Correct me if I'm wrong, but ORDER BY shoud not be part of a view, in the
same way it is not a part of a table. A table is defined as an unordered
collection of tuples. In any given query, you can define the order of the
tuples returned. But the table itself is not ordered.
A view should look to the user just like a table. The order of the tuples
is part of the query, not part of the table, and not part of the view.
