sql数据库死锁查看sql语句:
复制代码 代码示例:
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
第二部分,sql数据库中杀死锁与进程的方法 >> 数据库死锁怎么办,查看数据库死锁的sql语句
如何去手动的杀死进程和锁?
为了省事,可以重新启动服务。
这里介绍一个存储过程,通过显式的调用,可以杀死进程和锁。
复制代码 代码示例:
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'
第三部分,查看锁信息 >> 查询Sql server数据库死锁的存储过程
如何查看系统中所有锁的详细信息?在企业管理管理器中,可以看到一些进程和锁的信息。
另外一种方法。
复制代码 代码示例:
--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
其实就是二个sql语句:
复制代码 代码示例:
select 0 spid ,'受阻于' 受阻于,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,'受阻于',blocked from sysprocesses where blocked>0
--DBCC INPUTBUFFER (76) --查看進程ID執行內容
select Pid=a.req_spid,Db=db_name(rsc_dbid),Type=case rsc_type when 1 then 'NULL'
when 2 then 'DB' when 3 then 'File' when 4 then 'Indx' when 5 then 'Tabl' when 6 then 'Page'
when 7 then 'Key' when 8 then 'ExDiskArea' when 9 then 'RowID' when 10 then 'App' end,
rsc_indid,Objid=rsc_objid,ObjName=(select name from ['dbname']..sysobjects where id=a.rsc_objid)
from master..syslockinfo a --查看進程較多信息 [dbname 替換成你要監控的db]
当得到相关信息后,即可以kill ID杀掉死锁进程了。
