how to update the table in java using hibernate without using hql and sql

If you are using hibernate, you should try to access entities not tables.
The biggest advantage of hibernate is that it provides you ORM (object relational mapping).
Here is the example how to update an entity with hibernate
(of course corresponding table is also updated).

/* Method to UPDATE salary for an employee */
   public void updateEmployee(Integer EmployeeID, int salary ){
      Session session = factory.openSession();
      Transaction tx = null;
      try{
         tx = session.beginTransaction();
         Employee employee = 
                    (Employee)session.get(Employee.class, EmployeeID); 
         employee.setSalary( salary );
         session.update(employee); 
         tx.commit();
      }catch (HibernateException e) {
         if (tx!=null) tx.rollback();
         e.printStackTrace(); 
      }finally {
         session.close(); 
      }
   }

You are creating a Native(SQL) query using createQuery() method instead of createSQLQuery() method so just change your code as follows

session.getTransaction().begin();
Query query = session.createSQLQuery(
    "update DocDetail set DocName = :docname" + " where Id = :docId");
query.setParameter("docname", "Jack");
query.setParameter("docId", 3);
int result = query.executeUpdate();
session.getTransaction().commit();

• Difference between createQuery and createSQLQuery

  hope this will solve your problem

To update object without SQL or HQL you can use next code snippet.

 Session sess = factory.openSession();
 Transaction tx;
 try {
     tx = sess.beginTransaction();
     sess.update(yourObject);
     tx.commit();
 }
 catch (Exception e) {
     if (tx!=null) tx.rollback();
     throw e;
 }
 finally {
     sess.close();
 }

Read documentation about update - possible you have to use merge or saveOrUpdate.

Here a way of updating data into table using hibernate hql:

Configuration cfg = new Configuration();
cfg.configure("HibernateService/hibernate.cfg.xml");

SessionFactory factory = cfg.buildSessionFactory();
Session session = factory.openSession();
Transaction t = session.beginTransaction();

String hql = "UPDATE Userreg SET uname = :uname, uemail = :uemail, uphone = :uphone WHERE uemail = :uemail";

Query query = session.createQuery(hql);
query.setParameter("uname", uname);
query.setParameter("uemail", uemail);
query.setParameter("uphone", uphone);
int rr = query.executeUpdate();

t.commit();

if (rr != 0) {
    return true;
} else {
    return true;
}

you can use hibernate session's merge. such as

User user = session.find("1"); 
//get Persistence entity``String userName = user.getUserName(); //  userName = "enzo"
//user.setUserName("leo");
session.merge(user);
// Test entity user's useName
String userNameNew = session.find("1").getUserName; // now userName is "leo"

I hope can help you;
