Hibernate and HSQL

File: Main.java

import org.hibernate.Session;
public class Main {
  public static void main(String[] args) throws Exception {
    HibernateUtil hibernateUtil = new HibernateUtil();
    hibernateUtil.executeSQLCommand("create table survey (id int,name varchar);");
    Session session = hibernateUtil.getSession();
    Survey survey = new Survey();
    survey.setName("Survey");
    System.out.println(survey.getId());
    
    session.save(survey);
    session.flush();
    
    System.out.println(survey.getId());
    Survey surveyInSession = (Survey) session.get(Survey.class, survey.getId());
    System.out.println(surveyInSession.getName());
    session.close();
    hibernateUtil.checkData("select * from survey");
  }
}

Setup Hibernate Environment

File: Main.java

import org.hibernate.Session;
public class Main {
  public static void main(String[] args) throws Exception {
    HibernateUtil hibernateUtil = new HibernateUtil();
    hibernateUtil.executeSQLCommand("create table survey (id int,name varchar);");
    Session session = hibernateUtil.getSession();
    Survey survey = new Survey();
    survey.setName("Survey");
    System.out.println(survey.getId());
    
    session.save(survey);
    session.flush();
    
    System.out.println(survey.getId());
    Survey surveyInSession = (Survey) session.get(Survey.class, survey.getId());
    System.out.println(surveyInSession.getName());
    session.close();
    hibernateUtil.checkData("select * from survey");
  }
}
