ท่านใดพอทราบวิธีเรียกใช้งาน Procedure ของ Oracle ผ่าน vb.net บ้างครับ

        Dim myCMD As New OracleCommand()
        myCMD.Connection = Oraclecon
        myCMD.CommandText = "curspkg_join.open_join_cursor1"
        myCMD.CommandType = CommandType.StoredProcedure
        myCMD.Parameters.Add(New OracleParameter("n_empno", OracleType.Number)).Value = 123
        myCMD.Parameters.Add(New OracleParameter("io_cursor", OracleType.Cursor)).Direction = ParameterDirection.Output

Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click

        Me.UseWaitCursor = True
        Me.Cursor = Cursors.WaitCursor

        Dim myCMD As New OracleCommand("pck_delete_insert_report", conn)
        myCMD.Connection = conn
        myCMD.CommandText = "pck_delete_insert_report.p_delete_insert"
        myCMD.CommandType = CommandType.StoredProcedure
        myCMD.Parameters.Add(New OracleParameter("cursor_cs", OracleType.Cursor)).Direction = ParameterDirection.Output

        Try
            conn.Open()
            Dim myCMDReader As OracleDataReader = myCMD.ExecuteReader()

            myCMDReader.NextResult()

        Catch ex As Exception
            System.Console.WriteLine("Exception: {0}", ex.ToString())
        End Try

        conn.Close()
    End Sub
End Class
