title: Compile view with compilation error, noot show errors command says no errors
body: <p>I have added to my view one field.</p>
  
  <p>When I compile it with sqlplus I get warnings:</p>
  
  <blockquote>
    <p>Warning: View created with compilation errors.   </p>
    
    <p>Warning: View created with compilation errors.</p>
  </blockquote>

  <blockquote>
    <p>No errors.</p>
  </blockquote>
