title: Selecting A Date Between Another Field's Date and Other Date
body: <p>So, here's what I'm trying to accomplish - finding a date between an existing date and 30 days after.  My subquery code:</p>
  
  <pre><code>select sldate
  from sldaterefret
  group by sldate
  having sldate between orig_sldate + 30
  </code></pre>
  
  <p>Hope that makes sense.  As always, thank you in advance.</p>
