Issue
I made a Postgres stored procedure:
CREATE OR REPLACE FUNCTION GetUser(ipUserId integer)
RETURNS setof users AS $$
BEGIN
IF ipUserId is null THEN
return query select * from users A order by modifieddate desc;
END IF;
return query select * from users where iduser = ipUserId;
END;
$$ LANGUAGE plpgsql;
I tried to use it in java like this:
StoredProcedureQuery query = entityManager.createStoredProcedureQuery("GetUser").
registerStoredProcedureParameter("ipUserId",
Integer.class, ParameterMode.IN)
.registerStoredProcedureParameter("users",
List.class, ParameterMode.OUT)
.setParameter("postId", 1);
or
StoredProcedureQuery query = entityManager.createStoredProcedureQuery("GetUser")
.registerStoredProcedureParameter(1,void.class, ParameterMode.REF_CURSOR)
.registerStoredProcedureParameter(2,Integer.class, ParameterMode.IN)
.setParameter(2, ipIdUser);
I want to store the result in a List.
What and how should i do, because i'm getting all kind of errors?
Update :
Those are the errors :

Solution
I found a much simple solution, just make a SQL Query to call the procedure with hibernate.
String SqlString = "select * from GetUser({0})";
if (ipIdUser == null )
SqlString = MessageFormat.format(SqlString, "NULL");
else
SqlString = MessageFormat.format(SqlString, ipIdUser);
LOGGER.info("SqlSting =" + SqlString);
return entityManager.createNativeQuery(SqlString, User.class)
.getResultList();
