Pessimistic lock

[hipa]

I have the table from which I want to get unique values for some entities.

public class UniqueGenerator
{
 @Id
 @Column(...)
 private String id;

 @Column(...)
 private Long currentValue;
 ...
}

Then in data access layer I have to write this code to retrieve next value:

...
gen = entityManager.find(UniqueGenerator.class, MY_GENERATOR_ID);
entityManager.lock(gen, LockModeType.WRITE);
entityManager.refresh(gen);

Long currVal = gen.getCurrentValue();
...

Hibernate translate it to these 3 queries:

1. SELECT .. FROM UNIQUE_GENERATORS WHERE ...
2. SELECT GENERATOR_ID FROM UNIQUE_GENERATORS WHERE ...FOR UPDATE
3. SELECT .. FROM UNIQUE_GENERATORS WHERE ...

Is there any way to make Hibernate doing only one query:

SELECT ... FROM UNIQUE_GENERATORS WHERE ... FOR UPDATE

?
