Order in CREATE VIEW

hello everybody,
Can you help me?

I have POSTGRESQL 7.0.3,
I try to create simple view by typing.

create view "xx" as select "aa.yy", "bb.yy" from "yy" order by "bb.yy"

the problem is that parameter order is not implemented with create view.
so how can I create such simple query??

Best regards
Marcin
