How to find which Program or User executed Query using Query Store in SQL Server 2016+

问题

After enabling query store, how to find who executed the query. For example, in case of trace collection, there is TRC file which will get the hostname and program details for query and in case of Extended-Events, we have XEL file which will get the hostname and program details. We tried code

SELECT des.program_name,
des.host_name,
*
FROM sys.query_store_query_text qt -- Query Text
JOIN sys.query_store_query q ON qt.query_text_id = q.query_id -- Query Data
JOIN sys.query_store_plan qp on qp.query_id = q.query_id --  Query Plan
join sys.dm_exec_requests der on der.query_hash = q.query_hash -- Get session id for query
join sys.dm_exec_sessions des on des.session_id = der.session_id -- Session Info
order by q.last_execution_time desc

Below DMV return null values for Query Hash (query_hash) hence no data for above query

select * from sys.dm_exec_requests der
select * from sys.dm_exec_sessions des
