sqlserver 2008 R2 进程查看

sqlserver 2008 R2 在哪里看当前活动和锁？还有在哪儿看数据库进程列表？

SQL code

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[sp_who_lock]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)  drop procedure [dbo].[sp_who_lock]  GO  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 @spidspid = spid,@blbl = 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

--当然我们也可以结合其他的动态管理视图，直接查出某个数据库上面的锁是在哪些表格，以及在哪些索引上面。例如（图9-3）：
use AdventureWorks
go

on sys.dm_tran_locks.resource_associated_entity_id = p.hobt_id
WHERE resource_database_id = db_id('AdventureWorks')
order by request_session_id, resource_type, resource_associated_entity_id

如何判断数据库的死锁

begin

            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'

CLOSE s_cur
DEALLOCATE s_cur
