   select '现在没有阻塞和死锁信息' as message

   select @spid = spid,@bl = bl

   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 
  -- 循环指针下移
  set @intCounter = @intCounter + 1
  end
  drop table #tmp_lock_who
  return 0
  end

执行Exec sp_who_lock显示结果
