SqlServer查询和Kill进程死锁的语句

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

kill spid

下面再给大家分享一段关于sqlserver检测死锁;杀死锁和进程;查看锁信息

--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
