遇到了死锁比较麻烦，但是不要急，我们可以先查看死锁原因，然后杀死死锁的进程如下：
create?? proc p_lockinfo
@kill_lock_spid bit,? --是否杀掉死锁的进程,1 杀掉,0 仅显示
@show_spid_if_nolock bit --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_>',blocked,
? 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',db_name(dbid),
? open_tran,status,net_address
?from master..sysprocesses
?set @count=@@rowcount
end
if @count>0
begin
?create table #t1(id int identity(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 where id=@i
?? insert #t1 exec('dbcc inputbuffer('+@spid)
?? set @i=@i+1
? end
?end
?else
? while @i<=@count
? begin
?? select @s='dbcc inputbuffer('+cast(进程ID as varchar)+')' from #t where id=@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
执行:
查看：exec p_lockinfo 0,1
杀死：exec p_lockinfo 1,1
