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

You can find the Nth largest value of a column by using the following query

SELECT * 
FROM TableName a 
WHERE n = (
           SELECT count( DISTINCT (b.ColumnName) )
           FROM TableName b 
           WHERE a.ColumnName <= b.ColumnName 
          );
