CREATE TABLE track (track_id NUMBER, name CLOB, location CLOB, seating NUMBER, year_opened NUMBER)
CREATE TABLE race (race_id NUMBER, name CLOB, class CLOB, date CLOB, track_id CLOB)

What are the years of opening for tracks with seating between 4000 and 5000?
SELECT year_opened FROM track WHERE seating BETWEEN 4000 AND 5000
SELECT "year_opened" FROM "track" WHERE "seating" <= 5000 AND "seating" >= 4000
