需求十一：用户行为漏斗分析
需求十二：品牌复购率
需求十三：ADS层品牌复购率报表分析
需求十四：求每个等级的用户对应的复购率前十的商品排行

需求一：用户活跃主题

DWS层--（用户行为宽表层）目标：统计当日、当周、当月活动的每个设备明细

1 每日活跃设备明细 dwd_start_log--->dws_uv_detail_day

--把相同的字段collect_set到一个数组, 按mid_id分组(便于后边统计)

collect_set将某字段的值进行去重汇总，产生array类型字段。如: concat_ws('|', collect_set(user_id)) user_id,

建分区表dws_uv_detail_day：partitioned by ('dt' string)

drop table if exists dws_uv_detail_day;
create table dws_uv_detail_day( 
    `mid_id` string COMMENT '设备唯一标识',
    `user_id` string COMMENT '用户标识', 
    `version_code` string COMMENT '程序版本号', 
    `version_name` string COMMENT '程序版本名', 
`lang` string COMMENT '系统语言', 
`source` string COMMENT '渠道号', 
`os` string COMMENT '安卓系统版本', 
`area` string COMMENT '区域', 
`model` string COMMENT '手机型号', 
`brand` string COMMENT '手机品牌', 
`sdk_version` string COMMENT 'sdkVersion', 
`gmail` string COMMENT 'gmail', 
`height_width` string COMMENT '屏幕宽高',
`app_time` string COMMENT '客户端日志产生时的时间',
`network` string COMMENT '网络模式',
`lng` string COMMENT '经度',
`lat` string COMMENT '纬度'
) COMMENT '活跃用户按天明细'
PARTITIONED BY ( `dt` string)
stored as  parquet
location '/warehouse/gmall/dws/dws_uv_detail_day/'
;

数据导入

按周分区；过滤出一周内的数据；按设备id分组；===>count（*）得到最终结果；

partition(dt='2019-02-10') from dwd_start_log where dt='2019-02-10' group by mid_id ( mid_id设备唯一标示 )

以用户单日访问为key进行聚合，如果某个用户在一天中使用了两种操作系统、两个系统版本、多个地区，登录不同账号，只取其中之一

hive (gmall)>
set hive.exec.dynamic.partition.mode=nonstrict;

insert overwrite table dws_uv_detail_day  partition(dt='2019-02-10')
select  
    mid_id,
    concat_ws('|', collect_set(user_id)) user_id,
    concat_ws('|', collect_set(version_code)) version_code,
    concat_ws('|', collect_set(version_name)) version_name,
    concat_ws('|', collect_set(lang))lang,
    concat_ws('|', collect_set(source)) source,
    concat_ws('|', collect_set(os)) os,
    concat_ws('|', collect_set(area)) area, 
    concat_ws('|', collect_set(model)) model,
    concat_ws('|', collect_set(brand)) brand,
    concat_ws('|', collect_set(sdk_version)) sdk_version,
    concat_ws('|', collect_set(gmail)) gmail,
    concat_ws('|', collect_set(height_width)) height_width,
    concat_ws('|', collect_set(app_time)) app_time,
    concat_ws('|', collect_set(network)) network,
    concat_ws('|', collect_set(lng)) lng,
    concat_ws('|', collect_set(lat)) lat
from dwd_start_log
where dt='2019-02-10'  
group by mid_id;

查询导入结果；

hive (gmall)> select * from dws_uv_detail_day limit 1;

###最后count(*)即是每日活跃设备的个数；
hive (gmall)> select count(*) from dws_uv_detail_day;

2 每周（dws_uv_detail_wk）活跃设备明细 partition(wk_dt)

周一到周日concat(date_add(next_day('2019-02-10', 'MO'), -7), '_', date_add(next_day('2019-02-10', 'MO'), -1))即 2019-02-04_2019-02-10

创建分区表：partitioned by('wk_dt' string)

hive (gmall)>
drop table if exists dws_uv_detail_wk;

create table dws_uv_detail_wk( 
    `mid_id` string COMMENT '设备唯一标识',
    `user_id` string COMMENT '用户标识', 
    `version_code` string COMMENT '程序版本号', 
    `version_name` string COMMENT '程序版本名', 
`lang` string COMMENT '系统语言', 
`source` string COMMENT '渠道号', 
`os` string COMMENT '安卓系统版本', 
`area` string COMMENT '区域', 
`model` string COMMENT '手机型号', 
`brand` string COMMENT '手机品牌', 
`sdk_version` string COMMENT 'sdkVersion', 
`gmail` string COMMENT 'gmail', 
`height_width` string COMMENT '屏幕宽高',
`app_time` string COMMENT '客户端日志产生时的时间',
`network` string COMMENT '网络模式',
`lng` string COMMENT '经度',
`lat` string COMMENT '纬度',
    `monday_date` string COMMENT '周一日期',
    `sunday_date` string COMMENT  '周日日期' 
) COMMENT '活跃用户按周明细'
PARTITIONED BY (`wk_dt` string)
stored as  parquet
location '/warehouse/gmall/dws/dws_uv_detail_wk/'
;

导入数据：以周为分区；过滤出一个月内的数据，按设备id分组；

周一：date_add(next_day('2019-05-16','MO'),-7);

周日：date_add(next_day('2019-05-16','MO'),-1);

周一---周日：concat(date_add(next_day('2019-05-16', 'MO'), -7), "_", date_add(next_day('2019-05-16', 'MO'), -1));

insert overwrite table dws_uv_detail_wk partition(wk_dt)
select mid_id,
concat_ws('|', collect_set(user_id)) user_id,
concat_ws('|', collect_set(version_code)) version_code,
concat_ws('|', collect_set(version_name)) version_name,
concat_ws('|', collect_set(lang)) lang,
concat_ws('|', collect_set(source)) source,
concat_ws('|', collect_set(os)) os,
concat_ws('|', collect_set(area)) area, 
concat_ws('|', collect_set(model)) model,
concat_ws('|', collect_set(brand)) brand,
concat_ws('|', collect_set(sdk_version)) sdk_version,
concat_ws('|', collect_set(gmail)) gmail,
concat_ws('|', collect_set(height_width)) height_width,
concat_ws('|', collect_set(app_time)) app_time,
concat_ws('|', collect_set(network)) network,
concat_ws('|', collect_set(lng)) lng,
concat_ws('|', collect_set(lat)) lat,
date_add(next_day('2019-02-10', 'MO'), -7),
date_add(next_day('2019-02-10', 'MO'), -1),
concat(date_add(next_day('2019-02-10', 'MO'), -7), '_', date_add(next_day('2019-02-10', 'MO'), -1))
from dws_uv_detail_day
where dt >= date_add(next_day('2019-02-10', 'MO'), -7) and dt <= date_add(next_day('2019-02-10', 'MO'), -1)
group by mid_id;

查询导入结果

hive (gmall)> select * from dws_uv_detail_wk limit 1;
hive (gmall)> select count(*) from dws_uv_detail_wk;

3 每月活跃设备明细 dws_uv_detail_mn partition(mn) - 把每日的数据插入进去

DWS层创建分区表 partitioned by(mn string)

hive (gmall)>
drop table if exists dws_uv_detail_mn;

create  external table dws_uv_detail_mn( 
    `mid_id` string COMMENT '设备唯一标识',
    `user_id` string COMMENT '用户标识', 
    `version_code` string COMMENT '程序版本号', 
    `version_name` string COMMENT '程序版本名', 
`lang` string COMMENT '系统语言', 
`source` string COMMENT '渠道号', 
`os` string COMMENT '安卓系统版本', 
`area` string COMMENT '区域', 
`model` string COMMENT '手机型号', 
`brand` string COMMENT '手机品牌', 
`sdk_version` string COMMENT 'sdkVersion', 
`gmail` string COMMENT 'gmail', 
`height_width` string COMMENT '屏幕宽高',
`app_time` string COMMENT '客户端日志产生时的时间',
`network` string COMMENT '网络模式',
`lng` string COMMENT '经度',
`lat` string COMMENT '纬度'
) COMMENT '活跃用户按月明细'
PARTITIONED BY (`mn` string)
stored as  parquet
location '/warehouse/gmall/dws/dws_uv_detail_mn/'
;

数据导入按月分区；过滤出一个月内的数据，按照设备id分组；

data_format('2019-03-10', 'yyyy-MM') ---> 2019-03

where date_format('dt', 'yyyy-MM') = date_format('2019-02-10', 'yyyy-MM') group by mid_id;

hive (gmall)>
set hive.exec.dynamic.partition.mode=nonstrict;

insert  overwrite table dws_uv_detail_mn  partition(mn)
select  
    mid_id,
    concat_ws('|', collect_set(user_id)) user_id,
    concat_ws('|', collect_set(version_code)) version_code,
    concat_ws('|', collect_set(version_name)) version_name,
    concat_ws('|', collect_set(lang)) lang,
    concat_ws('|', collect_set(source)) source,
    concat_ws('|', collect_set(os)) os,
    concat_ws('|', collect_set(area)) area, 
    concat_ws('|', collect_set(model)) model,
    concat_ws('|', collect_set(brand)) brand,
    concat_ws('|', collect_set(sdk_version)) sdk_version,
    concat_ws('|', collect_set(gmail)) gmail,
    concat_ws('|', collect_set(height_width)) height_width,
    concat_ws('|', collect_set(app_time)) app_time,
    concat_ws('|', collect_set(network)) network,
    concat_ws('|', collect_set(lng)) lng,
    concat_ws('|', collect_set(lat)) lat,
    date_format('2019-02-10','yyyy-MM')
from dws_uv_detail_day
where date_format(dt,'yyyy-MM') = date_format('2019-02-10','yyyy-MM')   
group by mid_id;

查询导入结果

hive (gmall)> select * from dws_uv_detail_mn limit 1;
hive (gmall)> select count(*) from dws_uv_detail_mn ;

脚本执行时间；企业开发中一般在每日凌晨30分~1点

ADS层目标：当日、当周、当月活跃设备数使用 day_count表 join wk_count join mn_count , 把3张表连接一起

建表ads_uv_count表：

字段有day_count、wk_count、mn_count is_weekend if(date_add(next_day('2019-02-10', 'MO'), -1) = '2019-02-10', 'Y', 'N') is_monthend if(last_day('2019-02-10') = '2019-02-10', 'Y', 'N')

drop table if exists ads_uv_count;

需求二：用户新增主题

首次联网使用应用的用户。如果一个用户首次打开某APP，那这个用户定义为新增用户；卸载再安装的设备，不会被算作一次新增。新增用户包括日新增用户、周新增用户、月新增用户。

每日新增(老用户不算,之前没登陆过，今天是第一次登陆)设备--没有分区 -->以往的新增库里边没有他，但他今天活跃了即新增加的用户；

1 DWS层（每日新增设备明细表）创建每日新增设备明细表：dws_new_mid_day

hive (gmall)>
drop table if exists  dws_new_mid_day;
create  table  dws_new_mid_day
(
    `mid_id` string COMMENT '设备唯一标识',
    `user_id` string COMMENT '用户标识', 
    `version_code` string COMMENT '程序版本号', 
    `version_name` string COMMENT '程序版本名', 
`lang` string COMMENT '系统语言', 
`source` string COMMENT '渠道号', 
`os` string COMMENT '安卓系统版本', 
`area` string COMMENT '区域', 
`model` string COMMENT '手机型号', 
`brand` string COMMENT '手机品牌', 
`sdk_version` string COMMENT 'sdkVersion', 
`gmail` string COMMENT 'gmail', 
`height_width` string COMMENT '屏幕宽高',
`app_time` string COMMENT '客户端日志产生时的时间',
`network` string COMMENT '网络模式',
`lng` string COMMENT '经度',
`lat` string COMMENT '纬度',
    `create_date`  string  comment '创建时间' 
)  COMMENT '每日新增设备信息'
stored as  parquet
location '/warehouse/gmall/dws/dws_new_mid_day/';

dws_uv_detail_day(每日活跃设备明细) left join dws_new_mid_day nm(以往的新增用户表, 新建字段create_time2019-02-10) nm.mid_id is null;

导入数据

用每日活跃用户表 left join 每日新增设备表，关联的条件是mid_id相等。如果是每日新增的设备，则在每日新增设备表中为null。

from dws_uv_detail_day ud left join dws_new_mid_day nm on ud.mid_id=nm.mid_id

where ud.dt='2019-02-10' and nm.mid_id is null;

hive (gmall)>
insert into table dws_new_mid_day  
select  
    ud.mid_id,
    ud.user_id , 
    ud.version_code , 
    ud.version_name , 
    ud.lang , 
    ud.source, 
    ud.os, 
    ud.area, 
    ud.model, 
    ud.brand, 
    ud.sdk_version, 
    ud.gmail, 
    ud.height_width,
    ud.app_time,
    ud.network,
    ud.lng,
    ud.lat,
    '2019-02-10'
from dws_uv_detail_day ud left join dws_new_mid_day nm on ud.mid_id=nm.mid_id
where ud.dt='2019-02-10' and nm.mid_id is null;

查询导入数据

hive (gmall)> select count(*) from dws_new_mid_day ;

2 ADS层（每日新增设备表）创建每日新增设备表ads_new_mid_count

hive (gmall)>
drop table if exists  `ads_new_mid_count`;
create  table  `ads_new_mid_count`
(
    `create_date`     string  comment '创建时间' ,
    `new_mid_count`   BIGINT comment '新增设备数量' 
)  COMMENT '每日新增设备信息数量'
row format delimited  fields terminated by '\t' 
location '/warehouse/gmall/ads/ads_new_mid_count/';

导入数据 count（*） dws_new_mid_day表即可

加了create_date就必须group by create_time，否则报错：not in GROUP BY key 'create_date'

hive (gmall)>
insert into table ads_new_mid_count 
select create_date , count(*)  from dws_new_mid_day
where create_date='2019-02-10'
group by create_date ;

查询导入数据

hive (gmall)> select * from ads_new_mid_count;

扩展每月新增：

--每月新增

create table dws_new_mid_mn(
    `mid_id` string COMMENT '设备唯一标识',
    `user_id` string COMMENT '用户标识',

需求三：用户留存主题

如果不考虑2019-02-11和2019-02-12的新增用户：2019-02-10新增100人，一天后它的留存率是30%，2天12号它的留存率是25%，3天后留存率32%；

站在2019-02-12号看02-11的留存率：新增200人，12号的留存率是20%；

站在2019-02-13号看02-12的留存率：新增100人，13号即一天后留存率是25%；

用户留存率的分析：昨日的新增且今天是活跃的 / 昨日的新增用户量

如今天11日，要统计10日的用户留存率---->10日的新设备且是11日活跃的 / 10日新增设备　　分母：10日的新增设备(每日活跃 left join 以往新增设备表(nm) nm.mid_id is null ) 　　分子：每日活跃表(ud) join 每日新增表(nm) where ud.dt='今天' and nm.create_date = '昨天'

① DWS层（每日留存用户明细表dws_user_retention_day）用户1天留存的分析：===>>

留存用户=前一天新增 join 今天活跃

   用户留存率=留存用户/前一天新增

创建表：dws_user_retention_day

hive (gmall)>
drop table if exists  `dws_user_retention_day`;
create  table  `dws_user_retention_day`

PARTITIONED BY ( `dt` string)
stored as  parquet
location '/warehouse/gmall/dws/dws_user_retention_day/'
;

导入数据（每天计算前1天的新用户访问留存明细）

from dws_uv_detail_day每日活跃设备 ud join dws_new_mid_day每日新增设备 nm on ud.mid_id =nm.mid_id where ud.dt='2019-02-11' and nm.create_date=date_add('2019-02-11',-1);

hive (gmall)>

查询导入数据（每天计算前1天的新用户访问留存明细）

hive (gmall)> select count(*) from dws_user_retention_day;

② DWS层（1,2,3,n天留存用户明细表）直接插入数据：dws_user_retention_day 用union all连接起来，汇总到一个表中；1）直接导入数据（每天计算前1,2,3，n天的新用户访问留存明细）直接改变这个即可以，date_add('2019-02-11',-3); -1是一天的留存率；-2是两天的留存率、-3是三天的留存率

hive (gmall)>
insert  overwrite table dws_user_retention_day  partition(dt="2019-02-11")
select

where ud.dt='2019-02-11' and nm.create_date=date_add('2019-02-11',-3);

2）查询导入数据（每天计算前1,2,3天的新用户访问留存明细）

hive (gmall)> select retention_day , count(*) from dws_user_retention_day group by retention_day;

③ ADS层留存用户数 ads_user_retention_day_count 直接count( * )即可 1）创建 ads_user_retention_day_count表：

hive (gmall)>
drop table if exists  `ads_user_retention_day_count`;
create  table  `ads_user_retention_day_count` 
(
   `create_date`       string  comment '设备新增日期',
   `retention_day`     int comment '截止当前日期留存天数',
   `retention_count`    bigint comment  '留存数量'
)  COMMENT '每日用户留存情况'
stored as  parquet
location '/warehouse/gmall/ads/ads_user_retention_day_count/';

导入数据按创建日期create_date 和留存天数retention_day进行分组group by；

hive (gmall)>
insert into table ads_user_retention_day_count 
select   
    create_date, 
    retention_day, 
    count(*) retention_count  
from dws_user_retention_day
where dt='2019-02-11' 
group by create_date,retention_day;

查询导入数据

hive (gmall)> select * from ads_user_retention_day_count;

---> 2019-02-10 1 112

④ 留存用户比率 retention_count / new_mid_count 即留存个数 / 新增个数创建表 ads_user_retention_day_rate

hive (gmall)>
drop table if exists  `ads_user_retention_day_rate`;
create  table  `ads_user_retention_day_rate` 
(
     `stat_date`          string comment '统计日期',
     `create_date`       string  comment '设备新增日期',
     `retention_day`     int comment '截止当前日期留存天数',
     `retention_count`    bigint comment  '留存数量',
     `new_mid_count`     string  comment '当日设备新增数量',
     `retention_ratio`   decimal(10,2) comment '留存率'
)  COMMENT '每日用户留存情况'
stored as  parquet
location '/warehouse/gmall/ads/ads_user_retention_day_rate/';

导入数据

join ads_new_mid_countt --->每日新增设备表

hive (gmall)>
insert into table ads_user_retention_day_rate

    where dt='2019-02-11' 
    group by create_date,retention_day
)  ur join ads_new_mid_count nc on nc.create_date=ur.create_date;

查询导入数据

hive (gmall)>select * from ads_user_retention_day_rate;

数据导入脚本

1）在/home/kris/bin目录下创建脚本ads_sale.sh

[kris@hadoop101 bin]$ vim ads_sale.sh

#!/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="

set hive.exec.dynamic.partition.mode=nonstrict;

insert into table "$APP".ads_sale_tm_category1_stat_mn
select   
    mn.sku_tm_id,

品牌复购率结果输出到MySQL

1）在MySQL中创建ads_sale_tm_category1_stat_mn表

create  table ads_sale_tm_category1_stat_mn
(   
    tm_id varchar(200) comment '品牌id ' ,
    category1_id varchar(200) comment '1级品类id ',
    category1_name varchar(200) comment '1级品类名称 ',
    buycount   varchar(200) comment  '购买人数',
    buy_twice_last varchar(200) comment '两次以上购买人数',
    buy_twice_last_ratio varchar(200) comment  '单次复购率', 
    buy_3times_last   varchar(200) comment   '三次以上购买人数',
    buy_3times_last_ratio varchar(200)  comment  '多次复购率' ,
    stat_mn varchar(200) comment '统计月份',
    stat_date varchar(200) comment '统计日期' 
)

2）编写Sqoop导出脚本

在/home/kris/bin目录下创建脚本sqoop_export.sh

[kris@hadoop101 bin]$ vim sqoop_export.sh

#!/bin/bash

db_name=gmall

export_data() {
/opt/module/sqoop/bin/sqoop export \
--connect "jdbc:mysql://hadoop101:3306/${db_name}?useUnicode=true&characterEncoding=utf-8"  \
--username root \
--password 123456 \
--table $1 \
--num-mappers 1 \
--export-dir /warehouse/$db_name/ads/$1 \
--input-fields-terminated-by "\t"  \
--update-key "tm_id,category1_id,stat_mn,stat_date" \
--update-mode allowinsert \
--input-null-string '\\N'    \
--input-null-non-string '\\N'  
}

case $1 in
  "ads_sale_tm_category1_stat_mn")
     export_data "ads_sale_tm_category1_stat_mn"
;;
   "all")
     export_data "ads_sale_tm_category1_stat_mn"
;;
esac

3）执行Sqoop导出脚本

[kris@hadoop101 bin]$ chmod 777 sqoop_export.sh

[kris@hadoop101 bin]$ sqoop_export.sh all

4）在MySQL中查看结果

SELECT * FROM ads_sale_tm_category1_stat_mn;

需求十二：求每个等级的用户对应的复购率前十的商品排行

1）每个等级，每种商品，买一次的用户数，买两次的用户数=》得出复购率

2）利用开窗函数，取每个等级的前十

3）形成脚本

用户购买明细宽表 dws_sale_detail_daycount

① t1--按user_leval, sku_id, user_id统计下单次数

select 
    user_level, 
    sku_id, 
    user_id, 
    sum(order_count) order_count_sum
from dws_sale_detail_daycount
where date_format(dt, 'yyyy-MM') = date_format('2019-02-13', 'yyyy-MM')
group by user_level, sku_id, user_id limit 10;

② t2 --求出每个等级，每种商品，买一次的用户数，买两次的用户数得出复购率

select 
    t1.user_level,
    t1.sku_id,
    sum(if(t1.order_count_sum > 0, 1, 0)) buyOneCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) buyTwiceCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) / sum(if(t1.order_count_sum > 0, 1, 0)) * 100 buyTwiceCountRatio,
    '2019-02-13' stat_date
from(
select 
    user_level, 
    sku_id, 
    user_id, 
    sum(order_count) order_count_sum
from dws_sale_detail_daycount
where date_format(dt, 'yyyy-MM') = date_format('2019-02-13', 'yyyy-MM')
group by user_level, sku_id, user_id
) t1
group by t1.user_level, t1.sku_id;

③ t3 --按用户等级分区，复购率排序

select
    t2.user_level,
    t2.sku_id,
    t2.buyOneCount,
    t2.buyTwiceCount,
    t2.buyTwiceCountRatio,
    t2.stat_date
from(
select 
    t1.user_level,
    t1.sku_id,
    sum(if(t1.order_count_sum > 0, 1, 0)) buyOneCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) buyTwiceCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) / sum(if(t1.order_count_sum > 0, 1, 0)) * 100 buyTwiceCountRatio,
    '2019-02-13' stat_date
from(
select 
    user_level, 
    sku_id, 
    user_id, 
    sum(order_count) order_count_sum
from dws_sale_detail_daycount
where date_format(dt, 'yyyy-MM') = date_format('2019-02-13', 'yyyy-MM')
group by user_level, sku_id, user_id
) t1
group by t1.user_level, t1.sku_id
)t2

④ -分区排序 rank()

select
    t2.user_level,
    t2.sku_id,
    t2.buyOneCount,
    t2.buyTwiceCount,
    t2.buyTwiceCountRatio,
rank() over(partition by t2.sku_id order by t2.buyTwiceCount) rankNo
from(
select 
    t1.user_level,
    t1.sku_id,
    sum(if(t1.order_count_sum > 0, 1, 0)) buyOneCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) buyTwiceCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) / sum(if(t1.order_count_sum > 0, 1, 0)) * 100 buyTwiceCountRatio,
    '2019-02-13' stat_date
from(
select 
    user_level, 
    sku_id, 
    user_id, 
    sum(order_count) order_count_sum
from dws_sale_detail_daycount
where date_format(dt, 'yyyy-MM') = date_format('2019-02-13', 'yyyy-MM')
group by user_level, sku_id, user_id
) t1
group by t1.user_level, t1.sku_id
)t2

⑤ 作为子查询取前10

select t3.user_level, t3.sku_id, t3.buyOneCount, t3.buyTwiceCount, t3.buyTwiceCountRatio, t3.rankNo
from(
select
    t2.user_level,
    t2.sku_id,
    t2.buyOneCount,
    t2.buyTwiceCount,
    t2.buyTwiceCountRatio,
rank() over(partition by t2.sku_id order by t2.buyTwiceCount) rankNo
from(
select 
    t1.user_level,
    t1.sku_id,
    sum(if(t1.order_count_sum > 0, 1, 0)) buyOneCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) buyTwiceCount,
    sum(if(t1.order_count_sum > 1, 1, 0)) / sum(if(t1.order_count_sum > 0, 1, 0)) * 100 buyTwiceCountRatio,
    '2019-02-13' stat_date
from(
select 
    user_level, 
    sku_id, 
    user_id, 
    sum(order_count) order_count_sum
from dws_sale_detail_daycount
where date_format(dt, 'yyyy-MM') = date_format('2019-02-13', 'yyyy-MM')
group by user_level, sku_id, user_id
) t1
group by t1.user_level, t1.sku_id
)t2
) t3 where rankNo <= ;
