title: Substring only if string length > 2
body: <p>I was wondering if it was possible to only substring if the string length is > 2?</p>
  
  <p>Here is my sample statement: </p>
  
  <p><code>Select SUBSTRING(ABRESC, 1, 2) + '-' + SUBSTRING(ABRESC, 3, 5) AS ABRESC From TABLE</code></p>
  
  <p>However, some fields are only 2 chars long so i was wondering if its possible to only substring when its longer than 2 chars?</p>
