Joe may have a point, even if did not hit the nail perfectly. Up to
SQL 6.5, there wasn't any deferred name resolution, so something like:

CREATE VIEW innerview AS SELECT 12 AS gurka
CREATE VIEW outerview AS SELECT gurka FROM innerview

would fail at compilation. For tables there were some special plumbing
to permit you to create a table and refer to it in the same batch, but
I guess they never found that worthwhile for views.
