CTE使用SQL Server获取两个日期之间的日期

Question

我想在两个日期之间获取缺少的日期

说 @maxDate = '2013-01-28'

说 @curDate = GetDate()

我写了CTE来做这件事.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  

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.

Answer 1

更改

select 1 as counter, @maxDate as Date

至

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

尽管改变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  
)
...
