title: Oracle apex classic report hidden column
body: <p>I have a classic report region in my oracle apex application, with query </p>
  
  <pre><code>SELECT SENDER,SUBJECT,SDATE,MAIL_NO
  FROM MAIL
  </code></pre>
  
  <p>I want to hide the column 'MAIL_NO' but also want to access its value in front end, so I can not use <em>hidden column</em> property of classic report. I need one more similiar region in the same page so that I can not use tabular form and it's <em>hidden column save state</em> property of tabular column. How can I achieve this using classic report in oracle apex ?</p>
