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)
CREATE TABLE certificate (eid NUMBER, aid NUMBER)

Give me a pie to show the total number from different origin.
SELECT origin, COUNT(*) FROM flight GROUP BY origin
SELECT "origin", COUNT(*) FROM "flight" GROUP BY "origin"
