ايريد ان اعرف كيفية اظهار نتيجة استعلام في textfield باستعمال Hebernate

كيفيه اظهار نتيجه الاستعلام

هذا امر ليس له علاقه بالـ Hibernate

فانت تقوم باستعاده نتيجه الاستعلام

وبعدها تضعها فى TextField باستخدام الداله setText

كيفيه الحذف والاضافه والتعديل

يكون ذلك عبر استخدام الـ Session Object

للحذف

session.delete(object);

للتعديل

session.update(object);

للاضافه

session.save(object);

وبعدها تستخدم commit

session.getTransaction().commit();

لتنفيذ العملية

بارك الله فيك اخي

انا مش عارف ايه المكتبه اللى انت مستخدمها فى كدا

import islam.prayer.times.util.HibernateUtil;
import islam.prayer.times.entity.Time;

ملهاش لازمه دى

session.getTransaction().commit();

هو الـ Query دا

Query q = session.createQuery(hql);
List resultList = q.list();

انت كدا عامله انه يعمل اختيار لجميع صفوف الجدول Time

وبعدين الداله

  private void displayResult(List resultList) {
    	Time time = new Time();
    	t1.setText(time.getDatep().toString());
    	t2.setText(time.getPf().toString());
    	t3.setText(time.getPd().toString());
    	t4.setText(time.getPa().toString());
    	t5.setText(time.getPm().toString());
    	t6.setText(time.getPi().toString());

	}

انت كدا مش استخدمت الـ list اللى حصلت عليها من الـ Query

وعملت كائن جديد وبدأت تاخد منه البيانات
