Hibernate ScrollableResults

In this tutorial we are going to introduce concept of Hibernate ScrollableResults.

Hibernate ScrollableResults :

In Hibernate ScrollableResults is concept to retrieve the database content one by one in place of entire data at once.
It is defined in org.hibernate.ScrollableResults .You can iterate records through ScrollableResults object.

some methods -

  • next() : It is of boolean type. It returns true if another result is available.
  • previous() : Boolean type. Returns true if there is a previous result.
  • last() : Boolean type. Returns true if there are any result.
  • first() : Boolean type. Returns true if any result presents.
  • nextRow() -It returns the next row of your database table.
  • close() - It releases resources immediately.

There are many more methods.

Example : In this example we are showing how to use ScrollableResults in Hibernate applicaion.

package net.roseindia.main;

import net.roseindia.util.HibernateUtil;

import org.hibernate.Query;
import org.hibernate.ScrollableResults;
import org.hibernate.Session;

public class MainClazz {

public static void main(String[] args) {
Session session = HibernateUtil.getSessionFactory().openSession();

String hql = "SELECT stud.roll, stud.name, stud.course FROM Student stud ";
Query query = session.createQuery(hql);
ScrollableResults results = query.scroll();
System.out.println("RollNo.\tName\tCourse");
while (results.next()) {
System.out.print(results.get(0));
System.out.print("\t" + results.get(1));
System.out.print("\t" + results.get(2));
System.out.println();
}
results.close();
session.close(); // session is closed
}
}

Output :

Hibernate: select student0_.roll_no as col_0_0_, student0_.name as col_1_0_, student0_.course as col_2_0_ from student student0_
RollNo.   Name     Course
