|
Fills a delta dataset with all nested dataset field values.
procedure FetchDetails(Source: TDataSet; Delta: TDataSet); override;
virtual __fastcall FetchDetails(TDataSet Source, TDataSet Delta);
FetchDetails is used internally to fetch the current values of any nested datasets when the provider is executing its RowRequest method. Source is a source dataset that has the current values for all fields. Delta is a delta dataset that must be updated so that its nested detail fields match the values in Source.
