遇到了死鎖比較麻煩，但是不要急，我們可以先查看死鎖原因，然后殺死死鎖的進(jìn)程如下：

create?? proc p_lockinfo
@kill_lock_spid bit,? --是否殺掉死鎖的進(jìn)程,1 殺掉, 0 僅顯示
@show_spid_if_nolock bit --如果沒有死鎖的進(jìn)程,是否顯示正常進(jìn)程信息,1 顯示,0 不顯示
as
declare @count int,@s nvarchar(1000),@i int
select id=identity(int,1,1),標(biāo)志,
?進(jìn)程ID=spid,線程ID=kpid,塊進(jìn)程ID=blocked,數(shù)據(jù)庫ID=dbid,
?數(shù)據(jù)庫名=db_name(dbid),用戶ID=uid,用戶名=loginame,累計CPU時間=cpu,
?登陸時間=login_time,打開事務(wù)數(shù)=open_tran, 進(jìn)程狀態(tài)=status,
?工作站名=hostname,應(yīng)用程序名=program_name,工作站進(jìn)程ID=hostprocess,
?域名=nt_domain,網(wǎng)卡地址=net_address
into #t from(
?select 標(biāo)志='死鎖的進(jìn)程',
? spid,kpid,a.blocked,dbid,uid,loginame,cpu,login_time,open_tran,
? status,hostname,program_name,hostprocess,nt_domain,net_address,

?from master..sysprocesses a join (

? 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 標(biāo)志='正常的進(jìn)程',
? spid,kpid,blocked,dbid,db_name(dbid),uid,loginame,cpu,login_time,

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),@標(biāo)志 varchar(10)
? while @i<=@count
? begin
?? select @spid=進(jìn)程ID,@標(biāo)志=標(biāo)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(進(jìn)程ID as varchar)+')' from #t where id=@i
?? insert #t1 exec(@s)
?? set @i=@i+1
? end
?select a.*,進(jìn)程的SQL語句=b.EventInfo
?from #t a join #t1 b on a.id=b.id
end

執(zhí)行:

查看：exec p_lockinfo 0,1
殺死：exec p_lockinfo 1,1
