call Oracle Function from VBScript using ADO

I was looking everywhere and found bits and pieces and never really fully working sample... does anybody have VBScript Sample for calling Oracle Function using ADO, please only VBScript, no VB, no C++, no ASP .... fully working VBScript.

I currently use this driver and would like to keep it, I can use OLE DB but it has to be Microsoft OLE DB for Oracle

Driver={Microsoft ODBC for Oracle}


here is my oracle function

FUNCTION TEST ( GIVEN_DAY DATE, INPUT_NAME VARCHAR2) RETURN NUMBER;



thanks a lot
