title: Is there a mechanism to disable insert into table?
body: <p>I have a table that is exists purely to serve as an array for some logic.</p>
  
  <p>The table should have only one row otherwise my logic fails.
  Is there any DDL command to disable insert into table?</p>
  
  <p>As of now - I have inserted that 'one row' of data that is required for my logic, and now, plan to create an after insert trigger to delete the newly entered record. B)</p>
  
  <p>However I noticed that there were some ALTER TABLE commands to disable/ enable keys, so I was wondering if there is an alternative to the trigger code.</p>
