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.
