[[batch-fetching-changes]]
== Batch Fetching and LockMode
When LockMode is greater than READ Hibernate does not execute the batch fetching so existing uninitialized proxies will not be initialized.
This because the lock mode is different from the one of the proxies in the batch fetch queue.
E.g.
`
MyEntity proxy = session.getReference( MyEntity.class, 1 );
MyEntity myEntity = session.find(MyEntity.class, 2, LockMode.WRITE);
`
only the entity with id equals to 2 will be loaded but the proxy will not be initialized.
