body: <pre><code>ID  | NAME  
  ----|--------  
  1   |Ann  
  2   |Jake  
  1   |Julie  
  3   |Paul  
  2   |Shane  
  4   |Kumi
  </code></pre>
  
  <p>I want to concatenate values using <code>stuff()</code> as below. And the single values should not be affected by the <code>stuff()</code> function.</p>
  
  <pre><code>ID  | NAME  
  ----|--------  
  1   |Ann,Julie  
  2   |Jake,Shane  
  3   |Paul  
  4   |Kumi
  </code></pre>
  
  <p>How to do that?</p>
