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

What are the destinations and number of flights to each one Visualize by bar chart, and I want to display in desc by the x axis.
SELECT destination, COUNT(*) FROM flight GROUP BY destination ORDER BY destination DESC
SELECT "destination", COUNT(*) FROM "flight" GROUP BY "destination" ORDER BY "destination" DESC
