Problem with OPEN My_Cursor FOR SELECT ...

Question

Please, I need some help here. I'm developing an ASP NET application with Crystal Reports and Oracle 9i as DB.
I'm desining a report. I use a Stored Procedure (in a package). I know that in order to CR be able to read the stored procedure, I have to use Cursor in this way: OPEN My_Cursor FOR SELECT * FROM My_Table;
The problem is that I need to do other sub-queries to get the names of 3 people (from TBL_TWO) and show them in my Cursor (from TBL_ONE). How can I do it? I tried as my example, but I get error when try to connect from ASP NET: "ORA-24338 statement handle not executed"
Apparantly, CR needs to read just only OPEN My_Cursor FOR ... Is there any way to resolve this problem?
PROCEDURE SP_REP_OP_03 (My_CURSOR OUT MY_REF_CURSOR,
i_Cod_OP IN INTEGER)
IS
v_id_1 char(8);
v_Names_1 varchar(25);
v_id_2 char(8);
v_Names_2 varchar(25);
v_id_3 char(8);
v_Names_3 varchar(25);
BEGIN
SELECT TWO.Id, PER1.Names -- may or may not exist
INTO v_id_1, v_Names_1
FROM TBL_TWO TWO, PADRON.PADRON PER1
WHERE TWO.Cod_OP = i_cod_op AND
TWO.Cod_Rep = '01' AND
TWO.Id = PER1.Id;
IF v_id_1 IS NULL THEN
v_id_1:= '';
v_Names_1:= '';
END IF;
SELECT TWO.Id, PER1.Names -- may or may not exist
INTO v_id_2, v_Names_2
FROM TBL_TWO TWO, PADRON.PADRON PER1
WHERE TWO.Cod_OP = i_cod_op AND
TWO.Cod_Rep = '02' AND
TWO.Id = PER1.Id;
IF v_id_2 IS NULL THEN
v_id_2:= '';
v_Names_2:= '';
END IF;
SELECT TWO.Id, PER1.Names -- may or may not exist
INTO v_id_3, v_Names_3
FROM TBL_TWO TWO, PADRON.PADRON PER1
WHERE TWO.Cod_OP = i_cod_op AND
TWO.Cod_Rep = '03' AND
TWO.Id = PER1.Id;
IF v_id_3 IS NULL THEN
v_id_3:= '';
v_Names_3:= '';
END IF;
-- I tried to "attach" v_id and v_Names to My_Cursor, but CR can't get it
OPEN My_CURSOR FOR
SELECT ONE.Cod_Exp AS Cod_Exp,
ONE.Cod_Exp_OP AS Cod_Exp_OP,
ONE.Cod_OP AS Cod_OP,
ONE.cod_ficha AS cod_ficha,
v_id_1 As id_1 ,
v_Names_1 As Names_1,
v_id_2 As id_2 ,
v_Names_2 As Names_2,
v_id_3 As id_3 ,
v_Names_3 As Names_3,
FROM TBL_ONE ONE
WHERE OP.Cod_op = i_Cod_op;
END SP_REP_OP_03;

Why can't you just have a single SQL query that outer-joins the tables and returns the values you need? It looks like it should start in TBL_ONE and outer-join three times to TBL_TWO and PADRON, perhaps something like:
SELECT one.cod_exp
     , one.cod_exp_op
     , one.cod_op
     , one.cod_ficha
     , id1.id AS id_1
     , per1.names AS names_1
     , id2.id AS id_2
     , per2.names AS names_2
     , id3.id AS id_3
     , per3.names AS names_3
FROM   tbl_one one
     , tbl_two id1
     , padron.padron per1
     , tbl_two id2
     , padron.padron per2
     , tbl_two id3
     , padron.padron per3
WHERE  one.cod_op = i_cod_op
AND    id1.cod_op (+)= one.cod_op
AND    id1.cod_rep (+)= '01'
AND    per1.id (+)= id1.id
AND    id2.cod_op (+)= one.cod_op
AND    id2.cod_rep (+)= '02'
AND    per2.id (+)= id2.id
AND    id3.cod_op (+)= one.cod_op
AND    id3.cod_rep (+)= '03'
AND    per3.id (+)= id3.id;
