Hi,
I'm new to JPA. In SQL, there is "*" which means any all. For example,
SELECT * FROM PRODUCT WHERE CATEGORY=*
In JPA, the query is:
Query query = entityManager.createQuery("select o from Product o WHERE o.category = :value");
query.setParameter("category", category);
How can I set category to any category in JPA?
