title: How to concatenate result strings in a MS Access Query obtained by GROUP BY
body: <p>I have seen that strings can be concatenated in Access with &amp;.</p>
  
  <p>However, I cannot write the following query:</p>
  
  <pre><code>SELECT age, &amp;names ==&gt; this line does not work, how can I concatenate the strings? 
      FROM table GROUP BY age;
  </code></pre>
  
  <p>So that I get for example: <code>"30; JohnWilliamPeter",</code> all of them 30 years old.</p>
  
  <p>Any way to do that?</p>
