I have the following type of data
CREATE TABLE #tmp
(
Room [NVARCHAR](50) NOT NULL,
iking INT,
iqueen INT,
isingle INT,
idouble INT
)
INSERT INTO #tmp
VALUES ('Marriot', 0, 1, 2, 1),
('Hilton', 1, 2, 0, 1)
I tried Cross Apply and case statements
I add data into temp table and wrote 4 cross apply functions for each column
King
SELECT tk.Room, tk.iking, Type = CONCAT('BED', t.n)
INTO #tempking1
FROM #tmp tk
CROSS APPLY
(SELECT TOP (tk.iking)
n = ROW_NUMBER() OVER (ORDER BY o.object_id)
FROM sys.objects o) t
ORDER BY tk.Room;
--select * from #tempking1
Queen
SELECT
tq.Room, tq.iQueen,
Type = CASE WHEN ROOM in (SELECT Distinct ROOM FROM #tempking1)
THEN CONCAT('BED', t.n + 1)
ELSE CONCAT('BED', t.n)
END
INTO #tempQueen1
FROM #tmp tq
CROSS APPLY
(SELECT TOP (tq.iQueen)
n = ROW_NUMBER() OVER (ORDER BY o.object_id)
FROM sys.objects o) t
ORDER BY tq.Room;
--select * from #tempqueen1
Single
SELECT
tq.Room, tq.isingle,
Type = CASE WHEN ROOM IN (SELECT Distinct ROOM FROM #tempking1)
THEN CONCAT('BED', t.n + 1)
WHEN ROOM IN (SELECT Distinct ROOM FROM #tempqueen1)
THEN CONCAT('BED', t.n + 1)
ElSE CONCAT('BED', t.n)
END
INTO #tempsingle1
FROM #tmp tq
CROSS APPLY
(SELECT TOP (tq.isingle)
n = ROW_NUMBER() OVER (ORDER BY o.object_id)
FROM sys.objects o) t
ORDER BY tq.Room;
--select * from #tempsingle1
Double
SELECT
tq.Room, tq.isingle,
Type = CASE WHEN ROOM IN (SELECT Distinct ROOM FROM #tempking1)
THEN CONCAT('BED', t.n + 1)
WHEN ROOM IN (SELECT Distinct ROOM FROM #tempqueen1)
THEN CONCAT('BED', t.n + 1)
WHEN ROOM IN (SELECT Distinct ROOM FROM #tempsingle1)
THEN CONCAT('BED', t.n + 1)
ELSE CONCAT('BED', t.n)
END
INTO #tempdouble1
FROM #tmp tq
CROSS APPLY
(SELECT TOP (tq.isingle)
n = ROW_NUMBER() OVER (ORDER BY o.object_id)
FROM sys.objects o) t
ORDER BY tq.Room;
--select * from #tempDouble1
SELECT Room, Type, 'King' AS Descp FROM #tempKing1
UNION ALL
SELECT Room, Type, 'Queeen' AS Descp FROM #tempQueen1
UNION ALL
SELECT Room, Type, 'Single' AS Descp FROM #tempsingle1
UNION ALL
SELECT Room, Type, 'Double' AS Descp FROM #tempDouble1
but I got
My excepted output is
Could you please help me

You can use UNPIVOT operator to fix your solution. Try this script:
drop TABLE #tmp
go
drop TABLE #Hotel
go
CREATE TABLE #tmp
(
Room nvarchar(30) NOT NULL
,iking int
,iqueen int
,isingle int
,idouble int
)
CREATE TABLE #Hotel
(
Room NVARCHAR(30)
,RoomType NVARCHAR(30)
,Total INT
)
Insert into #tmp Values ('Marriot', 0,1,2,1),('Hilton', 1,2,0,1)
INSERT INTO #Hotel
SELECT Room, RoomType, Total
FROM
(SELECT Room,iking,iqueen,isingle,idouble
FROM #tmp) p
UNPIVOT
(Total FOR RoomType IN
(iking,iqueen,isingle,idouble)
)AS unpvt
SELECT Room
,RoomType
--,'Bed'+CAST(Number AS VARCHAR) AS [Desc]
,'Bed'+CAST(ROW_NUMBER() OVER(PARTITION BY Room ORDER BY RoomType,Number) AS VARCHAR) AS [Desc]
,'Bed'+CAST(Total AS varchar) [Desc2]
FROM #Hotel
INNER JOIN master.dbo.spt_values N ON Total>=N.Number AND N.type='P' AND number<>0
