    connOra)             connOra.Open()             myReader = comm.ExecuteReader()             'Check if Query Returns value             If myReader.HasRows Then                 While myReader.Read()                     If Not myReader(0) Is DBNull.Value Then                         maxIndex = myReader(0)                         Dim comm1 As New Data.OracleClient.OracleCommand("UPDATE schema.APP_PARMS a SET a.cur_val = :requestID
    WHERE UPPER(a.parm_nm) = 'ID'"
