When i call the update(Obj) hibernate give me a error:Batch update returned unexpected row count from update [0]

the following is my code:

customer=customerManager.getCustomerByCustomerId(customerId);

customerManager.saveCustomer(customer);


The DAOImpl:

public boolean saveCustomer(TblCustomerInfo customerInfo) {



getHibernateTemplate().update(customerInfo);
return true;
}

Your update is failing. Either there's no object in the database matching your customer's primary key or you've got a key mapping error.
