Dated Between 2 date variable - sql-server

Question

I have a table with Customers IDs,Name Room Number,Start Date and End date. I want to create a list of dates (daily breakdown) between the start date and end date but want it to look like the tbale i have mocked up in excel in the link below:
i have used
=IF(TEXT(D2,"DD/MM/YYYY")=TEXT(E2,"DD/MM/YYYY"),"Same",IF(F2=DATE(YEAR(D2),MONTH(D2),DAY(D2)),"Start",IF(F2=DATE(YEAR(E2),MONTH(E2),DAY(E2)),"End","Between"))) formula in the Logic ColumN
I have tried to intregrate the following bit of SQL into my query but cant seem to get it to do what i want:
declare #fromdate dateTIME
set #fromdate= '1/1/2017'(Wanted to used Column Startdate)
declare #todate dateTIME = getdate()-1(Wanted used Column Enddate)
;with CTE AS
(SELECT #fromdate AS RESULT
UNION ALL
SELECT RESULT + 1 FROM CTE WHERE RESULT<=#todate
)
SELECT Result,1 as Count FROM CTE OPTION(MAXRECURSION 0)
Any help would be gratefully appreciated.

Answer 1

It is not completely clear what isn't working in your query. If it entails getting the rows per day, the easiest way to go about this is to actually have a date-table ready in your database. You can refer to this date-table in your view. See below an example which I have used in multiple projects.
CREATE PROCEDURE [dbo].[FillDateTable](#StartDate DATE, #EndDate DATE) AS
BEGIN
TRUNCATE TABLE dbo.DateTable;
WITH CTERecursive AS (
SELECT #StartDate AS 'CalendarDate'
UNION ALL
SELECT DATEADD(DAY,1,CalendarDate) AS 'CalendarDate'
FROM CTERecursive
WHERE DATEADD(DAY,1,CalendarDate)<=#EndDate
), TotalCalendar AS (
SELECT CalendarDate
, DAY(CalendarDate) AS 'Day'
, MONTH(CalendarDate) AS 'Month'
, YEAR(CalendarDate) AS 'Year'
, DATEADD(DAY,-DATEPART(WEEKDAY,CalendarDate)+1,CalendarDate) AS 'FirstDayOfWeek'
, DATEADD(DAY,6,DATEADD(DAY,-DATEPART(WEEKDAY,CalendarDate)+1,CalendarDate)) AS 'LastDayOfWeek'
FROM CTERecursive
)
INSERT INTO dbo.DateTable ([CalendarDate], [Day], [Month], [Year], [FirstDayOfWeek], [LastDayOfWeek], [NewWeek])
SELECT *
, NewWeek=CASE WHEN CalendarDate=FirstDayOfWeek THEN 1 ELSE 0 END
FROM TotalCalendar
OPTION (MAXRECURSION 0)
END
Furthermore, it'd be wise to use DATEADD instead of +1 in your CTE.
DECLARE #fromdate DATE
SET #fromdate=CONVERT(DATE,'20170101',112)
DECLARE #todate DATE=GETDATE()-1
;
WITH CTE AS
(SELECT #fromdate AS RESULT
UNION ALL
SELECT DATEADD(DAY,1,RESULT) FROM CTE WHERE RESULT<=#todate
)
SELECT [DateInclusive]=RESULT
,1 as Count FROM CTE OPTION(MAXRECURSION 0)
UPDATE: I'll presume you have a table with the Id, Room, Name, Start- and Enddate readily available. Your query could be structured as follows, yielding an overview similar to your Excel mockup:
DECLARE #Bookings TABLE ([Id] VARCHAR(30), [Room] INT, [Name] VARCHAR(255), [Startdate] DATE, [Enddate] DATE)
INSERT INTO #Bookings VALUES ('V123789',8,'H. Brown','20170201','20170315'),('V555589',1,'J. Frost','20170205','20170420');
WITH CTE AS
(SELECT Id, [Startdate] AS InclusiveDate FROM #Bookings
UNION ALL
SELECT Id, DATEADD(DAY,1,InclusiveDate) FROM CTE WHERE InclusiveDate < (SELECT Enddate FROM #Bookings WHERE Id=CTE.Id)
)
SELECT B.[Id], B.[Room], B.[Name], B.[Startdate], B.[Enddate], CTE.[InclusiveDate]
, CASE WHEN CTE.[InclusiveDate]=B.[Startdate] THEN 'Start'
WHEN CTE.[InclusiveDate]=B.[Enddate] THEN 'End'
WHEN CTE.[InclusiveDate]>B.[Startdate] AND CTE.[InclusiveDate]<B.[Enddate] THEN 'Between' END AS Logic
FROM CTE
JOIN #Bookings B on B.Id=CTE.[Id]
ORDER BY B.[Id], CTE.[InclusiveDate] ASC
OPTION(MAXRECURSION 0)
