SQL Server 数据库死锁状况检查

第一种 可以利用sql 自带的系统存储过程 exec sp_lock

第二中 可以利用手写的存储过程 sp_who_lock  代码如下

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


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
