How to find from a source which has 10,000 records, find the
average between 500th to 600th record?
Answer Posted / sudhar
Your answer is correct for the flat files. But the RElation
query you have given won't give any records.
the Query should like this
select avg(sal) from
(select emp_id, sal, rownum rnum from (
select emp_id,sal from emp order by sal desc) )where rnum
between 500 and 600
Might be this Query can be simplified with Rank option in
Oracle.
