How about:
select distinct ename,job,sal
from ( select ename,job,sal
from ( select * from emp order by salary desc )
where rownum <= 10000000
);
Uses a lot of temp tablespace, though, and will not be very fast for large
tables ... you should probably try one of the new functions of Oracle 8(i?).
What verion do you use ?

Hi List
I have a question regarding a SQL query I am working on.
I have a table named 'tmp_scores', with a column 'rank' and other columns.
Rank varies from 1 to 12. I need to get the top 10 million records based on
the rank.
I have used the logic behind the following query(to get top 4 salaried
employees)
-----
select ename,job,sal from emp e
where 4 > (select count(*) from emp
where e.sal<sal)
order by sal;
-----
to get my task accomplished as below:
SELECT a.customer_id,
a.first_name,
a.last_name,
a.carrier_route_code,
a.unit_designator||'|'||a.street_pre_directional||'|'||
a.primary_street_number||'|'||a.primary_street_name||'|'||
a.street_post_directional||'|'||a.secondary_address_number||'|'||
a.secondary_address_name "Street",
city,
a.state_code,
a.postal_code,
a.postal_code_extension,
a.combined_score_demi_decil_rank
FROM tmp_stg_van_customer_details a
WHERE 10000000 > = (SELECT count(*) FROM
tmp_stg_van_customer_details
WHERE a.combined_score_demi_decil_rank <
combined_score_demi_decil_rank)
ORDER BY combined_score_demi_decil_rank;
I have issued the query and it has been running for the last three days
without giving any error.
I am not able to conclude what to do.
Any help is highly appreciated.
Thanks in advance.
