Hello Friends,
I am developing on sample application using Struts 1.2, Hibernate 3.2 Oracle 9i, Weblogic 8.1
Table is EMP table in oracle.
My application main objective is To display emp data on JSP.
I have successfully done insert data, update data, delete data,retrieving (primary key).
I am not able to retrieve data using non primary key value(like mgr column in emp table).
My code is:
Code:
public List listMgrEmp(int mgr){
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
String qry ="from empBean.Employee as emp where emp.mgr= "+mgr;
List result = session.createSQLQuery(qry).list();
session.getTransaction().commit();
System.out.println("exit from listMgrEmp method");
return result;
}
When I tried to do I am getting below error:
Code:
