SQL Server死锁使我们经常遇到的问题,下面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 --如果没有死锁的进程,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
