Error calling stored procedure from MFC.

Question

Hello,
I am using MFC to call a stored procedure written in PL/SQL, but when I make the call I get the next error in Spanish:
"No se enlazaron columnas antes de llamar a SQLFetchScroll o SQLExtendedFetch", which more or less in English means:
"No rows were binded before calling SQLFetchScroll or SQLExtendedFetch".
I am using a CRecordset derived class to access the stored procedure. I am unable to find the error.
THE STORED PROCEDURE'S HEADER:
Sp_Int_Ot_Ordendetrabajoalta ( lineatrabajo NUMBER, lv_orden NUMBER, usuario
VARCHAR2, idvehiculo NUMBER, fechamax1 VARCHAR2, resumen VARCHAR2, detalle
VARCHAR2,
coderp VARCHAR2, numtrabrecibidos NUMBER, lv_CODOT VARCHAR2, retorno OUT
INTEGER)
THE .H FOR THE CRECORDSET DERIVED CLASS (Visual Studio 6 comments removed)
class CRecSP : public CRecordset
public:
CRecSP(CDatabase* pDatabase = NULL);
DECLARE_DYNAMIC(CRecSP)
CString m_szSQL;
long m_RETORNO;
virtual CString GetDefaultConnect();
virtual CString GetDefaultSQL();
virtual void DoFieldExchange(CFieldExchange* pFX);
THE .CPP FOR THE CLASS (VS6 comments removed)
IMPLEMENT_DYNAMIC(CRecSP, CRecordset)
CRecSP::CRecSP(CDatabase* pdb) : CRecordset(pdb)
m_RETORNO = 0;
m_nParams = 1;
m_nDefaultType = snapshot;
CString CRecSP::GetDefaultConnect()
return T( DBCONNECTION_STRING );
CString CRecSP::GetDefaultSQL()
return m_szSQL;
void CRecSP::DoFieldExchange(CFieldExchange* pFX)
pFX->SetFieldType(CFieldExchange::outputParam);
RFX_Long(pFX, _T("[retorno]"), m_RETORNO );
USING THE CRECORDSET DERIVED CLASS: (Vars read from EditBoxes as CStrings
and formatted in the SQL)
CRecSP *rec = new CRecSP(&db);
szSQL.Format( "{CALL
FGROT2005.SP_INT_OT_ORDENDETRABAJOALTA(%s,%s,'%s',%s,'%s','%s','%s','%s',%s,'%s',?)}",
szLinea, szOrden, "USER", szIdVeh, szFechaMax, szResumen,
szDetalle, "ERP", "0", szCodOT
rec->m_szSQL = szSQL;
//rec->Open( CRecordset::forwardOnly,szSQL,CRecordset::readOnly );
rec->Open( );
iError = rec->m_RETORNO;
rec->Close();

I am trying to pass parameter to test my procedure but it is giving this error : ORA-06531: Reference to uninitialized collection
ORA-06512: at line 12
Here is example for my test procedure:
declare
v_session_id_tab SESSION_ID_TAB_TYPE;
v_service_type_tab SERVICE_TYPE_TAB_TYPE ;
v_service_location_tab SERVICE_LOCATION_TAB_TYPE ;
v_service_call_name_tab SERVICE_CALL_NAME_TAB_TYPE;
v_service_call_start_time_tab SERVICE_CALL_ST_TAB_TYPE;
v_service_call_end_time_tab SERVICE_CALL_ET_TAB_TYPE;
v_service_call_duration_tab SERVICE_CALL_DUR_TAB_TYPE;
v_status_tab STATUS_TAB_TYPE;
v_notes_tab NOTES_TAB_TYPE;
begin
v_session_id_tab(1) := 1;
v_service_type_tab(1) := 'db';
v_service_location_tab(1) := 'local';
v_service_call_name_tab(1) := 'Name of call';
v_service_call_start_time_tab(1) := SYSDATE;
v_service_call_end_time_tab(1) := SYSDATE;
v_service_call_duration_tab(1) := 100;
v_status_tab(1) := 'Z';
v_notes_tab(1) := 'NOTES';
BULK_INSERTS (v_session_id_tab,v_service_type_tab, v_service_location_tab,v_service_call_name_tab,v_service_call_start_time_tab,v_service_call_end_time_tab,
v_service_call_duration_tab, v_status_tab, v_notes_tab);
end;
I declare all types at schema level.
Please give your comments.
Thank you
