About Renderable interface

Hibernate ORM
1

Hello,
In Hibernate 5.6, the Renderable interface supported dynamically rendering HQL fragments and converting them into predicate objects. This allowed me to conveniently use string-based expressions like:
exists(select 1 from A a where a = root_.aid and a.f1 = :f1 and ...).

For simple conditions, I could construct predicates using the Criteria API. For complex nested conditions, I could easily write HQL fragments as strings. By implementing Renderable, predicates were automatically constructed with secure parameter binding.

In version 6.6, I haven’t found a similar implementation approach. Could you advise if there’s an equivalent alternative to achieve this requirement? Alternatively, is such functionality planned for future releases?

Thank you.

This was never “supported”, but rather an unfortunate implementation detail. No such feature is planned for future Hibernate ORM versions. You will have to construct these fragments through the JPA Criteria API.
