Hibernate ORA-00932: inconsistent datatypes: expected NUMBER got BINARY

I'm trying to map an Oracle database with Java using Hibernate but I'm facing an issue. Here is the code :
Java app :
package guival.tp3.bdd;
import java.time.LocalDate;
import org.hibernate.*;
public class Scenariste extends Personne {
private int idScenariste;
public int getIdScenariste() {
return idScenariste;
}
public void setIdScenariste(int idScenariste) {
this.idScenariste = idScenariste;
}
}
public class Test {
public static void main(String[] args) {
Session uneSession = HibernateUtil.getSessionFactory().openSession();
Transaction uneTransaction = uneSession.beginTransaction();
Scenariste scenar = new Scenariste();
scenar.setDateNaissance(LocalDate.now());
scenar.setNom("fefef");
scenar.setPrenom("fefzefzfz");
uneSession.save(scenar);
uneTransaction.commit();
uneSession.close();
HibernateUtil.shutdown();
}
}
Hibernate config file :
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:#localhost:1521/system</property>
<property name="hibernate.connection.username">---</property>
<property name="hibernate.connection.password">---</property>
<property name="dialect">org.hibernate.dialect.OracleDialect</property>
<property name="hibernate.c3p0.min_size">5</property>
<property name="hibernate.c3p0.max_size">20</property>
<property name="hibernate.c3p0.timeout">300</property>
<property name="hibernate.c3p0.max_statements">50</property>
<property name="hibernate.c3p0.idle_test_period">3000</property>
<!-- SQL to stdout logging -->
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>
<mapping resource="guival/tp3/bdd/Scenariste.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Hibernate Scenariste table mapping file :
<hibernate-mapping>
<class name="guival.tp3.bdd.Scenariste" table="SCENARISTE">
<id name="idScenariste" column="ID_SCENARISTE" type="integer" unsaved-value="0">
<generator class="sequence">
<param name="sequence">SEQ_SCENARISTE</param>
</generator>
</id>
<property name="nom">
<column name="NOM" sql-type="VARCHAR2(50)"/>
</property>
<property name="prenom">
<column name="PRENOM" sql-type="VARCHAR2(50)"/>
</property>
<property name="dateNaissance">
<column name="DATE_NAISSANCE" sql-type="DATE"/>
</property>
</class>
</hibernate-mapping>
And the SCENARISTE table looks like that :
I also made a trigger in the database to increment the ID_SCENARISTE column.
When I run this code I have this error : ORA-00932: inconsistent datatypes: expected NUMBER got BINARY
Here are the last lines of the Hibernate log when the error occurs :
Hibernate:
select
SEQ_SCENARISTE.nextval
from
dual
Hibernate:
/* insert guival.tp3.bdd.Scenariste
*/ insert
into
SCENARISTE
(NOM, PRENOM, DATE_NAISSANCE, ID_SCENARISTE)
values
(?, ?, ?, ?)

déc. 02, 2018 6:48:55 PM org.hibernate.util.JDBCExceptionReporter logExceptions

I'm using Hibernate 3.2.0.cr5 and Java SE 8.
Do you have a solution ?

Try removing the data type like this
<id name="idScenariste" column="ID_SCENARISTE" unsaved-value="0">
<generator class="sequence">
<param name="sequence">SEQ_SCENARISTE</param>
</generator>
</id>

Unable to run basic hibernate 5 program

I am trying to run the program given in hibernate tutorial(basic).But I am facing error. Surprisingly, there are very few error logs displayed in the console. If anyone can show me where I am going wrong, I will be grateful. I have spent lot of time trying to resolve it before posting it here.

I have made some changes to the hibernate.cfg.xml and it started working.The modified xml is as below :
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:#localhost:1521:XE</property>

<property name="hbm2ddl.auto">create</property>
<mapping resource="org/hibernate/tutorial/hbm/Event.hbm.xml"/>
</session-factory>
</hibernate-configuration>
The change I done in this xml is modifying the connection url :
<property name="connection.url">jdbc:oracle:thin:#localhost:1521:XE</property>

getGeneratedKeys() support is not enabled error in Hibernate 5.0.0.CR2

I'm trying to connect to Oracle and I'm getting this error in Hibernate-5.0 even though I have enabled this property in configuration.

<property name="lastName" column="last_name" type="string" />
<property name="salary" column="salary" type="integer" />

I have tried many times but not seem to resolve. Where I'm going wrong here? Any pointers is a great help. Thanks in advance.

Not sure if this is an issue with the Hibernate version, because when I change the dependency version to 4.3.9.Final from 5.0.0.CR2 in POM then it is working fine.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.3.9.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.3.9.Final</version>
</dependency>

I don't think it is your code that is the problem, but Oracle.
According to comments in the Oracle9Dialect, Oracle does not support returning the generated key, not like any other database does it.

Hibernate exception

im new to hibernate! i have followed the netbeans tutorial on creating a hibernate enabled application. after sucessfully creating a database in mysql workbench i reversed engineered the pojos etc and then tried to run a simple query(from Course) and got the following

The problem is not really Course, the problem is the many-to-many association between Course and Module, the later being not recognized as a mapped class. Do you see any noticeable error messages when you create the SessionFactory? Nothing about Module? Can you show Module.hbm.xml?

Hibernate 3: unable to query PostgreSQL database

I am setting up a project using Hibernate 3.3.1 GA and PostgreSQL 8.3. I've just created a database, the first table, added one row there and now configuring Hibernate.
However, even the simplest query:
Criteria criteria = session.createCriteria(Place.class);
List result = criteria.list();
could not be executed (empty list is returned though there is one record in the database). I looked at the PostgreSQL logs to see:
2008-09-17 22:52:59 CEST LOG: connection received: host=192.168.175.1 port=2670
2008-09-17 22:52:59 CEST LOG: connection authorized: user=... database=...
2008-09-17 22:53:00 CEST LOG: execute <unnamed>: SHOW TRANSACTION ISOLATION LEVEL
2008-09-17 22:53:02 CEST LOG: could not receive data from client: Connection reset by peer
2008-09-17 22:53:02 CEST LOG: unexpected EOF on client connection
2008-09-17 22:53:02 CEST LOG: disconnection: session time: 0:00:03.011 user=... database=... host=192.168.175.1 port=2670
I wrote a simple program using plain JDBC to fetch the same data and it worked. PostgreSQL logs in this case look like this (for comparison):
2008-09-17 22:52:24 CEST LOG: connection received: host=192.168.175.1 port=2668
2008-09-17 22:52:24 CEST LOG: connection authorized: user=... database=...
2008-09-17 22:52:25 CEST LOG: execute <unnamed>: SELECT * from PLACE
2008-09-17 22:52:25 CEST LOG: disconnection: session time: 0:00:00.456 user=... database=... host=192.168.175.1 port=2668
Hibernate debug log does not indicate any errors. If I take the query listed in the logs:
15:17:01,859 DEBUG org.hibernate.loader.entity.EntityLoader: Static select for entity com.example.data.Place: select place0_.ID as ID0_0_, place0_.NAME as NAME0_0_, place0_.LATITUDE as LATITUDE0_0_, place0_.LONGITUDE as LONGITUDE0_0_ from PLACE place0_ where place0_.ID=?
and execute it agains the database in the psql, it works (this means that Hibernate has generated a proper SQL).
Below is the Hibernate configuration:
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.url">jdbc:postgresql://192.168.175.128:5433/...</property>
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<property name="hibernate.connection.username">...</property>
<property name="hibernate.connection.password">...</property>
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.use_outer_join">true</property>
<mapping resource="com/example/data/Place.hbm.xml"/>
</session-factory>
</hibernate-configuration>
...and the mapping file:
<hibernate-mapping package="com.example.data">
<class name="com.example.data.Place" table="PLACE">
<id column="ID" name="id" type="java.lang.Integer">
<generator class="native"/>
</id>
<property column="NAME" name="name" not-null="true" type="java.lang.String">
<meta attribute="use-in-tostring">true</meta>
</property>
<property column="LATITUDE" name="latitude" not-null="true" type="java.lang.Float">
<meta attribute="use-in-tostring">true</meta>
</property>
<property column="LONGITUDE" name="longitude" not-null="true" type="java.lang.Float">
<meta attribute="use-in-tostring">true</meta>
</property>
</class>
</hibernate-mapping>
Googling for unexpected EOF log entry was not friutful. Any ideas, community?

After applying debugger to the Hibernate code, it is fixed!
It is not visible in the question's text, but the problem is that Place passed to the createCriteria() method is from another package, not com/example/data, specified in the configuration XML files.
Hibernate invokes Class.isAssignableFrom(), and if false is returned, it exits silently, thus breaking the connection. I will open a ticket for Hibernate developers on this matter.
