最近7/30日各品牌復購率

統(tǒng)計周期	統(tǒng)計粒度	指標	說明
最近7、30日	品牌	復購率	重復購買人數(shù)占購買人數(shù)比例

1.表結構

?2.數(shù)據(jù)來源

?實現(xiàn)1：

(1) 將每個用戶購買每個品牌的次數(shù)進行聚合user_tm_count

select user_id,tm_id,tm_name,sum(order_count_7d) user_tm_countfrom dws_trade_user_sku_order_ndwhere dt = '2020-06-14'group by user_id, tm_id, tm_name

?

（2）按品牌分組用大于等于2的user_tm_count÷大于等于1的user_tm_count

selecttm_id,tm_name,sum(`if`(user_tm_count>=2,1,0)) / sum(`if`(user_tm_count>=1,1,0)) from (select user_id,tm_id,tm_name,sum(order_count_7d) user_tm_countfrom dws_trade_user_sku_order_ndwhere dt = '2020-06-14'group by user_id, tm_id, tm_name)t1 group by tm_id,tm_name

?（3）將7、30天數(shù)據(jù)合并

select recent_days,tm_id,tm_name,sum(`if`(user_tm_count >= 2, 1, 0)) / sum(`if`(user_tm_count >= 1, 1, 0)) from (select recent_days,user_id,tm_id,tm_name,sum(`if`(recent_days = 7, order_count_7d, order_count_30d)) user_tm_countfrom dws_trade_user_sku_order_nd lateral view explode(array(7, 30)) tmp as recent_dayswhere dt = '2020-06-14'group by recent_days, user_id, tm_id, tm_name) t1 group by recent_days,tm_id, tm_name select'2020-06-14' dt,recent_days,tm_id,tm_name,cast(sum(if(order_count>=2,1,0))/sum(if(order_count>=1,1,0)) as decimal(16,2)) from (select'2020-06-14' dt,recent_days,user_id,tm_id,tm_name,sum(order_count) order_countfrom(selectrecent_days,user_id,tm_id,tm_name,case recent_dayswhen 7 then order_count_7dwhen 30 then order_count_30dend order_countfrom dws_trade_user_sku_order_nd lateral view explode(array(7,30)) tmp as recent_dayswhere dt='2020-06-14')t1group by recent_days,user_id,tm_id,tm_name )t2 group by recent_days,tm_id,tm_name;
