title: MySQL Delete with Group By
body: <p>I am running a query successfully using in MySQL 5.5</p>
  
  <pre><code>SELECT columnA
  FROM
    table
  GROUP BY
    columnA
  HAVING
    count(*) &gt; 1
  </code></pre>
  
  <p>However, I need to run this same query using DELETE and I'm a little unsure how to delete ? i.e. the returned results should be deleted ?</p>
  
  <p>Any ideas ?</p>
