-- write a SQL query to return the top 5 teams, sorted by the total number of hits by players in 2001.
--     Call the column representing total hits by players in 2001 “total hits”.
--     Sort by total hits, highest to lowest.
--     Your query should return two columns, one for the teams’ names and one for their total hits in 2001.
SELECT
    t."name",
    SUM(perf."H") AS "total hits"
FROM "teams" AS t
JOIN "performances" AS perf
    ON perf."team_id" = t."id"
WHERE perf."year" = '2001'
GROUP BY t."id", t."name"
ORDER BY "total hits" DESC
LIMIT 5;
