第4章需求一：GMV成交总额
4.1 ADS层
4.1.2建表语句

hive (gmall)>
drop table if exists ads_gmv_sum_day;
create external table ads_gmv_sum_day(
dt string COMMENT ‘统计日期’,
gmv_count bigint COMMENT ‘当日gmv订单个数’,
gmv_amount decimal(16,2) COMMENT ‘当日gmv订单总金额’,
gmv_payment decimal(16,2) COMMENT ‘当日支付金额’
) COMMENT ‘GMV’
row format delimited fields terminated by ‘\t’
location ‘/warehouse/gmall/ads/ads_gmv_sum_day/’
;
4.1.3数据导入

1）数据导入
hive (gmall)>
insert into table ads_gmv_sum_day
select
‘2019-02-10’ dt,
sum(order_count)gmv_count,
sum(order_amount) gmv_amount,
sum(payment_amount) payment_amount
from dws_user_action
where dt =‘2019-02-10’
group by dt
;
2）查询导入数据
hive (gmall)> select * from ads_gmv_sum_day;

4.1.4数据导入脚本

1）在/home/atguigu/bin目录下创建脚本ads_db_gmv.sh
[atguigu@hadoop102 bin]$ vim ads_db_gmv.sh
在脚本中填写如下内容
#!/bin/bash

定义变量方便修改

APP=gmall
hive=/opt/module/hive/bin/hive

如果是输入的日期按照取输入日期；如果没输入日期取当前时间的前一天

if [ -n “$1” ] ;then
do_date=$1
else
do_date=date -d "-1 day" +%F
fi

sql="
insert into table "$APP".ad{s}_{g}m{v}_{s}u{m}_{d}ayselec{t}^{\prime }$do_date’ dt,
sum(order_count) gmv_count,
sum(order_amount) gmv_amount,
sum(payment_amount) payment_amount
from "$APP".dw{s}_{u}se{r}_{a}ctionwheredt{=}^{\prime }$do_date’
group by dt;
"

$hive-e"$sql"
2）增加脚本执行权限
[atguigu@hadoop102 bin]$ chmod 777 ads_db_gmv.sh
3）执行脚本导入数据
[atguigu@hadoop102 bin]$ads_db_gmv.sh 2019-02-11
4）查看导入数据
hive (gmall)>
select * from ads_gmv_sum_day where dt=‘2019-02-11’ limit 2;
