CREATE TABLE PersonFriend (name VARCHAR2, friend VARCHAR2, year NUMBER)
CREATE TABLE Person (name VARCHAR2, age NUMBER, city CLOB, gender CLOB, job CLOB)

How old is the youngest person for each job Visualize by bar chart, and I want to rank by the minimal age from high to low.
SELECT job, MIN(age) FROM Person GROUP BY job ORDER BY MIN(age) DESC
SELECT "job", MIN("age") FROM "Person" GROUP BY "job" ORDER BY MIN("age") DESC
