Insert a series of dates into sql startdate and enddate inputs - sql

Question

I have this table:
**ID StartDate EndDate**
1 01/01/2012 03/01/2012
2 28/09/2013 02/10/2013
3 12/06/2011 15/06/2011
And I need to have this table:
Date
**ID Date**
1 01/01/2012
1 02/01/2012
1 03/01/2012
2 28/09/2013
2 29/09/2013
2 30/09/2013
2 01/10/2013
2 02/10/2013
3 12/06/2011
3 13/06/2011
3 14/06/2011
3 15/06/2011
I Have Next Sql Code That Retarn The Dates Between The StartDate & The EndDate + StartDate +EndDate :
declare #Start datetime
declare #end datetime
declare #request int
set #Start = '2014-09-28 06:53:04.560'
set #end = '2014-09-29 11:53:04.560'
set #request = 1
;with Dates as (
select #request as reqId,#Start as reqDate
union all
select reqId+1,DATEADD(hh,1,reqDate) from Dates
where reqDate < #end
)
select * from Dates
How Can I Get This Result For A Bulk Of StartDate-EndDate Input?

Answer 1

You can do this by using your source date table as below
declare #request int
set #request = 1
;with Dates as (
SELECT #request as reqId,StartDate as reqDate, EndDate
FROM yourDateTable
UNION ALL
SELECT reqId+1,DATEADD(DAY,1,reqDate),Dates.EndDate
FROM Dates
WHERE DATEADD(DAY,1,reqDate) < EndDate
)
SELECT *
FROM Dates

Answer 2

Use recursive query
CREATE TABLE #ranges
(
Id INT ,
startDate DATE ,
ENdDate DATE
)
INSERT #ranges
( Id, startDate, ENdDate )
VALUES ( 1, '2014-5-2', '2014-5-5' ),
( 2, '2014-8-29', '2014-9-3' ),
( 3, '2014-10-2', '2014-10-8' );
WITH
cte
AS ( SELECT *
FROM #ranges
UNION ALL
SELECT id ,
DATEADD(DAY, 1, startDate) ,
EndDate
FROM cte
WHERE DATEADD(DAY, 1, startDate) <= EndDate
)
SELECT Id ,
startDate Date
FROM cte
ORDER BY Id ,
startDate
DROP TABLE #ranges

Answer 3

DECLARE #MyPeriod TABLE (
ID INT NOT NULL IDENTITY PRIMARY KEY
,StartDate date
,EndDate date
);
INSERT INTO #MyPeriod (StartDate, EndDate)
VALUES ('20120101','20120103')
,('20130928','20131002')
,('20110612','20110615');
SELECT *
FROM #MyPeriod
declare #Start date
declare #end date
set #Start = '2000-01-01'
set #end = '2020-01-01'
;with Dates as (
select #Start as Date
union all
select DATEADD(day,1,Date) from Dates
where Date < #end
)
select MyPeriod.ID, Dates.Date
from Dates
INNER JOIN #MyPeriod MyPeriod
ON Dates.Date BETWEEN MyPeriod.StartDate AND MyPeriod.EndDate
ORDER BY Dates.Date
OPTION(MAXRECURSION 0);

Try this!
CREATE TABLE #TempTable(
ID int,
[Date] date
)
DECLARE #ROWCOUNT INT,#ID INT
DECLARE #Date1 DATE, #Date2 DATE
SET #ROWCOUNT = 1
SET #ID=''
SET #Date1=''
SET #Date1=''
WHILE (#ROWCOUNT <= (SELECT COUNT(*) FROM your_table_name))
BEGIN
SET #ID=(SELECT id FROM your_table_name WHERE ID=#ROWCOUNT)
SET #Date1=(SELECT StartDate FROM your_table_name WHERE ID=#ROWCOUNT)
SET #Date2=(SELECT EndDate FROM your_table_name WHERE ID=#ROWCOUNT)
INSERT INTO #TempTable
SELECT #ID, DATEADD(DAY,number,#Date1) [Date]
FROM master..spt_values
WHERE type = 'P'
AND DATEADD(DAY,number, #Date1) <= #Date2
SET #ROWCOUNT = #ROWCOUNT + 1
END
SELECT * FROM #TempTable
DROP TABLE #TempTable
