title: Rollback the changes for Update Query
body: <pre><code>UPDATE UPI_ATTRIBUTE SET SITE_INC ='0' 
  WHERE USER_PROFILING_NAME IN ('CAR_IMPLICIT','CAR_EXPLICIT')
  </code></pre>
  
  <p>Above is my query that I am using to update the columns in UPI_ATTRIBUTE table. And suppose if I need to rollback the above changes that I am doing with update query, then how can I use the delete query in the above case? Currently SITE_INC is empty. So after updating the table it will have 0 in that. And If I need to rollback the changes then I need to make it empty again.</p>
  
  <p>How can I delete the value 0 from above column after updating.</p>
