CREATE TABLE actor (Actor_ID NUMBER, Name CLOB, Musical_ID NUMBER, Character CLOB, Duration CLOB, age NUMBER)
CREATE TABLE musical (Musical_ID NUMBER, Name CLOB, Year NUMBER, Award CLOB, Category CLOB, Nominee CLOB, Result CLOB)

Group and count the durations for each actor with a bar graph, and I want to rank Y-axis in desc order.
SELECT Duration, COUNT(Duration) FROM actor GROUP BY Duration ORDER BY COUNT(Duration) DESC
SELECT "Duration", COUNT("Duration") FROM "actor" GROUP BY "Duration" ORDER BY COUNT("Duration") DESC
