Re: Delete records from Database

[Larry Meadors]

We need more than "my deleteEventAction doesen't work" here.

Are you getting SQLException? NullPointer? Stack trace? Referential constraints? Throw us a bone here. :)

Is this iBATIS 1.x? It looks like it - you should be using 2.x for new development.

Hi!

I need some help with deleting some records from the database. I have two tables EVENT with column: eventId and EVENTTIMETABLE with columns: eventTimeTableId and eventId. I want to delete an event with a certain Id and all the timetables corresponding to that event. I will send my code... if you please look at it and tell me what I do wrong because my deleteEventAction doesen't work!

 

 

public void deleteEvent(int eventId) throws DaoException {
    try {
      eventDaoManager.startTransaction();
      eventDao.deleteEvent(eventId);
      eventDaoManager.commitTransaction();
    } catch (DaoException e) {
      try { storeDaoManager.rollbackTransaction(); } catch (Exception e2) 

      throw ((DaoException) e.fillInStackTrace());
    }
  }

 

 

 void deleteEvent(int eventId)
            throws DaoException;

 

 

public void deleteEvent(int eventId)
              throws DaoException {
          Object parameterObject = new Integer(eventId);
          executeUpdate("deleteEvent",  parameterObject);
          }

 

 

 

<mapped-statement name="deleteEvent">
    delete EVENT,EVENTTIMETABLE fromEVENT,EVENTTIMETABLE  where EVENT.EVENTID = #value#  and EVENT.EVENTID = EVENTTIMETABLE.EVENTID
  </mapped-statement>

 

 

public class DeleteEventAction extends BaseAction {

 

   public ActionForward doPerform(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {

 

     OrganizAccountForm orgAcctForm = (OrganizAccountForm) form;
     String orgUsername = orgAcctForm.getOrganizAccount().getOrgUsername();

     int eventId = Integer.parseInt(request.getParameter("eventId"));

    tugis.deleteEvent(eventId);

 

     request.setAttribute("eventList", tugis.getEventsByOrgUsername(orgUsername));

    return mapping.findForward("success");
}
}

 

<action path="/portal/deleteEvent" type="tugis.presentation.action.DeleteEventAction"
                        name="organizAccountForm"  scope="session"
                        validate="true" input="/jsp/ViewRegisteredEvent.jsp">
            <forward name="success" path="/jsp/ListEvents.jsp"/>
    </action>

 

 

And in the JSP code:

 

 <html:link paramId="eventId" paramName="event" paramProperty="eventId" page="/portal/deleteEvent.do">Delete</html:link> 

 

 

Well, please someone take a look and help me out! Or maybe someone have done something similar already and send me an example!

 

Thanks!
