If you sort the field name &quot; Forename &quot; in ascending order and the field name &quot; Surname &quot; in descending order, all records will be sorted in ascending order by forename, and then within the forenames, in descending order by surname.
如果把数据字段“名字”升序排序而把数据字段“姓氏”降序排序，那么全部数据条目按名字升序排序并在名字内部再一次按姓氏降序排序。
