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 mastergocreate procedure sp_who_lockasbegindeclare @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 ) awhere not exists(select * from (select * from sysprocesses where blocked>0 ) bwhere 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 @@ERRORif @intCountProperties=0 select "现在没有阻塞和死锁信息" as message-- 循环开始while @intCounter <= @intCountPropertiesbegin-- 取第一条记录 select @spid = spid,@bl = bl from #tmp_lock_who where Id = @intCounterbegin if @spid =0select "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 + 1enddrop table #tmp_lock_whoreturn 0end--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 mastergoif exists (select * from dbo.sysobjects where id = object_id(N"[dbo].[p_killspid]") and OBJECTPROPERTY(id, N"IsProcedure") = 1)drop procedure [dbo].[p_killspid]GOcreate proc p_killspid@dbname varchar(200) --要关闭进程的数据库名asdeclare @sql nvarchar(500)declare @spid nvarchar(20) declare #tb cursor forselect 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 endclose #tb deallocate #tbgo--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 sysnamedeclare tb cursor forselect distinct req_spid,dbname=db_name(rsc_dbid),rsc_objid from master..syslockinfo where rsc_type in(4,5)open tbfetch next from tb into @rid,@dbname,@idwhile @@fetch_status=0begin 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,@idendclose tbdeallocate tbselect 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_spidgodrop table #t
