我正在尝试复制一些旧的Excel模板,它们设置的方式并不理想,但我将它们用作练习。
在excel表中有一个如下所示的列:
|--Week and dates--|
|------------------|
|Week 291214_040115|
|Week 050115_110115|
|Week 120115_180115|
|...etc............|
|...etc............|
|...etc............|
|...etc............|
|Week 030717_090717|
|Week 100717_160717|
使用下面的代码我尝试重新创建上面的代码但是我遇到了几个问题。
Declare @sDate date,
@eDate date;
Select @sDate = '2015-01-01',
@eDate = '2017-07-31';
;with cte as
(
select @sDate StartDate,
DATEADD(wk, DATEDIFF(wk, 0, @sDate), 6) EndDate
union all
select dateadd(ww, 1, StartDate),
dateadd(ww, 1, EndDate)
from cte
where dateadd(ww, 1, StartDate)<= @eDate
)
select concat(StartDate,'_',EndDate) as date
from cte
OPTION (MAXRECURSION 0)
它产生的输出是:
|------------Dates-------------|
|2015-01-01_Jan 4 2015 12:00AM|
|2015-01-08_Jan 11 2015 12:00AM|
|2015-01-15_Jan 18 2015 12:00AM|
|2015-01-22_Jan 25 2015 12:00AM|
|2015-01-29_Feb 1 2015 12:00AM|
|2015-02-05_Feb 8 2015 12:00AM|
我没有连接字符串&#34;周&#34;进入脚本,但基本上我如何让脚本看起来更像excel模板表,而不像我自己的版本。
答案 0 :(得分:0)
您可以更改以下选项:
select concat('Week ',Format(StartDate, 'ddMMyy'),'_',Format(dateadd(day,6,StartDate),'ddMMyy')) as date
from cte
