title: Laravel / Eloquent whereIn with null
body: <p>How do I apply Laravel's Eloquent whereIn() so that it includes null?</p>
  
  <p>I've tried:</p>
  
  <pre><code>User::whereIn("column", [null, 1, 2]) -&gt; get();
  </code></pre>
  
  <p>And</p>
  
  <pre><code>User::whereIn("column", [DB::raw("null"), 1, 2]) -&gt; get();
  </code></pre>
  
  <p>But both queries return no results.</p>
  
  <p>Thanks!</p>
