Hi Danisment Gazi Unal,
Itprof's suggestion is valid that I should be able to
use an index to speed up this query.
But my objective here is to help sorting. Many users
write adhoc queries to into my warehouse and all are
not going to be tuned queries. Many go for full
tablescans on some big fact tables and sort like
hell.
We do have some good indexes for often used queries.
But it is the adhoc one which people cook up that hurt
us bad.
So my intention is to tune sorts. In that light could
you give me an explanation for the query running slow
because the sort_area_size was increased?
