是否堵塞
SELECT spid,blocked,waittime,waittype,waitresource,p.dbid,cpu,physical_io,memusage,open_tran
,status,login_time,last_batch,hostname,program_name,hostprocess,loginame,cmd,text

检查锁表
select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName
from sys.dm_tran_locks t where resource_type='OBJECT' order by spid asc;
查询导致死锁的sql语句
dbcc inputbuffer(spid);
解锁
declare @spid int
Set @spid = 123--锁表进程
declare @sql varchar(1000)
set @sql='kill '+cast(@spid as varchar)
exec(@sql)
杀掉进程
kill spid
