hive统计店铺每个月的营业额以及到当目前的历史累计额

--------数据
名称，月份，资金
a,01,150
a,01,200
b,01,1000
b,01,800
c,01,250
c,01,220
b,01,6000
a,02,2000
a,02,3000
b,02,1000
b,02,1500
c,02,350
c,02,280
a,03,350
a,03,250
----建表
create table t_store(
name string,
months int,
money int 
)
row format delimited fields terminated by ","



1.将数据加载进去
load data local inpath "/home/hadoop/store.txt" into table t_storre

2 需求 编写Hive的HQL语句求出每个店铺的当月销售额和累计到当月的总销售额
	店铺，当月累计，累计到当前的销售
-----------

1.求出每个店铺的当月累计消费额


	创建一个临时表
create table tmp_store1 as 
select name,months,sum(money) as money from t_store group by name,months;

select * from tmp_store1;

名称 月份 累计收益
a 01 5000
a 02 6000
b 01 400
b 02 5000

对临时表tmp_store1表中的数据进行自然连接
create table tmp_store2 as

select a.name aname,a.months amonths,a.money amoney ,b.name bname,b.months bmonths,b.money bmoney from tmp_store1 a join tmp_store1 b on a.name=b,name order by anaem,amonths;

select * from tmp_store2;

a 01 5000 a 01 5000
a 01 5000 a 02 6000
a 02 6000 a 01 5000
a 02 6000 a 02 6000
b 01 400 b 02 5000
b 01 400 b 01 400 
b 02 5000 b 01 400
b 02 5000 b 02 5000

比较统计

select aname,amonths,amoney
sum (bmoney) as total from tep_store2
where amonths>=bmonths
group by aname,amonths,amoney
