Hi abbas,

Thank you so much.  I've got this query from my development team asking to
improve its performance. 

Now I got pretty much clear idea of it. And it will be the final extent to
which we can tune the performance right?

If there is still a way give me some tips to enhance the query performance. 

But kudos for your "floor" function. After a long struggle with the indexes,
joins and the hints I came to know that there is also a way to tune the
query performance by rewriting the query.

Thanks in advance.

Regards,
Pavan
