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

How many flights with price higher than 300 for each destination city? Return a bar chart, I want to show X-axis from high to low order.
SELECT destination, COUNT(destination) FROM flight WHERE price > 300 GROUP BY destination ORDER BY destination DESC
SELECT "destination", COUNT("destination") FROM "flight" WHERE "price" > 300 GROUP BY "destination" ORDER BY "destination" DESC
