sqlserver 2005 查看和kill死鎖

由于最近数据库量和查询较为复杂,导致数据库死锁,但又不知道如何检查哪句死住了,于是网到以下方法
这时我们可以使用以下存储过程来检测,就可以查出引起死锁的进程和SQL语句。SQL Server自带的系统存储过程sp_who和sp_lock也可以用来查找阻塞和死锁, 但没有这里介绍的方法好用。
use master
go
create procedure sp_who_lock
as
begin
declare @spid int,@bl int,
@intTransactionCountOnEntry int,
@intRowcount int,
@intCountProperties int,
@intCounter int
create table #tmp_lock_who
(
id int identity(1,1),
spid smallint,
bl smallint)
IF @@ERROR<>0 RETURN @@ERROR
insert into #tmp_lock_who(spid,bl) select 0 ,blocked
from (select * from sysprocesses where blocked>0 )
a
where not exists(select * from (select * from sysprocesses where blocked>0 )
b
where a.blocked=spid)
union select spid,blocked from sysprocesses where blocked>0
IF @@ERROR<>0 RETURN @@ERROR
-- 找到临时表的记录数
select @intCountProperties = Count(*),@intCounter = 1
from #tmp_lock_who
IF @@ERROR<>0 RETURN @@ERROR
if @intCountProperties=0
select '现在没有阻塞和死锁信息' as message
-- 循环开始
while @intCounter <= @intCountProperties
begin
-- 取第一条记录
select @spid = spid,@bl = bl
from #tmp_lock_who where Id = @intCounter
begin
if @spid =0
select '引起数据库死锁的是: '+ CAST(@bl AS VARCHAR(10)) + '进程号,其执行的SQL语法如下'
else
select '进程号SPID:'+ CAST(@spid AS VARCHAR(10))+ '被' + '进程号SPID:'+ CAST(@bl AS VARCHAR(10)) +'阻塞,其当前进程执行的SQL语法如下'
DBCC INPUTBUFFER (@bl )
end
-- 循环指针下移
set @intCounter = @intCounter + 1
end
drop table #tmp_lock_who
return 0
end
杀死锁和进程
如何去手动的杀死进程和锁?最简单的办法,重新启动服务。但是这里要介绍一个存储过程,通过显式的调用,可以杀死进程和锁。
use master
go
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[p_killspid]') and OBJECTPROPERTY(id,
N'IsProcedure') = 1)
drop procedure [dbo].[p_killspid]
GO
create proc p_killspid
@dbname varchar(200) --要关闭进程的数据库名
as
declare @sql nvarchar(500)
declare @spid nvarchar(20)
declare #tb cursor for
select spid=cast(spid as varchar(20)) from master..sysprocesses where dbid=db_id(@dbname)
open #tb
fetch next from #tb into @spid
while @@fetch_status=0
begin
exec('kill '+@spid)
fetch next from #tb into @spid
end
close #tb
deallocate #tb
go
--用法
exec p_killspid 'newdbpy'
