SQL Server数据库阻塞，死锁查询

sql 查询卡顿数据库

SELECT SPID=p.spid,
       DBName = convert(CHAR(20),d.name),
       ProgramName = program_name,
       LoginName = convert(CHAR(20),l.name),
       HostName = convert(CHAR(20),hostname),
       Status = p.status,
       BlockedBy = p.blocked,
       LoginTime = login_time,
       QUERY = CAST(TEXT AS VARCHAR(MAX))
FROM   MASTER.dbo.sysprocesses p
       INNER JOIN MASTER.dbo.sysdatabases d
         ON p.dbid = d.dbid
       INNER JOIN MASTER.dbo.syslogins l
         ON p.sid = l.sid
       CROSS APPLY sys.dm_exec_sql_text(sql_handle)
WHERE  p.blocked = 0
       AND EXISTS (SELECT 1
                   FROM   MASTER..sysprocesses p1
                   WHERE  p1.blocked = p.spid)

存储过程查询具体的死锁，阻塞中的sql语句

新建存储过程

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

begin

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

GO

后续可直接执行存储过程查看

exec sp_who_lock

结束阻塞的进程

kill 进程号
