此查询将执行此操作：

SELECT 
    PageGroup.Page, 
    IIf(
        (Select First(Page) From PageGroup As T Where T.Page > PageGroup.Page) Is Null,
        CStr([Page] - 1) & " >",
        CStr([Page]) & "-" & (Select Min(Page) - 1 From PageGroup As T Where T.Page > PageGroup.Page)) AS [Page Breakup]
FROM 
    PageGroup;
