import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import com.bethecoder.tutorials.hibernate.basic.Company;
import com.bethecoder.tutorials.hibernate.basic.util.HibernateUtil;
public class HQLNamedParamListTest {
/**
* @param args
*/
public static void main(String[] args) {
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
String HQL_QUERY = "from Company comp where comp.id in ( :company_id ) ";
Query query = session.createQuery(HQL_QUERY);
query.setParameterList("company_id", new Integer [] { 2, 4, 6} );
List<Company> companies = query.list();
System.out.println("Selected row count : " + companies.size());
for (Company company : companies) {
System.out.println(company);
}
session.getTransaction().commit();
session.close();
}
}

It gives the following output,
Selected row count : 3
{ id = 2, name = ABC, employeeCount = 23430,
projectCount = 160, address1 = add11, address2 = add22 }
{ id = 4, name = IJK, employeeCount = 67890,
projectCount = 850, address1 = add1112, address2 = add2223 }
{ id = 6, name = RNK, employeeCount = 98890,
projectCount = 8478, address1 = add1412, address2 = add27823 }
