Hibernate update Query

In this tutorial you will learn about an update query in Hibernate

This tutorial is based on how to write HQl update query in hibernate. In hibernate update query updates the data of the database table when (if any) modification is made to the records. A simple query for update may be written as :

update ClassName set propertiesName = 'valueOfPropertiesToChange' where propertiesName = 'valueOfProperties'

You may set the value using setParameter() method of Query.

Example :

An example is being given below is concerned to update the value of a column of a table after the data modification at run time. To do so at first I have created a table in MySQL named salesorder that contains the fields 'id', 'price', and 'purchaser' with some records in their respective fields. Then created a class that contains some data members, setter getting methods and constructors, this class is a POJO class which object will be persisted into the table salesorder. Now created a mapping file named salesorder.hbm.xml to map the class object with table and a configuration file named hibernate.cfg.xml using which Hibernate will create a connection pool and the required environment setup to work with the database. Finally created a class where we will obtain the configuration, create a SessionFactory and obtain a session using SessionFactory, create a Transaction within which we will try to change the existing data and updates using the update query and executeUpdate() method of Query. The value for changing will be given by user at run time.

Table salesorder

CREATE TABLE `salesorder` ( 
`id` int(15) NOT NULL auto_increment, 
`price` int(25) NOT NULL, 
`purchaser` varchar(25) default NULL, 


package roseindia;

public class SalesOrder {
private int id;
private int price;
private String purchaser;

public SalesOrder()

public SalesOrder(int price, String purchaser)
this.price = price;
this.purchaser = purchaser;

public int getId() {
return id;
public void setId(int id) {
this.id = id;
public int getPrice() {
return price;
public void setPrice(int price) {
this.price = price;
public String getPurchaser() {
return purchaser;
public void setPurchaser(String purchaser) {
this.purchaser = purchaser;

System.out.println("Enter purchaser name to change");
String purchaser = scan.next();
Query query = session.createQuery("update SalesOrder so set so.purchaser='"+ purchaser+"' where so.id= '"+id+"'");
int update = query.executeUpdate();
if(update == 0 || update == 1)
System.out.println(update + " row affected");
System.out.println(update + " rows affected");

System.out.println("Successfully updated");
catch(Exception e)

Output :

1. salesorder table before making the modification

2. When you will execute the java file HibernateUpdateQuery.java (RightClick -> runAs -> Java Application) you will get the output as :

3. salesorder table after modification & updation
