How to check at runtime if a NamedNativeQuery was declared

Question

In Hibernate, is there a way to check if a given @NamedNativeQuery exists before calling: Session.getNamedQuery("queryName");

I am composing the name of the Query at runtime, so I need a way to find if it exists, in order to avoid the following exception:

MappingException: Named query not known: queryName

Use method getNamedParameters() to check the names of all named parameters of the query.

Update: Currently the only way to check whether a named query with a given name exists is calling EntityManager.createNamedQuery(…) . The non-presence of a query can be expressed by throwing an exception.

I need to check if the @NamedNativeQuery has been declared, not the parameters – Andrea Caloni Sep 29 '17 at 13:34
Is it okay to look for the `@NamedNativeQuery` / `@NamedNativeQueries` annotation? It's available at runtime. A hacky solution though. – Tamas Rev Sep 29 '17 at 14:29
