JPQL: The state field path cannot be resolved to a valid type

Question

I can\'t make this query work:

Query query = eManager.createQuery(\"select c FROM News c WHERE c.NEWSID = :id\",News.class);
        return (News)query.setPara         


        

Answer 1

That happens because News entity does not have persistent attribute named NEWSID. Names of the persistent attributes are case sensitive in JPQL queries and those should be written with exactly same case as they appear in entity.

Because entity have persistent attribute named newsId, that should also be used in query instead of NEWSID:

select c FROM News c WHERE c.newsId = :id
