combine "union" and "order by "

How can combine union with order by together?

I tried the simple query, it works

select channel_id, null, null from channel where channel_id < 6501
union
SELECT channel_id, stream_id, null from stream where channel_id < 6501
order by channel_id

but the complex one doesn't work (It shows ch.cahnnel_id is invalid indentifier)

Any comments??
