title: using group_concat in PHPMYADMIN will show the result as [BLOB - 3B]
body: <p>I have a query which uses the GROUP_CONCAT of mysql on an integer field.<br>
  I am using PHPMYADMIN to develop this query. My problem that instead of showing 1,2 which is the result of the concatenated field, I get [BLOB - 3B].  </p>
  
  <p>Query is</p>
  
  <pre><code>SELECT rec_id,GROUP_CONCAT(user_id)
  FROM t1
  GROUP BY rec_id
  </code></pre>
  
  <p>(both fields are unsigned int, both are not unique)</p>
  
  <p>What should I add to see the actual results?</p>
