举例来说，清单8中定义的视图主要用于按日期排序。
For example, the view defined in Listing 8 essentially sorts by date.
如前所述(见清单6)，如果您调用SearchAction而没有输入任何标准，就会生成一个包含所有已批准和有效的清单(按日期排序)的结果集。
As explained earlier (listing 6), if you invoke the SearchAction without any criteria produces a result set that contains all approved and valid listings, ordered by date.
还可以按优先级、启动日期和到期时间对任务列表排序。
You can also sort the task list by priority, start date, and due time.
