Failed to create table using Hibernate and MYSQL
I am new to hibernate and I need to get some strange behavior, below is the scenario.
My java files:
UserDetails.java: -
package org.mahesh.test;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class UserDetails {
@Id
private int userId;
private String userName;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
}
HibernateTest.java is,
package org.mahesh.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.mahesh.securifi.UserDetails;
public class HibernateTest {
public static void main(String[] args) {
// TODO Auto-generated method stub
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Mahesh");
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
}
}
hibernate.cfg.xml is,
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

Try to change the dialect in hibernate.cfg.cml
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
This should fix the problem.
If you want to use MyISAM
package com.mahesh.dialect;
import org.hibernate.dialect.MySQLMyISAMDialect
class MySQL5MyISAMDialect extends MySQLMyISAMDialect {
String getTableTypeString() {
" ENGINE=MyISAM"
}
}
and set the dialect to
<!-- SQL dialect -->
<property name="dialect">com.mahesh.dialect.MySQL5MyISAMDialect</property>

This exception is because there are no UserDetails tables in the database if you want hibernate to create the table add below property to your hibernate.cfg.xml file
<property name="hbm2ddl.auto">create</property>
you can choose the value hbm2ddl.auto validate | update | create | creation-fall depends on your requirement.

I also had CommandAcceptanceException and SQLGrammarException when I upgraded my DB from MySQL 5.1 to 5.7. I changed the dialect in hibernate.cfg.xml
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
This was previously "org.hibernate.dialect.MySQLDialect". This fixed the problem.
