Doctrine for Subfield in

나는 여러 버스 노선을 다루고있다. 출발점과 목적지 지점에서 가장 가까운 두 점을 가져오고 싶습니다. 그래서 내가하는 일입니다Doctrine for Subfield in

$q = Doctrine_query::create() 
     ->select('r.*') 
//d1 and d2 are the distance between the p1 and p2 points and my dest and depa points. 
     ->addSelect("(6371 * ACOS(SIN(RADIANS($depa_lat)) * SIN(RADIANS(p1.lat)) + COS(RADIANS($depa_lat)) * COS(RADIANS(p1.lat)) * COS(RADIANS(p1.lng) - RADIANS($depa_lng)))) d1") 
     ->addSelect("(6371 * ACOS(SIN(RADIANS($dest_lat)) * SIN(RADIANS(p2.lat)) + COS(RADIANS($dest_lat)) * COS(RADIANS(p2.lat)) * COS(RADIANS(p2.lng) - RADIANS($dest_lng)))) d2") 
     ->from('Route r') 
     ->innerJoin('r.Points p1') 
     ->innerJoin('r.Points p2') 
//this is just to select only the points close enough to my depa and dest point 
     ->andWhere('p1.lat >= ?',$depa_lat - $eps_lat) 
     ->andWhere('p1.lat <= ?',$depa_lat + $eps_lat) 
     ->andWhere('p1.lng >= ?',$depa_lng - $eps_lng) 
     ->andWhere('p1.lng <= ?',$depa_lng + $eps_lng) 
     ->andWhere('p2.lat >= ?',$dest_lat - $eps_lat) 
     ->andWhere('p2.lat <= ?',$dest_lat + $eps_lat) 
     ->andWhere('p2.lng >= ?',$dest_lng - $eps_lng) 
     ->andWhere('p2.lng <= ?',$dest_lng + $eps_lng) 

//those subqueries are to fetch the two closest points, and they seem to be the cause of the crash 
     ->having('d1 = 
     (
      SELECT MIN((6371 * ACOS(SIN(RADIANS('.$depa_lat.')) * SIN(RADIANS(p3.lat)) + COS(RADIANS('.$depa_lat.')) * COS(RADIANS(p3.lat)) * COS(RADIANS(p3.lng) - RADIANS('.$depa_lng.'))))) 
      FROM Point p3 
      WHERE p3.lat >= '.$depa_lat - $eps_lat.' AND p3.lat <= '.$depa_lat + $eps_lat.' AND p3.lng >= '.$depa_lng - $eps_lng.' AND p3.lng <= '.$depa_lng + $eps_lng.' AND p3.route_id = p1.route_id 
     )') 
    ->having('d2 = 
     (
      SELECT MIN((6371 * ACOS(SIN(RADIANS('.$dest_lat.')) * SIN(RADIANS(p4.lat)) + COS(RADIANS('.$dest_lat.')) * COS(RADIANS(p4.lat)) * COS(RADIANS(p4.lng) - RADIANS('.$dest_lng.'))))) 
      FROM Point p4 
      WHERE p4.lat >= '.$dest_lat - $eps_lat.' AND p4.lat <= '.$dest_lat + $eps_lat.' AND p4.lng >= '.$dest_lng - $eps_lng.' AND p4.lng <= '.$dest_lng + $eps_lng.' AND p4.route_id = p2.route_id 
     )') 
     ->orderBy('d1+d2') 
     ->execute();

오류 :이 작업을 수행 할 수있는 더 좋은 방법은

Doctrine_Exception 
Couldn't find class p4

있습니까? 나는 MIN이 GROUP BY와 함께 가야한다고 생각했고, GROUP BY p3.id와 GROUP BY p4.id를 시도했지만 변경되지 않았다.

Symfony의 스택 추적은 다음과 같습니다. parseAggregateFunction() 함수가 쿼리를 지우는 것은 이상한 일입니다. 그렇습니까?

을! 큰. 유일한 것은 doctrine이 "HAVING"을 1 개만 허용한다는 것입니다. 따라서 $ q-> having ('d1 = ('. $ d1-> getDql(). ') AND d2 = ('. $ d2- > getDql(). ')') 또한 -> select ('r. *') 바로 뒤에 하위 쿼리를 만들었습니다. – Julien

Ahhhh ... 잘 잡습니다. Doctrine에 'having'을 사용할 필요가 없어서 좋은 정보를 얻을 수있었습니다! – prodigitalson

Doctrine은 귀하의 독자 또는 다른 독자들에게 유용 할 수있는 추가 기능을 제공합니다 : Doctrine은 [Geographical Behavior] (http://www.doctrine-project.org/projects/orm/1.2/docs/manual/behaviors/en#core- behaviors : geographical) getDistance() 메소드를 제공합니다. – domi27
