分析数据

trade_type=0是正常交易；trade_type=5是取消订单

sql 复制代码

select trade_date,
       store_no,
       goods_no,
       (count(distinct if(trade_type=0,parent_order_no,null)) - count(distinct if(trade_type = 5,parent_order_no,null))) `销售单量`,
       sum(if(trade_type=0,sale_qty,0)) - sum(if(trade_type=5,sale_qty,0)) as `销售数量`,
       sum(if(trade_type=0,sale_amount,0))-sum(if(trade_type=5,sale_amount,0)) `销售金额`,
       count(distinct if(trade_type=0 and is_online_order = 1,parent_order_no,null))
           -count(distinct if(trade_type=5 and is_online_order = 1,parent_order_no,null)) `线上单量`,
       count(distinct if(trade_type=0 and is_online_order = 0,parent_order_no,null))
           -count(distinct if(trade_type=5 and is_online_order = 0,parent_order_no,null)) `线下单量`
from dwm_sold_goods_sold_dtl_i
where trade_date = '2024-01-01'
group by trade_date, store_no, goods_no;

总结

复制代码

因为要排除取消订单的那个值。还要去重复值。
-- count(distinct if(trade_type=0, parent_order_no, null)) as 正常交易的订单量,
-- count(distinct if(trade_type=5, parent_order_no, null)) as 取消交易的订单量,
