FROM `resturant`
LEFT JOIN `food`
    ON `resturant`.`id` = `food`.`resturant_id`

GROUP BY `resturant`.`name`

Answer 1

假设您的Restaurant实体通过属性Food与$foods实体相关联：

$this->createQueryBuilder('restaurant')
    ->leftJoin('restaurant.foods', 'food')
    ->where('food.name LIKE %pizza%')
    ->groupBy('restaurant.name')
    ->getQuery()->getResult();
