editing record moves to the last in TClientDataSet
Editing a record in a TClientDataSet, causes it to move to the last. It should keep the current position!!!
(* edit recond n.10 *)
Table3.RecNo:=10;
Table3.Edit;
Table3.Fields[1].AsInteger
Table3.Post;
(* close and reopen the table *)
Table3.Close;
Table3.Open;
(* now the 10th record moved to last!!!! *)

Hi!
Adding an index optimal to a sertain query speeds the retrieval of
the data. Same goes for a table objects.
If space allocations for the index is well designed then adding an insert
will have minimal affects on update and insert to the table.
