Laravel Eloquent中生成的SQL

I have a users table and a positions table and they have relationship in my Model.

User model

class User extends Eloquent {
    public function position()
    { 
        return $this->belongsTo('Position');
    }
}

Position model

class Position extends Eloquent {
    public function users()
    {
        return $this->hasMany('User');
    }
}

I try to do this.

$users = User::find(1);
echo $users->lastname . "<br>"; // output the lastname
echo $users->position->name . "<br>"; // output the position name
echo $users->toSql(); // output "Select * from user"

My question is how can I get the generated raw SQL? something like

select s.* from users s left join positions p on p.id = s.position_id where s.id = 1 

Im using Eloquent standalone. Thank you in advance.

    Use DB::enableQueryLog();, then try DB::getQueryLog(); and you'll get an array which you can use. Let me know if that works!

    use Illuminate\Support\Facades\DB;
    
    DB::enableQueryLog();
    
    $users = User::find(1);
    echo $users->lastname . "<br>"; // output the lastname
    echo $users->position->name . "<br>"; // output the position name
    
    foreach(DB::getQueryLog() as $item){
        echo $item["query"] .  "<br>";
    }
