title: Oracle APEX Interactive Report conditional column link display
body: <p>I have an interactive report displaying all the records from articles table. For a logged in author, I would like to display all the records, but the EDIT should be displayed only for those articles written by that author. In articles table, I have the column <code>CREATED_BY</code> which has the author username. </p>
  
  <p>I added a condition to Link Column as Value of Item / Column in Expression 1 = Expression 2 as Expression1=<code>#CREATED_BY#</code> &amp; Expression2= <code>:APP_USER</code></p>
  
  <p>But this does not work. This is the first time I am taking this approach to display edit link based on a condition.</p>
  
  <p>When I added the condition <code>Value of Item / Column in Expression 1 is not null</code> and set Expression1 = <code>#CREATED_BY#</code>, it was still not displaying edit link. So, I think that <code>#CREATED_BY#</code> is returning null. But the record in table has a value &amp; I also see it in report column. </p>
  
  <p>Can someone help? I don't know where I am going wrong. </p>
