sql-server-2008 - CTE 使用 SQL Server 获取两个日期之间的日期

Question

我想获取两个日期之间缺少的日期

说 @maxDate = '2013-01-28'
说 @curDate = GetDate()
我已经写了 CTE 来做到这一点。这是我的 CTE:

create procedure EmpDate  
as  begin  
declare @curDate Date  
set @curDate = GETDATE()  
declare @maxDate Date  
select @maxDate = MAX(EmpAttendance.Sdate)  
from EmpAttendance

;with GetDates As  
(  
select 1 as counter, @maxDate as Date   
UNION ALL  
select counter + 1, DATEADD(day,counter,@maxDate)  
from GetDates  
where DATEADD(day, counter, @maxDate) < @curDate  
)  
select Date from GetDates  
end   
go  

这样做的结果是

Date  
2013-01-28  
2013-01-29  
2013-01-30  

但我想要

2013-01-29  
2013-01-30   

请帮帮我。

改变

select 1 as counter, @maxDate as Date

到

select 1 as counter, DATEADD(day,1,@maxDate) as Date

通过更改 CTE 使其更简单

;with GetDates As  
(  
select DATEADD(day,1,@maxDate) as TheDate
UNION ALL  
select DATEADD(day,1, TheDate) from GetDates  
where TheDate < @curDate  
)
