[JPQL] Howto pass proprietary SQL keywords to the DB?

Question

Hi,
Is there any way to pass proprietary SQL keywords to the database without the JPA implementation complaining?
In my case I would like to use PostgreSQL's "OFFSET" and "LIMIT" keywords in a subquery, however Hibernate complains because it doesn't understand the OFFSET keyword.
Thank you in advance, Clemens

I would really try to avoid native queries if possible somehow :/Is it really such a big concern? I can think of two reasons that it would be:
- you use something like HSQL as a drop-in database for unit testing purposes
- you want to keep the option open to switch DBMS implementation
The first I can understand but is easily circumvented with some mock code override magic, the second I would say is no issue as it is a very bad idea to switch DBMS anyway, even if you use an ORM layer that technically makes it possible.
Just a thought, I really wouldn't spend ages trying to work around a problem just because maybe perhaps you never know somewhere in some unknown point in time you might just need to spend 5 minutes to locate and change a line of code.
