In the Winter and Summer Olympics of 1988, which game has the most number of competitors? Find the difference of the number of competitors between the two games.
the most number of competitors refer to MAX(COUNT(person_id)); SUBTRACT(COUNT(person_id where games_name = '1988 Summer'), COUNT(person_id where games_name = '1988 Winter'));
SELECT P1 , ( SELECT MAX(P2) - MIN(P2) FROM ( SELECT COUNT(T2.person_id) AS P2 FROM games AS T1 INNER JOIN games_competitor AS T2 ON T1.id = T2.games_id WHERE T1.games_name IN ('1988 Winter', '1988 Summer') GROUP BY T1.season ) ORDER BY P2 DESC LIMIT 1 ) FROM ( SELECT T1.season AS P1, COUNT(T2.person_id) AS P2 FROM games AS T1 INNER JOIN games_competitor AS T2 ON T1.id = T2.games_id WHERE T1.games_name IN ('1988 Winter', '1988 Summer') GROUP BY T1.season ) ORDER BY P2 DESC LIMIT 1
