Shares the data belonging to another client dataset. Delphi syntax: procedure CloneCursor(Source :TCustomClientDataSet; Reset: Boolean; KeepSettings: Boolean = False); virtual; C++ syntax: virtual void __fastcall CloneCursor(TCustomClientDataSet* Source, bool Reset, bool KeepSettings = false); Description Call CloneCursor to share the data belonging to another client dataset. Source indicates another BDE client dataset whose data is to be shared. If Source is not a TBDEClientDataSet instance, CloneCursor raises an exception. Reset and KeepSettings determine how to set the values of the following properties and events: Filter, Filtered, FilterOptions, and OnFilterRecord IndexName MasterSource and MasterFields ReadOnly If Reset and KeepSettings are both false, the values of the properties listed above are all set to match the source dataset. If Reset is true, the properties listed above are all cleared. If Reset is false and KeepSettings is true, the properties listed above are not changed. In this case, the application must ensure that existing indexes, providers, and so on are compatible with the cloned data. After calling CloneCursor, the data for the client dataset is the same as the data for Source. Edits performed by either client dataset are reflected in the data of both datasets. Note:Because cloned cursors are shared, changing properties that affect the cursor affect both datasets. For example, setting the ReadOnly property of either dataset will make both datasets read-only.

Ol�Se voc� quer DataSet�s distintos, CloneCursor n�o resolve teu problema, pois cria dois ponteiros para o mesmo ResultSet compartilhadoNesse caso, pode-se copiar atrav�s de um DataSetProvider:[code:1:17e30b8230]cds1.Open;with TDataSetProvider.Create(Self) dobegin  DataSet := cds1;  cds2.Data := Data;  Free;end;[/code:1:17e30b8230]Isso deve funcionar.
