Question

我使用的是Laravel v5.1.4。我在网上搜索但我找不到任何解决方案。我尝试了很多方法，但我无法弄清楚如何将此查询转换为Eloquent或Fluent Query Builder。这是使用select的工作查询。

DB::select("SELECT t1.id,t1.date1,t1.date2, t2.name as pick, t3.name as dest
        FROM reservations AS t1
        LEFT JOIN prices AS t2 ON t1.pick = t2.id
        LEFT JOIN prices AS t3 ON t1.dest = t3.id
        ORDER BY t2.name ASC
        ");

我想使用Eloquent或Fluent功能，例如分页。如果你能帮我解决这个问题，我将不胜感激。

Answer 1

我已经解决了。我希望对有相同问题的人有帮助:)）

DB::table('reservations')->join('prices as t1','reservations.pick',"=","t1.id")
                        ->join('prices as t2','reservations.dest',"=","t2.id")
                        ->select('reservations.id','t1.name as result1','t2.name as result2')->paginate(10);

Answer 2

尝试这样的事情。它是你如何转换的想法

DB::table('users')
            ->LeftJoin('role_user', 'users.id', '=', 'role_user.user_id')
            ->LeftJoin('roles', 'roles.id', '=', 'role_user.role_id')
            ->select('users.*', 'roles.name as role');

我不知道如何将此查询转换为eloquent或Fluent查询构建器
