I want to return multiple values in my EJB query. The query goes something like this:

SELECT SUM(s.sales) SUM(s.cancels) FROM accounts.

To implement this if I write as below:

Query query = _em.createNamedQuery("Accounts.findAccountData");

Now if I do query.getSingleResult(); how do i retrieve both the values since the ejb finder returns either a single object or a collection?.

Any help is much appreciated

If the result of a query cannot be turned into an object (because it's not an entity and no class / constructor is specified), the result will be an Object[] (a List<Object[]> for multiple results).
