I shall b thankful to u :)
The error is caused by a space character in the table name Central Appointment. If you really want to use a table name with a space in it, you should quote it using backticks:
#Table(name = "`Central Appointment`")
But remember: you will also have to use similar quoting tricks when executing SQL queries directly in the database (in case of Postgres it's double quotes - select * from "Central Appointment" where ...). So it might be more convenient and also more colleague-friendly to not use such exotic table names and instead replace the space character with an underscore:
#Table(name = "Central_Appointment")
Just try following steps:-
In the hibernate.cfg.xml, add this property
hibernate.default_catalog = MyDatabaseName
In the hibernate.reveng.xml, add all the table filters like this
table-filter match-name="MyTableName" (just this, no catalog name here)
Regenerate hibernate code
Remove space if you have added while mentioning the column name
#Column(name="PassengerName")

I am new to SQL and Hibernate and I need help with the following:
Entity Product has (OneToMany) Entity Category which has some options (List).
I want when saving a Product this to be saved if not already existing, otherwise to be updated. Also, when saving a product I need to save the Category if the Category does not exist. When deleting/updating a Product the Category should not be deleted/updated.
When I tried to have a #GeneratedValue for Category id, each time I run the app, the Products were updated, but the Categories were re-inserted(with different id, without deleting the previous ones).
I then tried the below code (having the Category name as #Id since I know that the name is unique) but then I get the errors you see.
What do I do wrong? I have searched Google and stackoverflow but I could not find a suitable/plain enough solution.
hibernate.cfg.xml:

I had this exception on exactly the same data-base vendor.
The culprit was this line:
#Column(nullable = false, unique = true)
private int fieldName = -1;
So that, it enforced the DB attribute to be unique, when the incoming data
did not satisfy this constraint.
In this case, it has to be set to:
unique = false
I have created a project with SQL Server which the files:
UserDAO.java*
public class UserDAO
{
private static SessionFactory sessionFactory;
static
{
sessionFactory = HibernateUtility.getSessionFactory();
}
#SuppressWarnings("unchecked")
public static List<User> findAll()
{

Criteria crit = session.createCriteria(User.class);
List<User> userList = crit.list();
return userList;
}

Any help is appreciated. Thanks in advance.
USER is a Reserve Word and needs to be escaped in query using square bracket [] while querying.
If you are using annotations, escape through single quotes. '', like below
#Table(name="`user`")
Also refer here for similar issue.
Faced pretty similar issue, when Column name value has space in between.
Note : Hibernate 5.3.7 with SQLServer 2014
#Entity
#Table(name = "TableName")
public class Customer {
#Id
#Column(name = "cid")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int customerId;
#Column(name = "Customer Name")
private String customerName;
---
---
ERROR:
Solution 1 : Template Literals
Solution 2:
-We could remove the space or add '_' in between
#Column(name = "CustomerName") or #Column(name = "Customer_Name")
Note: Name is also a reserved word in SQLServer.

Hibernate: insert into EMPLOYEE (first_name, last_name, salary) values (?, ?, ?) select scope_identity()
Please help to resolve the exceptions.
Thanks in advance!
The MS Access dialect does not exists in the Hibernate library. This causes that Hibernate is not capable to detect the identity column and act as required for MS Access.
org.hibernate.exception.SQLGrammarException: could not insert: [Employee] Hibernate: insert into EMPLOYEE (first_name, last_name, salary) values (?, ?, ?) select scope_identity()
select scope_identity() is a TRANSACT-SQL instance not supported by MS Access.
You could do one of this options:
Don't use autogenerated id columns or no SQL standard fields.
Use a supported hibernate database insted of MS Access Hibernate doc.
Create your own hibernate dialect to support MS Access or use a thirdparty one to provide the special characteristics of MS Access.
Related to How can I use hibernate with MS Access?
I am creating a basic hibernate application for employee table in which I am adding, updating, deleting and displaying the record with the help of ManageEmployee class.
Actually, ManageEmployee is my test class and i am using Employee.java and Employee.hbm.xml file to do above things.
Details:
Database: Oracle 11 g
Hibernate version: hibernate-release-4.3.8.Final
Java Version: Java 1.8
Employee Table Details:
USER_ID NUMBER(15,0) No 1 1
FIRST_NAME VARCHAR2(20 BYTE) Yes 2
LAST_NAME VARCHAR2(20 BYTE) Yes 3
SALARY NUMBER(10,0) Yes 4
Error Log: you can see in the log that error is coming 3 times because I am adding Employee object 3 times in ManageEmployee.java class with addEmployee(...) method so I am assuming that problem is with the sequence generator for the column id.
Here I am using naive generator.
i.g.
Integer empID1 = ME.addEmployee("Zara", "Ali", 1000);

Employee class is missing a sequence generator so hibernate cannot insert the row.
it should be something like this which increase the id count column by 1:
#Id
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQUENCE1")
#SequenceGenerator(name="SEQUENCE1", sequenceName="SEQUENCE1", allocationSize=1)
private int user_id;
after read up on Oracle sequences and how they function, as well as telling Hibernate that you are using a SEQUENCE (section 5.1.2.2.4) rather than a native generator, I have fixed my errors.
I have created a sequence in oracle database by the below query and updated my hbm.xml file
CREATE SEQUENCE TAB_CUSTOMER_SEQ
START WITH 1
MAXVALUE 999999999999999999999999999
MINVALUE 1
NOCYCLE
CACHE 20
NOORDER;
<id name="user_id" type="int" column="user_id">
<generator class="sequence">
<param name="sequence">TAB_CUSTOMER_SEQ</param>
</generator>
</id>
You didn't create a sequence for table EMPLOYEE to generate automatic USER_ID. This is your problem. So now you need to create a sequence for table EMPLOYEE in both DATABASE and your mapping file
try this:
<generator class="sequence"> <param name="sequence_name">SEQUENCE_NAME</param></generator>
The value for param was changed from just "sequence" to "sequence_name".
In my case I forget to add schema parameter in #SequenceGenerator(name = "TADDRESS_SEQ", sequenceName = "TADDRESS_SEQ", schema = "source", allocationSize = 1)
I am trying to implement inheritance using hibernate and using simple program
Well I am declaring a class of person having four attributes-age,sex,name,id(which is auto generated)
Now I have two classes inheriting the base class
The first class is native where one attribute is there that defines pincode whereas the other class is foreign where psotcode is defined
Following is my whole code
person.java
package com;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class Person {
private String Name;
private int age;
private String sex;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private String id;
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
}
native.java
package com;
import javax.persistence.Entity;
#Entity
public class Native extends Person {
private int pincode;
public int getPincode() {
return pincode;
}
public void setPincode(int pincode) {
this.pincode = pincode;
}
}
foreign.java
package com;
import javax.persistence.Entity;
#Entity
public class Foreign extends Person {
private String postcode;
public String getPostcode() {
return postcode;
}
public void setPostcode(String postcode) {
this.postcode = postcode;
}
}
mainclass.java
package com;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
public class Classmain {
public static void main(String args[])
{
Person person = new Person();
person.setName("krish");
person.setSex("M");
person.setAge(23);
Native native = new Native();
native.setPincode(201545);
native.setAge(23);
native.setName("victor");
native.setSex("M");
Foreign foreign = new Foreign();
foreign.setPostcode("sfadfas0");
foreign.setName("michelle");
foreign.setAge(31);
foreign.setSex("F");
SessionFactory sessionfactory = new AnnotationConfiguration()
.configure().buildSessionFactory();
Session session = sessionfactory.openSession();
session.beginTransaction();
session.save(person);
session.save(foreign);
session.save(native);
session.getTransaction().commit();
session.close();
}
}
Following is my hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

What could be the reason?
OK, I found your error, but you should have seen in your logs the previous errors:
ERROR: HHH000389: Unsuccessful: create table Person (DTYPE varchar(31) not null, id varchar(255) not null auto_increment, Name varchar(255), age integer not null, sex varchar(255), pincode integer, postcode varchar(255), primary key (id))
07-jun-2013 17:17:35 org.hibernate.tool.hbm2ddl.SchemaExport perform
ERROR: Incorrect column specifier for column 'id'
If you look at the definition of id, you are trying to declare an auto-increment field with a String variable in Person class. Change it with int and it will work perfectly.
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
A unique table named Person is created and data are inserted correctly.
Try to add #Table(name="table_name") annotations to inherited entities.
