Question

我需要在SQL Server中找到两个日期之间的日期。

where 
    startdate = '2015-12-04 00:00:00.000' 
    and enddate = '2015-12-07 00:00:00.000'

结果应为

2015-12-04 00:00:00.000
2015-12-05 00:00:00.000
2015-12-06 00:00:00.000
2015-12-07 00:00:00.000

Answer 1

尝试：

DECLARE @Date1 DATE, @Date2 DATE
SET @Date1 = '20151204'
SET @Date2 = '20151210'

SELECT DATEADD(DAY,number+1,@Date1) [Date]
FROM master..spt_values
WHERE type = 'P'
AND DATEADD(DAY,number+1,@Date1) < @Date2

或者：

declare @startDate date;
declare @endDate date;

select @startDate = '20151204';
select @endDate = '20151210';

with interdate as
(
  select dt = dateadd(dd, 1, @startDate)
  where dateadd(dd, 1, @startDate) < @endDate
  union all
  select dateadd(dd, 1, dt)
  from interdate
  where dateadd(dd, 1, dt) < @endDate
)
select *
from interdate

Answer 2

这将在sqlserver 2005中起作用：

DECLARE @startdate datetime 

DECLARE @enddate datetime

SELECT @startdate ='2015-12-04', @enddate='2015-12-07'

;WITH N(N)AS 
(SELECT 1 FROM(SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1)M(N)),
tally(N)AS(SELECT ROW_NUMBER()OVER(ORDER BY N.N)FROM N,N a,N b,N c,N d,N e,N f)
SELECT top (datediff(d, @startdate, @enddate) + 1) 
  dateadd(d, N - 1, @startdate)
FROM tally

结果（我删除了时间段）：
