在sql中创建日历

Question

我们在数据库中使用查找表来分组数周，数月和数年。可悲的是，制作它的那个人早就不见了，日历在年底就用尽了！所以我真的需要找到一种方法来添加它！它的设置如下：

我在sql（MS2008）中表现不是很好，说实话，我已经把它搞砸了，我们不能设置任何新东西，因为一切都围绕着这个！

你可以这样做，但我不明白为什么你的日历从三月开始？

declare @Date_Start date, @Date_End date

select @Date_Start = '20130101'
select @Date_End = '20131231'

;with
CTE_Dates as (
    select @Date_Start as [Date]
    union all
    select dateadd(dd, 1, [Date])
    from CTE_Dates
    where [Date] < @Date_End
),
CTE_Calendar as (
    select
        [Date],
        datename(dw, [Date]) as [Day],
        datepart(ww, [Date]) as [Week],
        datepart(mm, [Date]) as [MonthID],
        dateadd(mm, datediff(mm, 0, getdate()), 0) as [Month],
        datepart(yy, [Date]) as [YearID],
        dateadd(yy, datediff(yy, 0, getdate()), 0) as [Year],
        datepart(qq, [Date]) as [QuarterID],
        dateadd(qq, datediff(qq, 0, getdate()), 0) as [Quarter]
    from CTE_Dates
)
select
    row_number() over (order by [Date]) + @Start_ID - 1 as ID,
    *
from CTE_Calendar
option (maxrecursion 0)
