Can the below query be rebuilt using setbased rather than iterative logic - sql-server

Question

I am preparing one SSRS report and i have only select access in the table.
I have built the query to get the data.But since i am using table variables, and not getting the desired output in report.
Here is my table structure:
This table stores each job run data with below columns:
jobname
instance_id--ever increasing unique number for each run
starttime
endtime
status
I want to show in my report all above columns and I wrote the query like below.
since I want to show latest run irrespective of success or failure, I need to get max(instance_id) into one table and from that base table I am passing all in loop.
I am getting max instance_id along with row number for looping purposes
create table ##table
(
fqjn varchar(1000),
maxi int,
rownum int
)
create table ##tb
(jobname varchar(max),
[status] varchar(100),
duration int
)
insert into ##table
select jobname,max(instance_id) as maxi,row_number() over (order by jobname desc) as rownum from [dbo].[vw_job_hist]
where grp_data_id in (select grp_Data_id from [dbo].[vw_job_data] where grp_name='pcp')
group by jobname
--now loop through table passing instance_id as parameter
declare #rownum int
select top 1 #rownum=rownum from ##table order by rownum
while #rownum is not null
begin
insert into ##tb
select jh.jobname,"job status"=
case jh.completion_status
when 0 then 'Success'
else 'Failed'
end,
"duration"=datediff(minute,jh.started_time,jh.end_time)
from [dbo].[vw_job_] jh
where jh.instance_id in (select maxi from ##table where rownum=#rownum)
set #rownum=(select top 1 rownum from ##table where rownum>#rownum
order by rownum
end
select * from ##tb
drop table ##tb
drop table ##table
I am not getting the desired output in SSRS ,i know if i create the above query as stored proc,i will get the desired results.but this is third party database and we wont get access.
ask:
Can the above query logic be built in single query with out loop/cursor
I tried using recursive cte ,but no further progress
any help/pointers would be much appreciated

Try this:
;WITH OrderedJobInfo AS (
SELECT jobname, completion_status, started_time, end_time, instance_id
, ROW_NUMBER() OVER (PARTITION BY jobname ORDER BY instance_id DESC) AS rownum
FROM [dbo].[vw_job_hist]
WHERE grp_data_id IN (SELECT grp_Data_id FROM [dbo].[vw_job_data] WHERE grp_name='pcp')
)
SELECT o.jobname, o.instance_id
, [job status] = CASE o.completion_status WHEN 0 THEN 'Success' ELSE 'Failed' END
, [duration] = DATEDIFF(MINUTE, o.started_time, o.end_time)
FROM OrderedJobInfo o
WHERE o.rownum = 1;
