Make this query more efficient

Question

I'm terrible at writing queries that are dealing with large datasets. I wanted to take a stab at Laravel and see what I can come up with. Is there a better way to write this query and output the results?

Code

$visitors = DB::table('visitors')
            ->where('id_client',1)
            ->select('id', 'ip', DB::raw('count(*) as total'), 'date', 'city', 'region')
            ->groupBy('ip')
            ->orderBy('date', 'DESC')
            ->simplePaginate(25);

Results

@foreach($visitors as $visitor)
               <tr>
                        <td>
                            {{$visitor->id}}
                        </td>
                        <td>
                            @if (date('F d, Y', strtotime($visitor->date)) === date('F d, Y'))
                                Today
                            @else
                                {{ date('F d, Y', strtotime($visitor->date)) }}
                            @endif  
                        </td> 
                        <td>
                            {{$visitor-total}}
                        </td>                       
                        <td>
                            {{$visitor->city}}
                        </td>
                        <td>
                            {{$visitor->region}}
                        </td>
                 </tr>
          @endforeach

          {!! $visitors->render() !!}

Also, I get the error Use of undefined constant total - assumed 'total' when I try to load the page.

Any help would be greatly appreciated. Thanks!

Answer 1

The query looks good as long as it does what you need.

If your query runs too slow, maybe you can add an index to your 'id_client' column to make the search faster (if you don't have it already of course).
