> When you use JPA criteria API, the numeric value are not binded but are directly set in the SQL instead. 
> eq: you have a generated SQL like:
> select ... from ... where age=12;
> instead of 
> select ... from ... where age=?;
> With '12' as parameter.  
> when you test the following code:
> {code:java}
> @Entity
> public class User {
> 	@Id
> 	private int id;
> 	private int age;
>         ...
> }
> {code}
> {code:java}
>     CriteriaBuilder builder=em.getCriteriaBuilder();
>     CriteriaQuery<User> query=builder.createQuery(User.class);
>     Root<User> root=query.from(User.class);
>     query.select(root).where(builder.equal(root.get("age"),12));
>     em.createQuery(query).getResultList();
> {code}
