title: Check if a value is not in a list in Application Insights Query Language?
body: <p>Is there a shorter way to check if a property, say <code>user_id</code> is not within a given list:</p>
  
  <pre><code>customEvents 
  | where user_Id != 123
      and user_Id != 234
      and user_Id != 345
  </code></pre>
