Using Oracle Store Procedure In Silverlight

I Search Forum and did not find any sample to use oracle SP

for example i have SP Like.

PROCEDURE Get_CLSU_CANPENKA
(
    v_SQL IN  varchar2 ,
    cv_1 IN OUT SYS_REFCURSOR
)
AS
v_SQLTEMP VARCHAR2(2000) := v_SQL;

BEGIN


        OPEN cv_1    FOR  SELECT * FROM CLSU_CANPENKA where rownum <3;
        --        v_SQLTEMP;


   EXCEPTION
     WHEN NO_DATA_FOUND THEN
       NULL;

END Get_CLSU_CANPENKA;

code is like ...

x.ExecuteQueryAsync(query, op =>
            {
                op.Results.ForEach(VWCLSU_CANPENKAs.Add);
                CurrentVWCLSU_CANPENKA = VWCLSU_CANPENKAs.FirstOrDefault();
                RaisePropertyChanged("CurrentVWCLSU_CANPENKA");
            });
