Spring Data JPA NamedStoredProcedureQuery Multiple Out Parameters

Question

I have a simple stored procedure I\'m using to test out Spring Data JPA Stored Procedure feature.

create or replace procedure plus1inout (arg in int,res1 out int         


        

Answer 1

You can specify to return one of the multiple out params with the outputParameterName param in the @Procedure annotation like this:

@Repository
public interface AdjudConverDateSPRepository extends JpaRepository {
    @Procedure(name = "plus1", outputParameterName = "res2")
    Integer plus1(@Param("arg") Integer arg);
}

UPDATE 2019-06-24:

Multiple out parameters is now supported in Spring Data JPA 2.2-RC1 https://spring.io/blog/2019/06/17/spring-data-moore-rc1-and-lovelace-sr9-released

https://jira.spring.io/browse/DATAJPA-707

The interface method just needs to have a Map return type so each out param can be accessed by key name:

@Repository
public interface AdjudConverDateSPRepository extends JpaRepository {
    @Procedure(name = "plus1")
    Map plus1(@Param("arg") Integer arg);
}
