set transaction isolation level read uncommitted
select es.session_id

,est.text

,cn.last_write
,es.program_name
from sys.dm_exec_sessions es
inner join sys.dm_tran_session_transactions st --系統裏還存在的事務
on es.session_id = st.session_id
inner join sys.dm_exec_connections cn on es.session_id = cn.session_id
cross apply sys.dm_exec_sql_text(cn.most_recent_sql_handle) est
left outer join sys.dm_exec_requests er on st.session_id = er.session_id
and er.session_id is null

然後直接Kill ‘session_id’就可以回滾這個事務了
