CREATE TABLE certificate (eid DECIMAL, aid DECIMAL)
CREATE TABLE flight (flno DECIMAL, origin VARCHAR, destination VARCHAR, distance DECIMAL, departure_date DATE, arrival_date DATE, price DECIMAL, aid DECIMAL)
CREATE TABLE aircraft (aid DECIMAL, name VARCHAR, distance DECIMAL)
CREATE TABLE employee (eid DECIMAL, name VARCHAR, salary DECIMAL)

Show me how many destination by destination in a histogram, order bars in descending order.
SELECT destination, COUNT(destination) FROM flight GROUP BY destination ORDER BY destination DESC
SELECT "destination", COUNT("destination") FROM "flight" GROUP BY "destination" ORDER BY "destination" DESC NULLS LAST
