CREATE TABLE captain (Captain_ID NUMBER, Name CLOB, Ship_ID NUMBER, age CLOB, Class CLOB, Rank CLOB)
CREATE TABLE Ship (Ship_ID NUMBER, Name CLOB, Type CLOB, Built_Year FLOAT, Class CLOB, Flag CLOB)

Show me a bar chart comparing the total number of captains of different classes, and rank by the Class from low to high.
SELECT Class, COUNT(Class) FROM captain GROUP BY Class ORDER BY Class
SELECT "Class", COUNT("Class") FROM "captain" GROUP BY "Class" ORDER BY "Class"
