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

Return a bar chart on what are the names and distances for all airplanes?, and I want to sort names from low to high order.
SELECT name, distance FROM aircraft ORDER BY name
SELECT "name", "distance" FROM "aircraft" ORDER BY "name" NULLS FIRST
