查看死锁的SQL语句

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 

 

exec sp_who2 

运行sp_who2 ,看blk by 栏， 如果这栏不是空白， 有一个数字， 这就是造成阻塞（blocking）的线程id. 然后运行DBCC Inputbuffer(线程id), 你就可以看见这个线程在干什么。
