Native query with named parameter fails with “Not all named parameters have been set”

Question

I want to execute a simple native query, but it does not work:

@Autowired
private EntityManager em;

Query q = em.createNativeQuery(\"SELECT count(*) FROM my         


        

Answer 1

You are calling setProperty instead of setParameter. Change your code to

Query q = em.createNativeQuery("SELECT count(*) FROM mytable where username = :username");
em.setParameter("username", "test");
(int) q.getSingleResult();

and it should work.
