SQL query unknown rows into columns - sql

Question

I asked this question and it was marked as a duplicate of How to pivot unknown number of columns & no aggregate in SQL Server?, but that answer doesn't help me.
I have a table of data that looks like this, with an unknown number of rows and values.
RecID Name Value
1 Color Red
2 Size Small
3 Weight 20lbs
4 Shape Square
I need a query that will return the data like this, building out a column for each row. I cannot hard code anything except the column headers 'Name' and 'Value'.
Color Size Weight Shape
Red Small 20lbs Square
Here is what I have so far that is partly working:
INSERT INTO #Table VALUES
(1,'Color' ,'Red'),
(2,'Size' ,'Small'),
(3,'Weight','20lbs'),
(4,'Shape' ,'Square')
;with mycte
as
(
SELECT rn,cols,val
FROM (SELECT row_number() over(order by Name) rn, Name, Value
FROM #Table) AS src1
UNPIVOT (val FOR cols
IN ( [Name], [Value])) AS unpvt
)
SELECT *
FROM (SELECT rn,cols,val
FROM mycte) AS src2 PIVOT
( Max(val) FOR rn IN ([1], [2], [3])) AS pvt
Which returns:
cols 1 2 3
Name Color Shape Size
Value Red Square Small
Two problems with this that I can't seem to resolve.
I don't need the column headers and the first column that has cols, Name, Value in it.
Can't figure out how to have it build a column for each row without specifying the [x] identifiers.
Any guidance would be great I've been stuck on this a while now.

Answer 1

declare #collist nvarchar(max)
SET #collist = stuff((select distinct ',' + QUOTENAME(name)
FROM #t -- your table here
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
declare #q nvarchar(max)
set #q = '
select *
from (
select rn, name, Value
from (
select *, row_number() over (partition by name order by RecID desc) as rn
from #t -- your table here
) as x
) as source
pivot (
max(Value)
for name in (' + #collist + ')
) as pvt
'
exec (#q)

Answer 2

Until now, I have reached to following code, hope it helps you,
Current outpu comes as
Color Shape Size Weight
Red NULL NULL NULL
NULL NULL Small NULL
NULL NULL NULL 20lbs
NULL Square NULL NULL
Create table DyTable
(
tid int,
Name varchar(20),
Value varchar(20)
)
INSERT INTO DyTable VALUES
(1,'Color' ,'Red'),
(2,'Size' ,'Small'),
(3,'Weight','20lbs'),
(4,'Shape' ,'Square')
DECLARE #Cols NVARCHAR(MAX);
DECLARE #Cols1 NVARCHAR(MAX);
SELECT #Cols = STUFF((
SELECT DISTINCT ', ' + QUOTENAME(Name)
FROM DyTable
FOR XML PATH(''), TYPE).value('.','NVARCHAR(MAX)'),1,2,'')
,#Cols1 = STUFF((
SELECT DISTINCT ', max(' + QUOTENAME(Name) + ') as ' + Name
FROM DyTable
FOR XML PATH(''), TYPE).value('.','NVARCHAR(MAX)'),1,2,'')
DECLARE #Sql NVARCHAR(MAX)
Select #Cols
SET #Sql = 'Select '+ #Cols1 +'
from (SELECT ' + #Cols + '
FROM DyTable t
PIVOT (MAX(Value)
FOR Name
IN (' + #Cols + ')
)P)a'
EXECUTE sp_executesql #Sql
