如何处理Sql server中的死锁问题
1、用数据库sa用户登录。
2、创建民激查询死锁的存储过程。
--找引发锁的sql
create procedure pro_killsid
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<薪囊>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
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
while @intCounter <= @intCountProperties
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
set @intCounter = @intCounter + 1
end
drop table #tmp_lock_who
return 0
end
3、执行创建的存储过程。
用master执行存储过程:execute pro_killsid
4、Kill掉死锁的进程SID号。
5、再用master执行存储过程:execute pro_killsid
检测是否还有死锁。三阅欠
