Answer 1

;WITH n(n) AS 
(
  SELECT TOP (14) ROW_NUMBER() OVER (ORDER BY [object_id]) 
  FROM sys.objects ORDER BY [object_id]
)
SELECT Dates = DATEADD(DAY, -n, DATEDIFF(DAY, 0, GETDATE())) FROM n
ORDER BY n;

Answer 2

另一种方式;

;with days(day) as
(
    select getdate() - 1 as day
        union all
    select day - 1
        from days
        where day > dateadd(day, -14, getdate())
)
select cast(day as date) from days

从上一天开始，获取最近14天（2周）的日期表
