--转贴:

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
