What does JPA EntityManager.getSingleResult() return for a COUNT query?

Question

What does EntityManager.getSingleResult() return for a COUNT query?

So.. what is the precise runtime type of foo?

Object foo = em.createQuer         


        

Answer 1

You can return directly integer, rather than a long.

return query.getSingleResult() != null ? Integer.parseInt(query.getSingleResult().toString()) : 0;
