Find the nth Maximum and Minimum Values in a Given Column

This SQL code retrieves the nth Maximum and nth Minimum values in the column specified in <COLUMNNAME> from the table <TABLENAME>.

The argument will be accepted in the runtime by SQL:

To find the Nth Max:


SELECT * FROM  <TABLENAME> a WHERE  &N = (SELECT count(DISTINCT
(b.<COLUMNNAME>)) FROM <TABLENAME> b WHERE
a.<COLUMNNAME><=b.<COLUMNNAME>);
To find the Nth Min

SELECT * FROM  <TABLENAME> a WHERE  &N = (SELECT count(DISTINCT
(b.<COLUMNNAME>)) FROM <TABLENAME> b WHERE
a.<COLUMNNAME>>=b.<COLUMNNAME>);
