Deprecate HQL-specific (JDBC-style) positional parameters
---------------------------------------------------------

                 Key: HHH-7023
                 URL: https://hibernate.onjira.com/browse/HHH-7023
             Project: Hibernate ORM
          Issue Type: Deprecation
          Components: query-hql
            Reporter: Steve Ebersole


Deprecate the Hibernate-specific (JDBC-style) positional parameters in favor of the JPA-style.  

{code}
// HQL positional parameters:
Query q = session.createQuery( "from Cat c where c.name = ?" )
   .setParameter( 1, "Tabitha" )
   ...

// JPQL style:
Query q = em.createQuery( "from Cat c where c.name = ?1" )
   .setParameter( 1, "Tabitha" )
   ...

JPQL style, from Hibernate API:
Query q = em.createQuery( "from Cat c where c.name = ?1" )
   .setParameter( "1", "Tabitha" )
   ... 
{code}

This would allow the following from HQL:
{code}
Query q = session.createQuery( "from Cat c where c.name = ?1" )
   .setParameter( 1, "Tabitha" )
   ...
{code}
