將 SQL 查詢轉換為 Doctrine DQL（加入和分組依據）

Question

我需要將 SQL 查詢轉換為 Doctrine DQL。

SELECT g.id, g.round_id, g.score, g.prize_id
FROM game g
INNER JOIN (
    SELECT prize_id, MAX(score) score
    FROM game
    GROUP BY prize_id
) g2 
ON g.prize_id = g2.prize_id AND g.score = g2.score
ORDER BY prize_id DESC

怎么做？

Answer 1

我已經找到了如何在 Doctrine DQL 中做到這一點：

return $this->createQueryBuilder('g')
    ->leftJoin('App\Entity\Quizz\Game', 'g2', 'WITH', 'g.prize = g2.prize AND g.score < g2.score')
    ->andWhere('g2.prize IS NULL')
    ->getQuery()
    ->getArrayResult();
