Hibernate JPA stored procedure call?

Question

I am using Hibernate JPA. I have below Oracle Stored procedure.

CREATEORREPLACEPROCEDURE PROC_AB
(
      in_name VARCHAR2,
      in_lastname VARCHAR2,
      out_emp_id OUTINTEGER
)

How can I invoke this stored procedure?

Answer 1

Check this SO question:

1. First you define the stored procedure named native query:

   @javax.persistence.NamedNativeQuery(name = "call_proc_ab", query = "{ call PROC_AB(:cmpid,:status,?) }", resultClass = Long.class, hints = {
   @javax.persistence.QueryHint(name = "org.hibernate.callable", value = "true") })
   

2. Then you execute it using:

   TypedQuery<Long> query = entityManager.createNamedQuery("call_proc_ab", Long.class); 
   query.setParameter("cmpid",cmpid); 
   query.setParameter("status",status); 
   Long empId = query.getSingleResult();
