Component dataset.

Pascal
property Dataset: TDataset;
Description

Defines the component dataset. Setting the Dataset to nil will set all TVecColumn.FieldName to null string.

Notes

Set the Dataset property before you set the TVecColumn.FieldName property.

Example

Connect MtxDataSet to Table1 and read numeric values from two fields. 

 

procedure TForm1.FormCreate(Sender: TObject); begin MtxDataSet.Dataset := Table1; MtxDataSet.VecColumns.Clear; with MtxDataset.VecColumns.Add do begin FieldName := 'ShipDate'; ReadWriteMode := wmColumn; end; MtxDataSet.ReadDataset; end;
void __fastcall TForm1::FormCreate(TObject *Sender) { MtxDataSet->Dataset = Table1; MtxDataSet->VecColumns->Clear(); TVecColumn *col; col = MtxDataSet->VecColumns->Add(); col->FieldName = "ShipDate"; col->ReadWriteMode = wmColumn; MtxDataSet->ReadDataset(false); }
