JPA setParameter (Numbered Parameter)


In the previous section we studied about the setParameter. Here, we will see setParameter to set a numbered parameter.

We are going to develop an example code to use the numbered parameter in setParameter() method. 

setParameter(int numberedParamter, Object val): This method binds the argument to a positional  parameter. It takes two parameter. Positional parameter number and its value. It also returns an instance of jpa query.

Steps to develop the code:

  1. Database Table: student
  2. Model Class: Student.java
  3. Main Class: JPASetParameterNumberedParameter.java

Database Table: student

CREATE TABLE `student` ( 
`id` int(11) NOT NULL auto_increment, 
`sname` varchar(100) NOT NULL, 
`sroll` int(11) NOT NULL, 
`scourse` varchar(10) NOT NULL, 

Model Class: Student.java

public class Student {

private int id;

public void setId(int id) {

@Column(name="sname", length=100,nullable=false)
private String sname;

* @return the sname
public String getSname() {
return sname;

* @param sname the sname to set
public void setSname(String sname) {
this.sname = sname;

private int sroll;

* @return the sroll
public int getSroll() {
return sroll;

* @param sroll the sroll to set
public void setSroll(int sroll) {
this.sroll = sroll;

private String scourse;

* @return the scourse
public String getScourse() {
return scourse;

* @param scourse the scourse to set
public void setScourse(String scourse) {
this.scourse = scourse;

Student st=(Student)stuIterator.next();
System.out.print(" sroll:"+st.getSroll());
System.out.print(" scourse:"+st.getScourse());
