Can't fix error in Beginner Hibernate Program [duplicate]

This question already has answers here:
Invalid syntax error "type= MyISAM" in DDL generated by Hibernate
(7 answers)
Closed 2 years ago.
I've just started learning Hibernate, and attempted the example at https://www.javatpoint.com/example-to-create-hibernate-application-in-eclipse-ide , with slight modifications. I received a huge error log -

}
The mysql-connector-java-5.1.48-bin.jar file has been added to the classpath. So have all the other jars specified in the example I'm attempting.
Please let me know what the problem is.

It turned out the solution was there on StackOverflow, albeit under a different heading:
Invalid syntax error "type= MyISAM" in DDL generated by Hibernate
Long story short, change the dialect in hibernate.cfg.xml to org.hibernate.dialect.MySQL5Dialect and things will run fine.

java - hibernate ConstraintViolationException after changing number of parameters

I realized I needed 2 more columns for my table (date and hour, both of which are String type) and I added them in the database, model with constructors, getters and setters, hibernate file and everywhere in the repository, synchronized multiple times, but I get this error telling me 'hour' can't be null and I have no idea what it is talking about.
Anyone have any idea what it could be?
ERROR: Column 'hour' cannot be null

When modifying your schema your new columns will have value of Null for all records, seems like you have constraint of not null, in your java model you can specify that these columns can be null
#Column(nullable=true)

Hibernate is trying to create entity in hibernatedemo schema. You need to create that schema in database. I did not see your configuration that is pointing to hibernatedemo schema. The cfg.xml is generated by MyEclipse Hibernate tools. Check that configuratioon.
How to create schema in PostGreSQL Link
CREATE SCHEMA IF NOT EXISTS schema_name
After creating schema try again to start your application

You can simply add that tag to your config xml file
<property name="hibernate.hbm2ddl.auto">update</property>

Hibernate exception when create table

I just started creating project in Hibernate, and I have problem at the begining.
While I try create a simple table I get these errors:

And i can't find solution. Strange is i get warning about deprecation of org.hibernate.ejb.HibernatePersistence, but i can't use it. I use org.hibernate.jpa.HibernatePersistenceProvider as is shown below.
Anything strange thing is error about no table named "User". Of course is not there, I want to create it!
Additionaly I am using Intellij Idea 14 if its important.
Tere are my class and config file:
persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="2.1">
<persistence-unit name="NewPersistenceUnit">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<properties>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/gmlDatabase"/>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="hibernate.connection.username" value="lukasz"/>
<property name="hibernate.connection.password" value="p4ssw0rd"/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hbm2ddl.auto" value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
User.java:
#Entity
public class User {
#Id
#GeneratedValue
private Long id;
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
and Main.java:
public class Main {
public static void main(String[] args) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("NewPersistenceUnit");
EntityManager entityManager = entityManagerFactory.createEntityManager();
User user = new User();
user.setName("Janek");
entityManager.getTransaction().begin();
entityManager.persist(user);
entityManager.getTransaction().commit();
entityManager.close();
entityManagerFactory.close();
}
}

I don't believe using create-drop will update an in-place schema to re-add the table that you dropped. Try:
<property name="hbm2ddl.auto" value="update"/>
This is create a schema if one doesn't exist, and attempt to modify an existing one to match the mapping you have defined.
Also see this,
Hibernate hbm2ddl.auto possible values and what they do?

First of all check permissions of user (in this case yours is "lukasz"), be sure that you have create database permission. If user doesn't have permission , you can use this command ;
GRANT ALL PRIVILEGES ON * . * TO 'lukasz'#'localhost';

A Couple things stand out to me.
It looks like the exception is coming from an attempt to insert into the user table. From the stack trace it looks like it's being thrown when you call persist. You also say you're trying to create the user table. Unless I've been misusing EM.persist() all these years, it won't create a table, it will just insert/update that record in the table. You need to actually go into your SQL and create the user table. Something like
CREATE TABLE gmlDatabase.User (
id NUMBER,
name VARCHAR(255)
);
Specific syntax may vary depending on what database software you are using
If the table isn't going to have the same name as the hibernate class name you'll need to add a name field to the #Table annotation.
#Table(name="user_table", schema="gmlDatabase")
public class Table {
...
I don't think you'll actually need that in this case, though. It looks like you want the class and table to both have the name "User".
Finally, try listing the specific class under the persistent-unit tag in your persistence.xml Something like
<persistence-unit name="NewPersistenceUnit">
...
<class>com.pkg.otherpkg.User</class>
</persistence-unit>

Add a #Table(schema="gmlDatabase") to the Entity
UPDATE
I guess Hibernate creates an AUTO_INCREMENT for the primary key in the User table? If so you've to set the GenerationType to IDENTITY.
#GeneratedValue(strategy=GenerationType.IDENTITY)

Ok, I partly solved problem.
Partly, because I have to manually create table and correct columns.
This is log, but it isn't so hopefully.
http://pastebin.com/uLhz5nUK
I rolling back every changes in my code, and now it look like in first post.
Now question is why hibernate doesn't create this table?

JPA, HIBERNATE strange error

i dont know why im getting this error, i tryed a lot of different persistence.xml configs over the internet, but the error never change...
and in my classpath i have all the .jars from required folder from this hibernate download ( http://hibernate.org/orm/) and i downloaded the validator, i have everything in WebContent/web-inf/libs and the hibernate.xml is in the src/meta-inf....
what can be?
