DELPHI的HELP中有例子呀，用Book呀，循环取每个BookMark的指针

Answer 2

tmp := TStringList.Create;
if DBGrid.SelectedRows.Count > 1 then begin
      for i := 0 to DBGrid.SelectedRows.Count - 1 do begin
        query1.GotoBook(pointer(DBGrid1.SelectedRows.Items[i]));
        tmp.Add(Query1.fieldbyname('yourfield').asString);
      end;
    end;
