title: PHP/SQL Show rows that are 60 days plus in the past
body: <p>I have a table with a <code>datetime</code> column <code>(Y-m-d H:i:s)</code></p>
  
  <p>I want to be able to show all rows that have a datetime column that is 60 days plus in the past</p>
  
  <p>i have tried this but it doesn't seem to be showing the correct rows:</p>
  
  <pre><code>SELECT * from customer_communication WHERE datetime &lt; DATE_SUB(DATE(now()), INTERVAL 60 DAY) order by datetime DESC
  </code></pre>
  
  <p>There is a <code>customer</code> column in this table too because each customer will have multiple rows. each time they are contacted it adds a new row for that customer so will i need to group by <code>customer</code> or group by <code>datetime</code>?</p>
