David, Thank you for Sharing
I saw the use of master.dbo.fn_varbintohexstr
I like your approach better, even if Microsoft doesn't support it anymore (I still see it at SQL 2014)
Another Article Replacement for using fn_varbintohexstr or the use of the CONVERT

Before, I was using this view to get details from TempDB
SELECT *
FROM (
SELECT TOP 100 PERCENT
spu.session_id
, db_name(r.database_id) dbname
, s.host_name host
, s.login_name loginname
, s.program_name [program_name]
, ISNULL(j.name, 'N/A') AS [Job Name]
, ( CASE WHEN ( CHARINDEX('SQLAgent', s.program_name) > 0 ) THEN REPLACE( SUBSTRING( s.program_name, 67, 10 ), ')', '')
ELSE 'N/A' END ) step
, r.start_time
, r.wait_time
, r.cpu_time
, r.logical_reads
, r.reads
, r.writes
, LTRIM( t.text ) text
FROM sys.dm_db_session_space_usage spu
JOIN sys.dm_exec_sessions s ON s.session_id = spu.session_id
JOIN sys.dm_exec_requests r ON s.session_id = r.session_id
INNER JOIN msdb.dbo.sysjobs j ON master.dbo.fn_varbintohexstr(CONVERT(varbinary(16), job_id)) = SUBSTRING(REPLACE(PROGRAM_NAME, 'SQLAgent - TSQL JobStep (Job ', ''), 1, 34)
CROSS APPLY sys.dm_exec_sql_text(sql_handle) t,
( SELECT su.session_id, su.request_id
, SUM( su.internal_objects_alloc_page_count + su.user_objects_alloc_page_count) Task_Alloc
, SUM( su.internal_objects_dealloc_page_count + su.user_objects_dealloc_page_count) Task_Dealloc
FROM sys.dm_db_task_space_usage AS su
GROUP BY session_id, request_id ) AS su
WHERE r.status = 'running'
AND su.session_id = r.session_id
AND ( su.request_id = r.request_id )
AND ( s.session_id = su.session_id )
AND s.login_name NOT IN ('CORP\lmorales','corp\eRuhnke') -- Remove SA users
AND s.session_id <> ( SELECT @@SPID ) -- Eliminates current user session from results
AND su.session_id > 50 -- Sessions 50 and below are system sessions and should not be killed
AND s.program_name NOT IN ('SQL diagnostic manager Collection Service','SQL diagnostic manager Management Service')
) cia
There's still much to learn and improve.
Thank you.
