body: <p>I have a table <strong>Ticket</strong> that has the <strong>id</strong> (autoincremental), <strong>ticket_number</strong> (trigger that reads a sequence), <strong>value</strong> and <strong>date</strong> in Oracle. And I want to do the following:</p>
  
  <pre><code>INSERT INTO TICKET (value, date) values (100, TO_DATE('07-29-2015', 'mm-dd-yyyy')) returning ticket_number into :ticket_number;
