Laravel查詢生成器 - 用特殊的數據類型

Question

查詢我有一個表像這個 -

所以，我有user_location一個特殊的數據類型（POINT）。

的RAW選擇查詢就像是這個 -

SELECT 
    id, 
    full_name, 
    website, 
    X(user_location) AS "latitude", 
    Y(user_location) AS "longitude", 
    (
    GLength(
     LineStringFromWKB(
     LineString(
      user_location, 
      GeomFromText('POINT(51.5177 -0.0968)') 
     ) 
    ) 
    ) 
) 
    AS distance 
FROM users 
    ORDER BY distance ASC; 

，結果是 -

我想在Laravel與查詢生成器使用它，這樣（51.5177-0.0968）本2分可以來自用戶輸入。

我已經是 -

DB::table('users') 
    ->select(
      id, 
      full_name, 
      website, 
      DB::raw('X(user_location) AS "latitude"'), 
      DB::raw('Y(user_location) AS "longitude"'), 
      DB::raw('(
         GLength(
          LineStringFromWKB(
          LineString(
           user_location, 
           GeomFromText('POINT(51.5177 -0.0968)') 
          ) 
         ) 
         ) 
        ) 
         AS distance') 
      ) 
    ->orderBy('distance', 'asc') 
    ->get(); 

做，但它無法正常工作。

任何人都可以請幫忙嗎？

我覺得你很親密。試試這個：

DB::table('users') 
    ->select(
     'id', 
     'full_name', 
     'website', 
     DB::raw('X(user_location) as latitude'), 
     DB::raw('Y(user_location) as longitude'), 
     DB::raw('(
       GLength(
        LineStringFromWKB(
        LineString(
         user_location, 
         GeomFromText(POINT(51.5177 - 0.0968)) 
        ) 
       ) 
       ) 
      ) 
       as distance') 
    ) 
    ->where('status', '<>', 1) 
    ->orderBy('distance', 'asc') 
    ->get();
