how to display data with dynamic columns -SQL - sql

Question

I have a dynamic pivot query that has dynamic columns column1, column 2... column
My query works fine. I can dump it into temp table ... But I wanted a view. I can't because of the changing number of columns. What do I do? It took long time to put this query together as I am not sql expert.
I would like to have a view of the result so I can link it to Access for the teams. I also have to create more queries in Access based on this link so the link can not disconnect. Any help will be appreciated
Below is my query.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SELECT #cols = STUFF((SELECT ','
+ QUOTENAME(case
when d.col = 'OriginalDx' then col+cast(seq as varchar(10))
else 'OriginalDx'+cast(seq as varchar(10))+'_'+col end)
from
(
select row_number() over(partition by [HCCCodingBASEID]
order by [HCCCodingBASEID]) seq
from [IDEAApplication].[HCCCoding].[OriginalDiagnosis]
) t
cross apply
(
select 'OriginalDx', 1
) d (col, so)
group by col, so, seq
order by seq, so
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT [HCCCodingBASEID] AS ORIGINALDX_ID, ' + #cols + '
