title: Get records closest to hour 05:00 am. I have a hour and minute column and need to get records which are closest to 5am. Hard coding to 5am is also ok
body: <p>SAMPLE DATA:</p>
  <pre><code>order_id  location   departhour  departmin
  121        boston     10          11
  121        boston     14          00
  </code></pre>
  <p>from the above data i want to get the record which has departhour 10 as that is closest to 5am. hour and minute are number datatypes.</p>
