Retrieve third lowest value from a table


Retrieve third lowest value from a table


Question: How can I retrieve the third lowest salary amount from a salary table?

Answer: To retrieve the third lowest salary from a salary table, you could run the following query: (please note that the subquery is sorted in ascending order)
SELECT salary_amount
FROM(select salary2.*, rownum rnum from
(select * from salary ORDER BY salary_amount) salary2
where rownum <= 3 )
WHERE rnum >= 3;

If you wanted to retrieve all fields from the salary table for the third lowest salary, you could run the following query: (please note that the subquery is sorted in ascending order)
SELECT *
FROM(select salary2.*, rownum rnum from
(select * from salary ORDER BY salary_amount) salary2
where rownum <= 3 )
WHERE rnum >= 3;
