Replicate data from Oracle 10g to SQL 2008?

Hi.,

I need a 'Wrapper.cs' file which takes care of the Database connection ( Oracle 10g) where

i can just call the method with my SQL Query

(eg)

Gridview1.DataSource = SampleWrapper.ExecuteDatatable("THE SQL QUERY");

Gridview1.DataBind();

Hello,

Here is my SP:

create or replace
PROCEDURE ZGETUSERSSIGNONS (vUid IN VARCHAR2, p_getuserssignon_recordset1 OUT SYS_REFCURSOR) AS
BEGIN
 Open p_getuserssignon_recordset1 for
 SELECT Distinct(Userid), UserPassword, SecurityLevel, ActiveStatus
FROM ZSIGNON
WHERE substr(UserId,1,2) <> vUid
Order By UserId;
END ZGETUSERSSIGNONS;

I would like to run this SP from code and fill a gridview with the result. 

I am not sure how to go about this, as I have found several different examples, other than the one I  think I need.

I am using the oracle data provider and I have an input parameter (vUid, which will equal "zz").

First question. When filling a gridview with a result set from a stored procedure should the recordset OUT be defined as a REFCURSOR (like i did above)? 

Second:

Do you have example code as to how to execute the SP and fill a gridview?  I keep trying different variations of code i've found on the internet without any success other than getting more confused.

(I am using VS 2005, VB).

Thank you.

I have succeffuly Imported the ADF and have also successfully created a Business Data Column. But when I try to query data , I get the following error

An error occurred while retrieving data from Oracle Instance. Administrator, see the server log for more information

And this is what I found in the Application Logs
A Metadata Exception was constructed in App Domain '/LM/W3SVC/81256521/ROOT-1-129217212004078822'. The full exception text is: LobSystem could not be found using criteria 'id=476'.
