Order clause conditioned by value

Thanks AndyH,
I made the changes in the order clause but no change in the query.
I think the problem is when is evaluation each order and even with the indexes created takes a lot of time.
Thanks again!!

No problem! Did you create descending indexes to match the UPDATED and NEWFIRST sort orders? Also, you might need a function-based index to deal with your NAME sort.
You don't mention how big the report is that you return, if it's large then sorting may be occurring on disk and that will be slow.
It would be interesting to see explain plan for your queries.

I can't see any sort options in the given SQL.
I'd guess that the database has decided that there are no advantages to using the indexes for sorting, possibly given the number of rows returned compared to the overall rowset. Also, the indexes are often only used when requesting a 'first rows' result set.
