ユーザーモデルへのLaravel生のクエリ

Question

私はLaravel Eloquentモデルを作成したい生のSQLクエリを持っています。

問合せ：

SELECT * FROM user 
LEFT JOIN (SELECT user_id, MAX(log_login_id) AS maxid 
FROM log_login 
GROUP BY user_id) 
AS T1 ON user.user_id = T1.user_id 
LEFT JOIN log_login AS T2 ON T2.log_login_id = T1.maxid 
WHERE user.map_id = 101; 

イム..このような何かをしようとしますが、私はかなりの仕事をdoesntの

$users = User::where('user.map_id', session('mapID')) 
     ->leftJoin('(SELECT user_id, MAX(log_login_id) AS maxid 
        FROM log_login 
        GROUP BY user_id) 
        AS T1 ON user.user_id = T1.user_id') 
     ->leftJoin('log_login AS T2 ON T2.log_login_id = T1.maxid') 
     ->orderBy('username', 'asc')->get(); 

どのように私のセットアップ私のクエリに、私は、オブジェクトモデルのリストからを取得するように、雄弁ですか？これは構文上の問題です。

Answer 1

この

$users = User::where('user.map_id', session('mapID')) 
    ->leftJoin(\DB::raw('(SELECT user_id, MAX(log_login_id) AS maxid 
       FROM log_login 
       GROUP BY user_id) 
       AS T1 ON user.user_id = T1.user_id')) 
    ->leftJoin('log_login AS T2 ON T2.log_login_id = T1.maxid') 
    ->orderBy('username', 'asc')->get(); 

または本（テストが、推測ではないとしてみてくださいそれは動作するはずです）

$users = User::where('user.map_id', session('mapID')) 
    ->leftJoin(function($query){ 
     $query->select("user_id", "MAX(log_login_id) as maxid") 
      ->from('log_login as T1') 
      ->groupBy('user_id') 
      ->on('user.user_id','=','T1.user_id') 
    }) 
    ->leftJoin('log_login AS T2 ON T2.log_login_id = T1.maxid') 
    ->orderBy('username', 'asc')->get(); 

あなたはlog_login` `用に設定雄弁モデルを持っています、それは
