You have an error in your SQL syntax - hibernate and mysql - java

I'm learning Hibernate, and during simple demo application, I encounter problem, I can't overcame. There are only two tables, two entity classes and main app. Project is in maven.

I've double check syntax, but can't figure out wha is causing this:
ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'usage) values (900, 10, 'Weyerman', 'Carafa (R) typ I', 'Stout, Porter, Schwarzb' at line 1
Best regards

In your sql table malt you have a column named usage and that name is a reserved word in MySQL so that is why your insert query doesn't work.
The easiest way forward is to change the name to something else, for instance malt_usage
So this will not work:
INSERT INTO malt(filling, ebc, malt_manufacturer, malt_name, usage)
VALUES (900, 10, 'Weyerman', 'Carafa (R) typ I', 'Stout, Porter, Schwarzb')
but this will
INSERT INTO malt(filling, ebc, malt_manufacturer, malt_name, malt_usage)
VALUES (900, 10, 'Weyerman', 'Carafa (R) typ I', 'Stout, Porter, Schwarzb')
In java this is not a problem so there you can keep the name usage if you want
#Column(name="malt_usage")
private String usage;

The literal usage is a keyword in mysql.
https://dev.mysql.com/doc/refman/8.0/en/keywords.html#keywords-8-0-detailed-U
Simplest solution is to simply change the column name to another (non-keyword) term.
Otherwise, try setting
hibernate.auto_quote_keyword=true

First of all, to avoid deprecation warnings, you should use the type safe variant of createQuery:
TypedQuery<Polica> result = openCurrentSession().createQuery("FROM Polica", Polica.class);
It's hard to say why your code is not working, but I have a few ideas what you could try. Note that you don't reference the hibernate.hbm.xml file anywhere and you commented out the reference to some other file Polica.hbm.xml, though the contents are unnecessary anyway as the annotations on the entity class are enough.
You are correctly listing the class through <mapping class="digiwallboard.Entity.Polica"/>, so it should be picked up by Hibernate. My guess is, that either some of your hbm.xml files that you might reference in your real app are interfering somehow, i.e. registering the entity type under a different name, or that your configuration is not picked up for some reason.
You can check which entities Hibernate found by inspecting getSessionFactory().getMetamodel().getEntities(), and if you find your entity there, check what EntityType#getName() reports, as that is the under which you can use the entity in HQL.

Table departments structure:
Name | Null? | Type |
:---------------|:--------:| ------------ :|
DEPARTMENT_ID | NOT NULL | NUMBER(4) |
DEPARTMENT_NAME | NOT NULL |VARCHAR2(30) |
MANAGER_ID | |NUMBER(6) |
LOCATION_ID | | NUMBER(4) |
I have no idea what is happening here...anyhelp is most welcomed...

The problem is that you didn't map the association correctly. Given the name of the table and constraint, I think there's not a manager matching the id you have specified.
A relationship between Department and Manager (assuming a department has only one manager) should look something like:
#Entity
public class Department {
....
#ManyToOne // Assuming a manager can manage multiple departments
Manager manager;
}
#Entity
public class Manager {
// ... id, fields, getters/setters
}
I've used annotations because I find it easier (and probably more common) but you can do the same with XML.
I would suggest to check the Hibernate ORM documentation to figure out how to map associations.

"QuerySyntaxException: User is not mapped" when adding an entity from another package

I've made a Hibernate configuration maven project (built with the maven-shade-plugin) to allow my codebase to use one unified "database class". However, the class does not seem to map (throws a org.hibernate.hql.internal.ast.QuerySyntaxException: User is not mapped exception at runtime) when called from outside the running project.
When ran within the project, everything works fine. However, Hibernate fails to map the entity when run from outside the project.

#Entity
#Table(name = "users")
public class User extends BaseEntity {
Your entity is called User but its mapped to a table called users.
Either change the entity to Users or table to user.
That should do it.

Try:
Configuration configuration = new Configuration().configure();
for (Class cls : getEntityClassesFromPackage("com.example.hib.entities")) {
configuration.addAnnotatedClass(cls);
}

Whelp, I found out what was going on. My galaxy brain decided to do addAnnotatedClass(anoClass.getClass()) on a Class object, so I was trying to declare java.lang.Class as a Hibernate Entity... Oh well, I'm just an idiot. Changed it to just addAnnotatedClass(anoClass) and it works just fine.

hibernate 5.2.2: ManyToOne first example

the system that I'm implementing is composed of:
Eclipse Neon 4.6 + maven (integreted) + Hibernate 5.2.2 + Mysql (i use MySql Workbench 6.3)
algorithm:
I tried to create this java application on eclipse:
a student entity and an address entity (the some address can be used for many students)
info:
I created only a htmanytoone schemas on mysql, and I want hibernate it to take care of creation and management of the entities on.
I hope there are no problems of continuity (I modified the code several times )

Here is the implementation of the CustomerService class:

public List<Customer> getAllCustomers() {

Here is the implementation of the CustomerDao:
package com.kylewalker.wellness.dataaccess;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.stereotype.Repository;

template.delete(foundCustomer);
}
public List<Customer> getAllCustomers() {
return (List<Customer>)template.find("from Customer");
}
}
Here is the Client.java main class I'm running to test it all. (I was trying to do a JUnit test originally but kept having problems, so I figured I'd try testing it this way):
package com.kylewalker.wellness.client;
import java.util.List;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.kylewalker.wellness.domain.Customer;
import com.kylewalker.wellness.services.CustomerService;
public class Client {
public static void main(String[] args) {
ClassPathXmlApplicationContext container = new ClassPathXmlApplicationContext("hibernate-application.xml");
try {
CustomerService customer = container.getBean(CustomerService.class);
Customer c1 = new Customer("Joe", "Smith", "jsmith#gmail.com");
System.out.println(c1);
System.out.println("The customer last name is " + c1.getLastName());
customer.newCustomer(c1);
List<Customer> allCustomers = customer.getAllCustomers();
for (Customer c : allCustomers) {
System.out.println(c);
}
} finally {
container.close();
}
}
}
And finally here is the error trace I'm getting when I run the Client class :

I'd try with a newer version of hsqldb. The version you have is quite outdated. As the error is raised from the database (function not supported), but the insert statement causing the issue looks fine, I think an update to the new version will do the trick.

You should use EntityManager instead of HibernateTemplate wich is deprecated from Spring 2.5
#Repository
public class GenericService<T> implements IGenericService<T> {
protected EntityManager em;
public EntityManager getEm() {
return em;
}
#PersistenceContext
public void setEm(EntityManager em) {
this.em = em;
}
#Transactional
#Override
public T create(final T t) throws DefaultException{
return this.em.persist(t);
}
...
}

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

You have an error in your SQL syntax - hibernate and mysql - java

The literal usage is a keyword in mysql. https://dev.mysql.com/doc/refman/8.0/en/keywords.html#keywords-8-0-detailed-U Simplest solution is to simply change the column name to another (non-keyword) term. Otherwise, try setting hibernate.auto_quote_keyword=true
