title: mySQL UPDATE query returns "0 rows affected"
body: <p>I have this query:</p>
  
  <pre><code>UPDATE phonecalls 
     SET Called = "Yes" 
   WHERE PhoneNumber = "999 29-4655"
  </code></pre>
  
  <p>My table is <code>phonecalls</code>, I have a column named <code>PhoneNumber</code>.  All I want to update is a column named <code>Called</code> to "yes".</p>
  
  <p>Any idea what I am doing wrong?  when I return my query it says 0 rows affected.</p>
