CREATE TABLE certificate (eid NUMBER, aid NUMBER)
CREATE TABLE aircraft (aid NUMBER, name VARCHAR2, distance NUMBER)
CREATE TABLE employee (eid NUMBER, name VARCHAR2, salary NUMBER)
CREATE TABLE flight (flno NUMBER, origin VARCHAR2, destination VARCHAR2, distance NUMBER, departure_date DATE, arrival_date DATE, price NUMBER, aid NUMBER)

Show me how many destination by destination in a histogram, sort y-axis in ascending order.
SELECT destination, COUNT(destination) FROM flight GROUP BY destination ORDER BY COUNT(destination)
SELECT "destination", COUNT("destination") FROM "flight" GROUP BY "destination" ORDER BY COUNT("destination")
