SQL Server死锁使我们经常遇到的问题，接下来的SQL server内容就为您介绍如何查询SQL Server死锁，希望对您学习SQL Server死锁方面能有所帮助。
SQL Server死锁的查询方法：
exec master.dbo.p_lockinfo 0,0 ---显示死锁的进程,不显示正常的进程 exec master.dbo.p_lockinfo 1,0 ---杀死死锁的进程,不显示正常的进程
SQL Server死锁的解除方法：
Create proc p_lockinfo @kill_lock_spid bit=1, --是否杀掉死锁的进程,1 杀掉, 0 仅显示 @show_spid_if_nolock bit=1 --假如没有死锁的进程,是否显示正常进程信息,1 显示,0 不显示 as declare @count int,@s nvarchar(1000),@i int select id=identity(int,1,1),标志, 进程ID=spid,线程ID=kpid,块进程ID=blocked,数据库ID=dbid, 数据库名=db_name(dbid),用户ID=uid,用户名=loginame,累计CPU时间=cpu, 登陆时间=login_time,打开事务数=open_tran, 进程状态=status, 工作站名=hostname,应用程序名=program_name,工作站进程ID=hostprocess, 域名=nt_domain,网卡地址=net_address into #t from( select 标志='死锁的进程', spid,kpid,a.blocked,dbid,uid,loginame,cpu,login_time,open_tran, status,hostname,program_name,hostprocess,nt_domain,net_address, s1=a.spid,s2=0 from master..sysprocesses a join ( select blocked from master..sysprocesses group by blocked )b on a.spid=b.blocked where a.blocked=0 union all select '|_牺牲品_>', spid,kpid,blocked,dbid,uid,loginame,cpu,login_time,open_tran, status,hostname,program_name,hostprocess,nt_domain,net_address, s1=blocked,s2=1 from master..sysprocesses a where blocked<>0 )a order by s1,s2 select @count=@@rowcount,@i=1 if @count=0 and @show_spid_if_nolock=1 begin insert #t select 标志='正常的进程', spid,kpid,blocked,dbid,db_name(dbid),uid,loginame,cpu,login_time, open_tran,status,hostname,program_name,hostprocess,nt_domain,net_address from master..sysprocesses set @count=@@rowcount end if @count>0 begin create table #t1(id int identity(1,1),a nvarchar(30),b Int,EventInfo nvarchar(255)) if @kill_lock_spid=1 begin declare @spid varchar(10),@标志 varchar(10) while @i<=@count begin select @spid=进程ID,@标志=标志 from #t whereid=@i insert #t1 exec('dbcc inputbuffer('+@spid+')') if @标志='死锁的进程' exec('kill'+@spid) set @i=@i+1 end end else while @i<=@count begin select @s='dbcc inputbuffer('+cast(进程ID as varchar)+')' from #t whereid=@i insert #t1 exec(@s) set @i=@i+1 end select a.*,进程的SQL语句=b.EventInfo from #t a join #t1 b on a.id=b.id end
