Why not:

Select * from (

	Select id, rownum rn 
		from emp_dtl 
		where 1 = 1 AND Group='WHO' 
		and Cust_acct='GE' and Update_tag = 'F' and
Category_code=1 		order by Acct_num, seq_number )
	where rn >= 50
	and rn < 100;

btw., what's oracle version?

I had query  

select * from

(select inner.*, rownum rn from

(select ID from emp_dtl where 1 = 1 AND Group='WHO' and Cust_acct='GE'
and Update_tag = 'F' and Category_code=1 order by Acct_num, seq_number )inner

 where rownum < 100)

where rn >= 50  

The Inner Portion run in few second , while the reamining query takes ages like 40-45minutes. Any idea as what I am missing or any optimization.  

TIA Sanjay
