msyql实现oracle分组排序

oracle：

select 
     t.vul_id,
     t.deal_status,
     t.create_time,
     row_number() over(partition by t.vul_id order by t.create_time desc) lastnum,
     row_number() over(partition by t.vul_id,t.deal_status order by t.create_time asc) finishnum
from VUL_TASK_DEAL t where t.deal_source = 1
order by t.deal_id

mysql:
