JPA中的存储过程

Question

I have one procedure in data base it returns list of objects when i try to iterate that result i am getting only one row multiple times.it is not ponting to next record in loop,

here is my code,

Query nativeQuery = entityManager.createNativeQuery("call getdata(?, ?, ?, ?)", Detail.class); 
List<Detail>  paymentAnalysisDetails=nativeQuery.getResultList();
for( Detail Details : paymentAnalysisDetails) {
    System.out.println(Details.getStart_date());
}

i getting output::

 start_date   end_date   total_no_of_txns 
 2015-01-01  2015-01-30                10 
 2015-01-01  2015-01-30                10 

but while executing same procedure in mysql output as

start_date  end_date    total_no_of_txns
2015-01-01  2015-01-30  10
2015-02-01  2015-02-30  200

can anyone suggest me

You don't need/have to call stored procedures from the 'createNativeQuery' method because JPA 2.1 supports them now. Check out the following code:

Stored prodcedure (MySQL):

DELIMITER $$
  CREATE PROCEDURE sp_getUsers(inputAge INT)
  BEGIN
    SELECT u.* FROM usertable u WHERE u.age >= inputAge;
  END;
$$

JPA calling:

int age = 10;

StoredProcedureQuery query = em.createStoredProcedureQuery("sp_getUsers", Usertable.class)
.registerStoredProcedureParameter("inputAge", Integer.class, ParameterMode.IN)
.setParameter("inputAge", age);

List<Usertable> userList = query.getResultList();
