我要评论下面是我整理的监控sql server数据库，在性能测试过程中是否出现死锁、堵塞的sql语句，还算比较准备，留下来备用。
调用方法：选中相应的数据库，执行exec sp_who_lock
use [master]
go
set ansi_nulls on
go
set quoted_identifier on
go
create procedure [dbo].[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
