function formatSeconds(seconds)
{
    var date = new Date(1970,0,1);
    date.setSeconds(seconds);
    return date.toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");
}

不建议这样使用， 如果有很复杂的SQL也可以用Laravel的query封装起来，比如像下面的这样。

        $users = \DB::table('users')->select(\DB::raw('users.id,if(cargo_owners.status is  null, vehicle_owners.status, cargo_owners.status) as status, if(cargo_owners.name is  null, vehicle_owners.name, cargo_owners.name) as name,users.`created_at`,cargo_owners.type sub_type, users.type'))
            ->leftJoin('cargo_owners', 'cargo_owners.id'  , 'users.id')
            ->leftJoin('vehicle_owners', 'vehicle_owners.id' , 'users.id');
 $users->paginate();
