package com.bethecoder.tutorials.hibernate.basic.tests;
import java.util.List;
import org.hibernate.Session;
import com.bethecoder.tutorials.hibernate.basic.Company;
import com.bethecoder.tutorials.hibernate.basic.util.HibernateUtil;
public class HQLWhereClauseTest {
/**
* @param args
*/
public static void main(String[] args) {
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
//String HQL_QUERY = "from Company comp where comp.id = 1";
//String HQL_QUERY = "from Company comp where comp.name='ABC'";
String HQL_QUERY = "from Company comp where comp.employeeCount >= 23430";
List<Company> companies = (List<Company>) session.createQuery(HQL_QUERY).list();
for (Company company : companies) {
System.out.println(company);
}
session.getTransaction().commit();
session.close();
}
}

It gives the following output,
{ id = 2, name = ABC, employeeCount = 23430,
projectCount = 160, address1 = add11, address2 = add22 }
{ id = 3, name = MNO, employeeCount = 26790,
projectCount = 670, address1 = add111, address2 = add222 }
{ id = 4, name = IJK, employeeCount = 67890,
projectCount = 850, address1 = add1112, address2 = add2223 }
{ id = 5, name = ART, employeeCount = 67890,
projectCount = 850, address1 = add1112, address2 = add2223 }
{ id = 6, name = RNK, employeeCount = 98890,
projectCount = 8478, address1 = add1412, address2 = add27823 }
{ id = 7, name = AOQ, employeeCount = 97890,
projectCount = 4578, address1 = add17892, address2 = add2893 }
