Answer 1

SQL为此目的具有DATEDIFF(datepart,startdate,enddate)函数。

示例：

SELECT DATEDIFF(day,'2014-06-05','2014-08-05') AS DiffDate

结果

61

Answer 3

您需要一个日期表来执行此操作

Declare @start_date datetime = '2016-04-25'
        @end_date datetime = '2016-06-05'

SELECT Min(dt) AS week_start, 
       Max(dt) AS week_end 
FROM   dates_table 
WHERE  date_col > @start_date 
       AND date_col < @end_date 
GROUP  BY Datepart(week, dt), 
          Year(dt) 
ORDER  BY Datepart(week, dt), 
          Year(dt)
