Hello all,
I was dealing with some blocked sessions and I wonder if there is a way to know exactly what object is being blocked, I know how to get what spid is blocking the others, but I think it will be really usefull to know the table...

Thanks in advance

Use sp_lock, the spid(s), and objID

Use the following query:

see the output query and the tables in the query.

select req.session_id, ses.login_name,req.blocking_session_id,sqltext.TEXT, req.session_id, req.status, req.command, req.cpu_time, req.total_elapsed_time
from sys.dm_exec_requests req left join sys.dm_exec_sessions ses on req.session_id= ses.session_id
cross apply sys.dm_exec_sql_text(sql_handle) as sqltext

Although, using sys.dm_exec_requests won't show blocking if parallelism is involved.

Another way to do it, and you can use almost the same query, is to look at sys.dm_os_waiting_tasks.
