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

What is the name of the track that has had the greatest number of races?
SELECT T2.name FROM race AS T1 JOIN track AS T2 ON T1.track_id = T2.track_id GROUP BY T1.track_id ORDER BY COUNT(*) DESC LIMIT 1
SELECT "T2"."name" FROM "race" "T1" JOIN "track" "T2" ON "T1"."track_id" = "T2"."track_id" GROUP BY "T1"."track_id" ORDER BY COUNT(*) DESC FETCH FIRST 1 ROWS ONLY
