i want to update a first record status into '2' based on button click.
Here is my code :

```
     public function repay(Request $request,$loanid){

    $obj = DB::table('schdls')
    ->where('schdls.loanid','=',$loanid)
    ->where('schdls.status','=',1)->first();

        $obj->status='2';
        $obj->save();

    return redirect('/home')->with('message','updated');
      }

```

But it says Call to undefined method stdClass::save() error,

What am i missing?
