 Dim req As DBRequestManager = CreateRequest
   Dim cmd As DBCommand = CreateCommand("select_animal", Array(id))
   Wait For (req.ExecuteQuery(cmd, 0, Null)) JobDone(j As HttpJob)
   If j.Success Then
       req.HandleJobAsync(j, "req")
       Wait For (req) req_Result(res As DBResult)
       'work with result
       req.PrintTable(res)
   Else
       Log("ERROR: " & j.ErrorMessage)
   End If
   j.Release
