SqlServer查询和Kill进程死锁的语句_Sql Server

查询死锁进程语句

									select

									request_session_id spid, 

									OBJECT_NAME(resource_associated_entity_id) tableName 

									from

									sys.dm_tran_locks 

									where

									resource_type='OBJECT'

杀死死锁进程语句

1	`kill spid`

									--检测死锁

									--如果发生死锁了，我们怎么去检测具体发生死锁的是哪条SQL语句或存储过程？

									--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'

									--查看锁信息

									--如何查看系统中所有锁的详细信息？在企业管理管理器中，我们可以看到一些进程和锁的信息，这里介绍另外一种方法。

									--查看锁信息

									create table #t(req_spid int,obj_name sysname)

									declare @s nvarchar(4000)

									 ,@rid int,@dbname sysname,@id int,@objname sysname

									declare tb cursor for

									 select distinct req_spid,dbname=db_name(rsc_dbid),rsc_objid

									 from master..syslockinfo where rsc_type in(4,5)

									open tb

									fetch next from tb into @rid,@dbname,@id

									while @@fetch_status=0

									begin

									 set @s='select @objname=name from ['+@dbname+']..sysobjects where id=@id'

									 exec sp_executesql @s,N'@objname sysname out,@id int',@objname out,@id

									 insert into #t values(@rid,@objname)

									 fetch next from tb into @rid,@dbname,@id

									end

									close tb

									deallocate tb

									select 进程id=a.req_spid

									 ,数据库=db_name(rsc_dbid)

									 ,类型=case rsc_type when 1 then 'NULL 资源（未使用）'

									  when 2 then '数据库'

									  when 3 then '文件'

									  when 4 then '索引'

									  when 5 then '表'

									  when 6 then '页'

									  when 7 then '键'

									  when 8 then '扩展盘区'

									  when 9 then 'RID（行 ID)'

									  when 10 then '应用程序'

									 end

									 ,对象id=rsc_objid

									 ,对象名=b.obj_name

									 ,rsc_indid

									 from master..syslockinfo a left join #t b on a.req_spid=b.req_spid

									go

									drop table #t
