How to get second largest or third largest entry from a table

Question

Can anyone please tell me how to find out the N th largest entry from a table in Oracle?

Like for largest we can use MAX(column_name) i

Answer 1

SELECT *
FROM (
  SELECT some_column, 
         row_number() over (order by your_sort_column desc) as row_num
  FROM some_table
) t
WHERE row_num = 3

If you expect more than one row to have the same value in your_sort_column you can also use the rank() function

SELECT *
FROM (
  SELECT some_column, 
         rank() over (order by your_sort_column desc) as row_rank
  FROM some_table
) t
WHERE row_rank = 3

This migh return more than one row..
