Question

可能重复：
got a select that does 10 query in doctrine (Symfony)

我目前在我的symfony应用程序中遇到了一个大问题，我有一个复杂的SQL查询，它使数据库连接过多。

查询顺序，使用doctrine searchable搜索关键字，并检查地理位置。

这里粘贴完整的模型和sql日志，任何人都知道我做错了什么？：/

public function getListItems($orderby, $budget, $motscles, $userid, $catID, $useDistance = true)
{

   // CHANGE ORDER 
   if(!$orderby){
     $orderby = "a.created_at DESC";
   }else if($orderby == "price"){
     $orderby = "a.price ASC";
   }else if($orderby == "date") {
     $orderby = "a.created_at DESC";
    }else{
     $orderby = "a.created_at DESC";
   }

   // Search Keywords in table
   if($motscles){
    $searchItem = Doctrine_Core::getTable('csw_Article');
    $results = $searchItem->search($motscles);
    $ids = array();

    foreach ($results as $result) {

        $ids[] = $result['id'];
    }
    if(sizeof($ids) == 0){
      $ids[] = 0;
    }
   }        
    $q = Doctrine_Core::getTable('csw_Article')
        ->createQuery("a")
        ->leftJoin('a.csw_CategorieArticle ca');

    $sfContext = sfContext::getInstance()->getUser();

    if($useDistance){
        $lat = (string)($sfContext->getAttribute('userLat')) ? $sfContext->getAttribute('userLat') : sfConfig::get("app_user_lat");
       $long = (string)($sfContext->getAttribute('userLong')) ? $sfContext->getAttribute('userLong') : sfConfig::get("app_user_long");  
        $radius = 18;
        $q->select("a.longitude, a.latitude, (3959 * acos(cos(radians('".$lat."')) * cos(radians(latitude)) * cos(radians(longitude) - radians('".$long."')) + sin(radians('".$lat."')) * sin(radians(latitude)))) AS distance");
        $q->having("distance < ?", $radius);
    }
    if($orderby == "distance") {            
        $q->orderBy("distance desc");   
    }               
        $q->addOrderBy($orderby);

     if($catID){
       $q->where('ca.categorie_id = ?', $catID);
     }
     if($budget != 0){

      $budget_min = $budget - ($budget * 0.20);
      $budget_max = $budget + ($budget * 0.20);
      $q->addwhere('a.price > ?',$budget_min)
        ->addwhere('a.price < ?',$budget_max);
     }  
     if($userid){
       $q->addwhere('a.userid = ?', $userid);
     }


     if($motscles){
       $q->whereIn('a.id', $ids);

     }        
     $q->execute();      
     return $q;
}

Answer 1

您可以启用xdebug_loggin来查找查询的来源：

//factories.yml
    dev:
      logger:
        param:
          loggers:
            sf_web_debug:
              param:
                xdebug_logging: true

这会将跟踪记录到每个查询中，并且应该为您提供出错的线索

Answer 2

我认为问题不在于您是如何进行查询的，而是如何在操作或视图中使用它。我想你正在做的事情如下：

foreach($items as $item){
   $model->getListItems(...);
}

因此每个$ item都会有一次db调用。在按用户过滤时尝试使用WhereIn而不是addWhere。

Symfony 1.4为1个查询提出15个DB请求
