How to edit one column in a row of the database in laravel

I can't update one column of row has multiple columns by laravel

My edit :

public function edit($id)
{
    $addremark=bookappoitment::findOrFail($id);
    return view('admin.ManageTime.addremarks', compact('addremark'));
}

My update:

public function update(Request $request, $id)
{
    $request->validate([
      'Remarks'=>'required'
    ]); 

    $data=bookappoitment::find($id);
    $data->Remarks = $request->get('Remarks');
    $data->save();

    return view('/home');
}

link to update:

<a href="{{route('BookAppoint.update',$addremark->id)}}">Update</a>

form:

<div class="panel-body">
  <div class="row">
    <div class="col-lg-6">
      <div class="form-group">
        <label>Remarks :</label>
        <textarea class="form-control" rows="10" name="Remarks" placeholder="Remarks">{{ $addremark->Remarks }}</textarea>
      </div>

      <a class="btn btn-success btn-mini deleteRecord " href="{{route('BookAppoint.update',$addremark->id)}}">Update</a>

    </div>
  </div>
</div>

You can update 1 (or more, just add to the array) column through the DB class.

DB::table('yourTable')->where('id', $id)->update(['remarks' => $request->input('Remarks')]);

You can also do it for a model like so:

bookappoitment::where('id', $id)->update(['remarks' => $request->input('Remarks')]);

It's in the Laravel documentation here.

<form class="" action="index.html" method="{{ route('BookAppoint.update', $addremark->id) }}">
  @method('PATCH')
  @csrf

  <div class="panel-body">
    <div class="row">

      <div class="col-lg-6">
        <div class="form-group">
          <label for="Remarks">Remarks :</label>
          <textarea name="remarks" rows="10" placeholder="Remarks">{{$addremarks->Remarks}}</textarea>
        </div>
      </div>

      <input type="submit" name="submit" value="Update">

    </div>
  </div>

</form>
