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

Draw a bar chart for what is minimum age for different job title?, and could you display by the X-axis from high to low?
SELECT job, MIN(age) FROM Person GROUP BY job ORDER BY job DESC
SELECT "job", MIN("age") FROM "Person" GROUP BY "job" ORDER BY "job" DESC
