資料庫死鎖查詢

檢視資料庫鎖：

use [master]

end

關閉資料庫鎖：

重啟sql服務即可，亦可

use mastergo 
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) --要關閉程序的資料庫名
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 #tbgo 
--用法 
exec p_killspid 'newdbpy'

另外，可以檢視鎖資訊：

–檢視鎖資訊

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 endclose tb deallocate tb select 程序id=a.req_spid ,資料庫=db_name(rsc_dbid) ,型別=case rsc_type when 1 then 'null 資源（未使用）' when 2 then '資料庫' when 3 then '檔案' when 4 then '索引' when 5 then '表' when 6 then '頁' when 7 then '鍵' when 8 then '擴充套件盤區' when 9 then 'rid（行 id)' when 10 then '應用程式' end,物件id=rsc_objid ,物件名=b.obj_name ,rsc_indid from master..syslockinfo a left join #t b on a.req_spid=b.req_spid go
