title: Why do I have ORA-00904 even when the column is present?
body: <p>I see an error   while executing hibernate sql query.</p>
  
  <blockquote>
    <p>java.sql.SQLException: ORA-00904: "table_name"."column_name": invalid identifier</p>
  </blockquote>
  
  <p>When I open up the table in sqldeveloper, the column is present. </p>
  
  <p>The error is only happening in PROD, not in DEV. </p>
  
  <p>What should I check?</p>
