Запись двоичного файла

[Raul]

Используй ADOSteram ('Microsoft ActiveX Data Objects 2.8 Library'.Stream)
Например так

ADORecords := ADOCommand.Execute;
ADOFields := ADORecords.Fields;
ADOField := ADOFields.Item('ImageData');
ADOStream.Mode := 3;
ADOStream.Type := 1;
ADOStream.Open;
ADOStream.Write(ADOField.Value);
ADOStream.SaveToFile('с:\image.jpg');
ADOStream.Close;
