Spring hibernate: org.hibernate.exception.SQLGrammarException

Question

My DAO layer code is as follows:

package com.app.dao;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import com.app.pojo.InterviewerPojo;

@Repository("interviewer_details_dao")
public class InterviewerDetailsDaoImpl implements InterviewerDetailsDao {

    @Resource(name="sessionFactory")
    private SessionFactory factory;
    /*private HibernateTemplate template;
    public void setSessionFactory(){
        template = new HibernateTemplate(factory);
    }*/
    /*private HibernateTemplate template = new HibernateTemplate(sessionFactory);*/
    @Override
    public void saveInterviewDetails(InterviewerPojo interviewerPojo) {

/*      Session sess = factory.getCurrentSession();
        try{
            sess.getTransaction().wasCommitted();
        Transaction trans = sess.beginTransaction();
        System.out.println("a");
        sess.saveOrUpdate(interviewerPojo);
        sess.getTransaction().commit();}
        catch(Exception e){
            throw e;
        }*/
        System.out.println("b");
        factory.getCurrentSession().save(interviewerPojo);
    /*  System.out.println(interviewerPojo);
        template.saveOrUpdate(interviewerPojo);
        System.out.println("b");*/

        System.out.println("done");

    }

}

the same code as above was running if i am getting the values from database as follows sessionFactory.getCurrentSession().createQuery("select m from emp m).list; But as I writing another page to insert values then it is having problem *As you can see i used same concept, I populated MODEL(POJO) class by another MODEL(pojo) which i have taken from database by above query* and now debugging goes upto "template.saveOrUpdate" and throws exception as follows

POJO source code:

package com.app.pojo; 
import java.io.Serializable; 
import javax.persistence.*; 

@SuppressWarnings("serial") 
@Entity @Table(name="interviewer") 
public class InterviewerPojo implements Serializable {
    private int eid;

    private int vid; 

    @Id @GeneratedValue(strategy=GenerationType.SEQUENCE) 
    private int i_eid; 

    private String i_name; 

    private String password; 

    public int getEid() { 
        return eid; 
    } 

    public void setEid(int eid) { 
        this.eid = eid; 
    } 
}

Hibernate config:

<property name="hibernateProperties"> 
    <props>
        <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
        <prop key="hibernate.formatsql">true</prop>
        <prop key="hibernate.showsql">true</prop>
        <prop key="hibernate.hbm2ddl.auto">validate</prop>
    </props> 
</property>

Also, easier to turn on SHOW SQL and gather incorrectly generated SQL from the log file. — Taky

@Taky : <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop> <prop key="hibernate.formatsql">true</prop> <prop key="hibernate.showsql">true</prop> <prop key="hibernate.hbm2ddl.auto">validate</prop> </props> </property> but still it doesn't showing sql while table is generated automatically as application runs but i insert in interviewer via SAVE it gives exception :( I'll post InterviewerPojo in next comment — prashast Kr. rajput

@Taky : POJO is as follows: Removed some getter/setters and toString() package com.app.pojo; import java.io.Serializable; import javax.persistence.*; @SuppressWarnings("serial") @Entity @Table(name="interviewer") public class InterviewerPojo implements Serializable{ private int eid; private int vid; @Id @GeneratedValue(strategy=GenerationType.SEQUENCE) private int i_eid; private String i_name; private String password; public int getEid() { return eid; } public void setEid(int eid) { this.eid = eid; } } — prashast Kr. rajput

In your error log, it showed that you're using MySQL. However, you configured Hibernate dialect was HSQLDialect.

org.hibernate.dialect.HSQLDialect

You should remove this dialect property, Hibernate can automatically detect the right dialect through JDBC driver. Or you modify to the correct dialect on your own.
