bugmenot commented on HHH-3497:
-------------------------------

An Integer is 2,147,483,647 which is certainly a reasonable number of rows to have.

> I know the type of the return value of row count with HQL query is Long, to be compatible with JPA. But the Criteria is still return in the type of Integer, not in Long. So if there are a huge amount of data in the database, how can we get the right row count value with Criteria.
> =================================================
> criteria.setProjection(Projections.rowCount());
> Long result = Long.valueOf(criteria.uniqueResult().toString());
> =================================================
> I have to write like that to return the type of Long. But I know it is not real.
