title: How to Create a ORACLE Table to store Appointment Time
body: <p>I am trying to add to my current appointment table on ORACLE to store time of the appointment</p>
  
  <pre><code>     ALTER TABLE APPOINTMENT
  add (Timeofappointment to_date NOT NULL)
  </code></pre>
  
  <p>Here the code seems to be fine but the function to_date, or the way I am writing it don't seem to be working.</p>
  
  <p>Any suggestion as I have not found one to be able to work online.</p>
  
  <p>I want it to store time like this: <code>13:00</code></p>
