Didn't have to UNNEST the participants or splits fields after using a cross join. Example (Task 8): #standardSQL SELECT p.name, SUM(split_times) as total_race_time FROM racing.race_results AS r , r.participants AS p , p.splits AS split_times WHERE p.name LIKE 'R%' GROUP BY p.name ORDER BY total_race_time ASC ;
