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 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
