Re: Oracle SQL problem... Newbie question

You could try the following:

select decode(awd.item_type, 60, 0, 30, 1, 45, 2, 90, 3, 46, 4, 5), ... from ...
where ...
order by 1;

You'll have one more field and the query will be slower because it will probably not use indexes, but it'll work.

Good luck,
