DQL查詢獲取地理空間點st_within一個矩形

Question

我想編寫DQL查詢來選擇地圖中矩形內的所有點。矩形由左上角和右下角定義。有關更多詳細信息，請參閱此link。

要做到這一點，我寫了這個DQL查詢：

$qb = $this->em->createQueryBuilder() 
    ->select("m") 
    ->from($this->getEntityClassName(), "m") 
    ->where("ST_Within(m.geom, envelope(linestring(:topleft, :bottomright)))") 
    ->setParameter(":topleft", $topleft) 
    ->setParameter(":bottomright", $bottomright) 
    ->orderBy("m.date", "DESC"); 

我得到的錯誤是：

[Syntax Error] line 0, col 110: Error: Expected =, <, <=, <>, >, >=, !=, got 'ORDER' 

爲了您的信息，實體我詢問有GEOM屬性定義如下： ：

/** 
* @var point $geom 
* @ORM\Column(type="point", nullable=true) 
*/ 
protected $geom; 

有關您的信息，SQL查詢工作正常。這是因爲如下：

SELECT *FROM MotorsAds WHERE 
st_within(point(lng, lat),   
envelope(linestring(point(10.090792984008772,36.83717099338201), 
point(10.310519546508772,36.749467295867646)))) 

我使用DQL數字功能（例如我們st_within）圖書館是creof/doctrine2-spatial。

準備採取任何建議來解決這個問題。

感謝，

更新問題

我想你提出的解決方案如下：

$qb = $this->em->createQueryBuilder() 
     ->select("m") 
     ->from($this->getEntityClassName(), "m") 
     ->where(
      $this->em->createQueryBuilder()->expr()->eq(
        "ST_Within(m.geom, envelope(linestring(:topleft, :bottomright)))", 
        $this->em->createQueryBuilder()->expr()->literal(true) 
       ) 
     ) 
     ->setParameter(":topleft", $topleft) 
     ->setParameter(":bottomright", $bottomright) 
     ->orderBy("m.date", "DESC"); 

所以，我得到的錯誤是：

執行'SELECT COUNT（*）AS dctrn_count FRO時發生異常M SELECT_DISTINCT_ID_0 FROM（SELECT m0_.id AS_id_0，m0_.price AS price_1，m0_.year AS year_2，m0_.km AS km_3，m0_.slug AS slug_4，m0_.title AS title_5，m0_.description AS description_6， m0_.address AS address_7，m0_.isPublished AS isPublished_8，m0_.delegation AS delegation_9，m0_.lat AS lat_10，m0_.lng AS lng_11，m0_.date AS date_12，m0_.count AS count_13，AsBinary（m0_.geom）AS geom_14 FROM MotorsAds m0_ WHERE ST_Within（？m0_.geom，包絡（線段形式（?,）））= 1個ORDER BY m0_.date DESC）dctrn_result）dctrn_table」使用參數[{}，{}]：

下面的解決方案會阻止您轉換的問題PHP點DQL查詢點。

$qb = $this->em->createQueryBuilder() 
     ->select("m") 
     ->from($this->getEntityClassName(), "m") 
     ->where(
      $this->em->createQueryBuilder()->expr()->eq(
        sprintf("ST_Within(m.geom, envelope(linestring(point(:topleftX,:topleftY), point(:bottomrightX,:bottomrightY))))"), 
        $this->em->createQueryBuilder()->expr()->literal(true) 
       ) 
     ) 
     ->setParameter(":topleftX", $topleftX) 
     ->setParameter(":topleftY", $topleftY) 
     ->setParameter(":bottomrightX", $bottomrightX) 
     ->setParameter(":bottomrightY", $bottomrightY) 
     ->orderBy("m.date", "DESC"); 

Answer 2

嘗試t他：

$qb = $this->em->createQueryBuilder() 
    ->select("m") 
    ->from($this->getEntityClassName(), "m") 
    ->where(
     $queryBuilder->expr()->eq(
       "ST_Within(m.geom, envelope(linestring(:topleft, :bottomright)))", 
       $queryBuilder->expr()->literal(true) 
      ) 
    ) 
    ->setParameter(":topleft", $topleft) 
    ->setParameter(":bottomright", $bottomright) 
    ->orderBy("m.date", "DESC");
