sqlserver中如何查看被死锁的表和进程

--查看被锁表：
select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName
from sys.dm_tran_locks where resource_type='OBJECT'
order by tablename

--解锁：
declare @spid int
Set @spid = 71 --锁表进程
declare @sql varchar(1000)
set @sql='kill '+cast(@spid as varchar)
exec(@sql)

--查询出死锁的SPID
select blocked
from (select * from sysprocesses where blocked>0 ) a
where not exists(select * from (select * from sysprocesses where blocked>0 ) b
where a.blocked=spid)

--查死锁进程
select dbid,* from sys.sysprocesses
where 1=1
--and spid >50
and blocked <> 0

--查看死锁的语句
