Api criteria, where 1 <> 1

Question

I want the query to not return any values. I can't just not query the database, so I would like to add some unreachable conditions for predicates, something like "where 1 <> 1". But CriteriaBuilder.equal () does not allow this. Is there a way to achieve the goal?

Thank.
