as selecting rows without the associated sub-table rows. Kind
of a select * from TS where not exists (any rows in sub-tables of TS)

Looking at it again, it does sound very ambiguous, but I would still lean
(semantically, not using common sense) to what I wrote above. Of course,
common sense would dictate otherwise.
