Insert using native query

DrRakha

Following example show you how to insert using native query in your JPA model .You set the parameter of record using setParameter function . You set the number of the parameter based on its order using question mark (?) .

Code:

package com.codemiles.jpa;

import java.util.Date;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.Query;

/**
 * @author codemiles.
 *
 */
public abstract class JPAService {
    private EntityManager entityManager;

    /**
     * @param args
     */
    public void insertTopic(){
    EntityManagerFactory factory = Persistence
            .createEntityManagerFactory("persistenceUnitName");
    entityManager = factory.createEntityManager();
    entityManager.getTransaction().begin();
    insertTopic(1,"Ree",new Date());
    entityManager.getTransaction().commit();
    entityManager.close();
    factory.close();

    }
 
    /**
     * @param id
     *   id of the new topic.
     * @param title
     *   title of the new topic.
     * @param creationDate
     *   creation date of the topic.
     */
    public void insertTopic(int id,String title,Date creationDate){
    Query query = entityManager.createNativeQuery("INSERT INTO topic (ID, TITLE,CREATION_DATE) " +
            " VALUES(?,?,?)");
        query.setParameter(1, id);
        query.setParameter(2, title);
        query.setParameter(3, creationDate);
        query.executeUpdate();
    }
   

}

 

The entity class :

Code:

package com.codemiles.jpa;
import java.util.Collection;
import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;



@Entity
@Table(name="TOPIC")
public class Topic implements java.io.Serializable{
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    @Id
    private int Id;
    private String title;
    private Date creationDate;
    private Date modifedDate;
    private String content;
    @OneToMany(mappedBy="topic")
    private Collection<Comment> comments;

    public int getId() {
        return Id;
    }
    public void setId(int id) {
        Id = id;
    }
    
    @Column(name="TITLE")
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
     @Temporal(TemporalType.DATE)
    @Column(name="CREATION_DATE")
    public Date getCreationDate() {
        return creationDate;
    }
    public void setCreationDate(Date creationDate) {
        this.creationDate = creationDate;
    }
     @Temporal(TemporalType.DATE)
    @Column(name="MODIFED_DATE")
    public Date getModifedDate() {
        return modifedDate;
    }
    public void setModifedDate(Date modifedDate) {
        this.modifedDate = modifedDate;
    }
    
    @Column(name="CONTENT")
    public String getContent() {
        return content;
    }
    public void setContent(String content) {
        this.content = content;
    }
    public void setComments(Collection<Comment> comments) {
    this.comments = comments;
    }
    public Collection<Comment> getComments() {
    return comments;
    }
}
