this is my query :

        ->select()
        ->where('up.user = :user')
        ->andWhere('SUM(prize.prizeValue) <= :price')
        ->setParameters(['user'=>$user , 'price'=>$price])
        ->getQuery()
        ->getResult();
    return $qb;

Answer 1

您不能在WHERE子句中使用聚合函数。

Why are aggregate functions not allowed in where clause

尝试一下：

$qb = $this->createQueryBuilder('up')
        ->join('up.prize','prize')
        ->select('up')
        ->where('up.user = :user')
        ->having('SUM(prize.prizeValue) <= :price') // Replace with `having`
        ->setParameters(['user'=>$user , 'price'=>$price])
        ->groupBy('up') // `Group by` because you're using an aggregate
        ->getQuery()
        ->getResult();
    return $qb;

Answer 2

您必须将位置条件移到 HAVING 子句

$qb = $this->createQueryBuilder('up')
        ->join('up.prize','prize')
        ->where('up.user = :user')
        ->having('SUM(prize.prizeValue) <= :price')
        ->groupBy('up.id')
        ->setMaxResults(5);
        ->setParameters(['user'=>$user , 'price'=>$price]);

    return $qb->getQuery()->getResult();
