Я пытаюсь вернуть всю страну, в которой есть футбол matches
, который играет в определенном date
. Данные определены в следующих таблицах:
Конкурс
id | country_id | name
50 1 Premier League
competition_seasons
id | competition_id | name
70 50 2019
competition_rounds
id | season_id | name
58 70 Regular Season
матч
id | round_id | home | away | result | datetime
44 58 22 87 1 - 0 2019-03-16:00:00
В таблице competition
хранятся различные соревнования, и тогда каждое соревнование может иметь несколько season
, которые хранятся в competition_seasons
. season
также может иметь различную конкуренцию rounds
, они хранятся в competition_rounds
.
Все matches
хранятся в таблице match
и группируются по round_id
.
Я написал этот метод для API:
$app->get('/country/get_countries/{date}', function (Request $request, Response $response, array $args)
{
$start_date = $args["date"] . " 00:00";
$end_date = $args["date"] . " 23:59";
$sql = $this->db->query("SELECT n.* FROM country n
LEFT JOIN competition c ON c.country_id = n.id
LEFT JOIN competition_seasons s ON s.competition_id = c.id
LEFT JOIN competition_rounds r ON r.season_id = s.id
LEFT JOIN `match` m ON m.round_id = r.id
WHERE m.datetime BETWEEN '" . $start_date . "' AND '" . $end_date . "'
GROUP BY n.id");
$sql->execute();
$countries = $sql->fetchAll();
return $response->withJson($countries);
});
существуют тысячи записей, организованных по идентификатору, но запросу потребовалось около 6,7 секунды, чтобы вернуть все countries
, которые воспроизводятся в указанную дату.
Как я могу оптимизировать этот процесс?
Производительность
UPDATE
Я заметил интересную вещь, если я сделаю:
SELECT round_id, DATE("2019-03-18") FROM `match`
запрос действительно быстрый, так что я думаю, поле datetime
замедляет процесс соединения, есть идеи?
