OK, TODO updated:
* Allow an alias to be provided for the target table in UPDATE/DELETE
This is not SQL-spec but many DBMSs allow it.
* Allow additional tables to be specified in DELETE for joins
UPDATE already allows this (UPDATE...FROM) but we need similar functionality in DELETE. It's been agreed that the
keywordshould be USING, to avoid anything as confusing as DELETE FROM a FROM b.
