OCI 22303 exception - Pass object to type Record in oracle procedure

Question

Recently i had my first encounter with ODP.NET and Oracle. I'm developing a a datalayer that can access a stored procedure on an Oracle database.
The problem i'm having is the following:
I'm using this method to pass my parameters to the procedure: http://www.codeproject.com/KB/cs/CustomObject_Oracle.aspx
I have also attempted this approach:
http://developergeeks.com/article/48/3-steps-to-implement-oracle-udt-in-odpnet
I always get the message (litteraly):
Oracle.DataAccess.Client.OracleException: OCI-22303: type &quote;PAC$WEBSHOP_PROCS"."CUSTOMER_IN_RECTYPE" not found.
It sounds weird to me, but what are the &quotes doing here in the error message I see?
Some code i use:
OracleParameter objParam = new OracleParameter
OracleDbType = OracleDbType.Object,
Direction = ParameterDirection.Input,
ParameterName = "PAC$WEBSHOP_PROCS.P_CUSTOMER_IN",
UdtTypeName = "PAC$WEBSHOP_PROCS.WEBSHOP_PROCS.CUSTOMER_IN_RECTYPE",
Value = card
The information i have about the Oracle procedure:
CREATE OR REPLACE PACKAGE PAC$WEBSHOP_PROCS IS
TYPE CUSTOMER_IN_RECTYPE IS RECORD
(CUS_STO_IDENTIFIER NUMBER(2)
,CUS_IDENTIFIER NUMBER(6)
,CH_IDENTIFIER NUMBER(2)
,CH_CARD_VERSION NUMBER(1)
PROCEDURE PRC$WS_VALIDATE_CARD
(P_CUSTOMER_IN IN PAC$WEBSHOP_PROCS.CUSTOMER_IN_RECTYPE
,P_RETURN_CODE IN OUT NUMBER
Any help to cover my problem would be greatly appreciated.
Thx

Answer 1

The only way to call it as is would be via an anonymous plsql block, where you create the record type inside the block. Interacting with the block via ODP would be limited to scalar values.
Here's a PLSQL example just to demonstrate. Here, v1 and v2 are bind variables of scalar type, which you'd setup/bind via ODP instead of the SQL prompt as I did, but I thought this might keep things simpler for the example.
The other choice would be to write a wrapper procedure that takes type OBJECT that you can call from ODP, and inside that procedure convert them to/from RECORD and call the original procedure.
Hope it helps,
