select @intCountProperties = Count(*),@intCounter = 1

if @intCountProperties=0
select N现在没有阻塞和死锁信息 as message
— 循环开始
while @intCounter <= @intCountProperties
begin
— 取第一条记录
select @spid = spid,@bl = bl
from #tmp_lock_who where Id = @intCounter
begin
 if @spid =0
            select N引起数据库死锁的是: + CAST(@bl AS VARCHAR(10)) + N进程号,其执行的SQL语法如下
 else
            select N进程号SPID：+ CAST(@spid AS VARCHAR(10))+ N被 + N进程号SPID：+ CAST(@bl AS VARCHAR(10)) +N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
