hive查询

查询语句可以直接使用非分析函数的变量的别名

select t1.*
from
(
select account_id, sum(recharge_money) recharge_money_total
from dw.dw_app
where dt='2016-11-21'
and app_id=''
and msgtype = 'role.recharge'
group by account_id
order by recharge_money_total desc
limit
) t1
limit ;

分析函数必须套一个查询，不能直接用rn <=5

select t1.*
from
(
select account_id, sum(recharge_money) recharge_money_total,
  row_number() over (order by sum(recharge_money) desc) as rn
from dw.dw_app
where
dt='2016-11-21'
and app_id=''
and msgtype = 'role.recharge'
group by account_id
) t1
where t1.rn <=
