title: SQL Formatting a field
body: <p>In my DB, I have a column called <code>telephone number</code>.<br>
  Most of the numbers are ###-###-#### some of them are ###########.  How can I run a query to format all numbers to look the same?</p>
  
  <p>I'd prefer:</p>
  
  <pre><code>###-###-#####
  </code></pre>
