I need to update and insert data in table using Java Persistence Query Language. Here is my DAO class code:
public class ApprovalDao {
@Autowired
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void addEntity(EntityValues entity) {
getSessionFactory().getCurrentSession().save(entity);
}
public void deleteEntityValue(EntityValues entity) {
getSessionFactory().getCurrentSession().delete(entity);
}
At first, if you use @Autowired
annotation setter/getteer
methods are redundant. In your case you should youse something like this:
session = sessionFactory.openSession();
session.beginTransaction();
session.update(user);
session.getTransaction().commit();
And surround it with try/catch
construction.
for updating data of fields in table :
public void updateField(){
Query q=getSessionFactory().getCurrentSession().createQuery(
" update SapOrderHDR set
SAP_ORDER_STATUS = 'A' where BC_ORDER_NO='" + bcOrderNo + "'");
q.executeUpdate();
}
This query will update table where BC_ORDER_NO=var
and set BC_ORDER_NO ='A'
. SapOrderHDR
is table entity class
