Hi

Here my requirements:

Hibernate version: 2.1.4
Mapping documents: Simple class 'User', native id generator, 3 simple string properties.

Code between sessionFactory.openSession() and session.close():
User user = new User();
user.setXyz1("test1");
user.setXyz2("test2");
user.setXyz3("test3");
session.saveOrUpdate(object); // (1)
session.delete(); // (2)

Full stack trace of any exception that occurs:
net.sf.hibernate.HibernateException: Batch update row count: 0
etc etc.

Name and version of the database you are using:
mysql


It looks like a problem with the Hibernate BatchingBatcher. The batcher class doesn

Please try to give more information, no idea what you mean.

i forget some params.... (awkward)

User user = new User();
user.setXyz1("test1");
user.setXyz2("test2");
user.setXyz3("test3");

Transaction tx = session.beginTransaction();
session.saveOrUpdate(user); // (1)
session.delete(user); // (2)
tx.commit();

the last expression tx.commit() throws the HibernateException: Batch update row count wrong: 0

Is it possible, that Hibernate expects 2 row updates, but executes 0 updates?

Many thanks,
Andr
