wrong number or types of arguments while calling Stored Proc - oracle

Question

I am calling Stored Proc from Spring Data JPA :
Procedure is:
create or replace procedure GET_LATEST_GC (arg1 IN VARCHAR2, res1 OUT VARCHAR2, res2 OUT VARCHAR2)
AS
BEGIN
DELETE FROM GC_T WHERE id = arg1;
COMMIT;
BEGIN
SELECT gc.NAME, s.SIP INTO res1, res2
FROM GC_T gc, STAFF_T s WHERE s.id = gc.id
AND START_TIME = (SELECT MAX(START_TIME) FROM GC_T);
EXCEPTION
WHEN others THEN
res1 := '';
END;
END;
Spring Data JPA code
//Repository
public interface ActiveDao extends JpaRepository<GcT,Integer> {
#Procedure(procedureName="GET_LATEST_GC")
Object[] plus1(#Param("arg1") String arg1);
}
//Entity
#Data
#Entity
#NamedStoredProcedureQuery(name = "GET_LATEST_GC",
procedureName = "GET_LATEST_GC", parameters = {
#StoredProcedureParameter(mode = ParameterMode.IN, name = "arg1", type = String.class),
#StoredProcedureParameter(mode = ParameterMode.OUT, name = "res1", type = String.class),
#StoredProcedureParameter(mode = ParameterMode.OUT, name = "res2", type = String.class)})
#Table(schema = "abc", name = "GC_T")
public class GcT implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Column(name = "ID")
private String id;
#Column(name = "NAME")
private String name;
}
//Call
Object[] activeGCInfo =activeDao.plus1(arg);
Procedure is accepting one parameter and I am also passing 1 argument.Then also I am getting this error:
Hibernate: {call GET_LATEST_GC(?,?)}
ERROR o.h.e.jdbc.spi.SqlExceptionHelper - ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of arguments in call to 'GET_LATEST_GC'\nORA-06550: line 1, column 7:\nPL/SQL: Statement ignored\n
Please let me know where I am doing wrong.
Thank you
Update- Tried to add OUT params also as per suggestion
//Repo
public interface ActiveDao extends JpaRepository<GcT,Integer> {
#Procedure(procedureName="GET_LATEST_GC")
Object[] plus1(#Param("arg1") String arg1,#Param("res1") String res1,#Param("res2") String res2);
}
//Call
Object[] activeGCInfo =activeDao.plus1(arg,"","");
I am sending three args but it is showing me 4 args in error:
Hibernate: {call GET_LATEST_GC(?,?,?,?)} SqlExceptionHelper - ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of
arguments in call to 'GET_LATEST_GC'\nORA-06550: line 1, column
7:\nPL/SQL: Statement ignored\n

Answer 1

Try changing the result from Object[] to Map<String, Object, along with referencing the proc name with name instead of procedureName. Based on the error, I'm not sure that it will fix it. Spring Data JPA does expect a Map as the return value for multiple output params, so each output param can be found as the key in that Map. But I think the main error is that procedureName maps directly to the db, but name= will map to the correct Entity
//Repo
public interface ActiveDao extends JpaRepository<GcT,Integer> {
#Procedure(name="GET_LATEST_GC")
Map<String, Object> plus1(#Param("arg1") String arg1);
}
//Call
Map<String, Object> activeGCInfo =activeDao.plus1(arg);

Here's what happened:
you declared a procedure with 3 parameters: 1 in and 2 out
you said: "Procedure is accepting one parameter and I am also passing 1 argument"
that was the 1st procedure's parameter (arg1 IN)
it results in "PLS-00306: wrong number or types of arguments"
Of course it does; you need to provide 2 more arguments (datatype should be able to accept VARCHAR2 values returned by the procedure).
