如何知道是哪个进程造成死锁?如何把这个进程杀掉?

2020-11-22 来源:伴沃教育
MSSQL(查找死锁):

use master go

declare @spid int,@bl int DECLARE s_cur CURSOR FOR 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 OPEN s_cur

FETCH NEXT FROM s_cur INTO @spid,@bl WHILE @@FETCH_STATUS = 0 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 )

FETCH NEXT FROM s_cur INTO @spid,@bl end

CLOSE s_cur

DEALLOCATE s_cur

create proc sp_lockinfo

@kill_lock_spid bit=1, --是否杀掉阻塞的进程,1 杀掉, 0 仅显示
