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

Show me how many destination by destination in a histogram, and order y-axis in desc order.
SELECT destination, COUNT(destination) FROM flight GROUP BY destination ORDER BY COUNT(destination) DESC
SELECT "destination", COUNT("destination") FROM "flight" GROUP BY "destination" ORDER BY COUNT("destination") DESC NULLS LAST
