我正在尝试建立一个查询,以根据商店数量,客户群和品牌分组汇总销售总额的百分比。理想情况下,我希望得到以下结果:
Store --------Segment-------Brand------Sales--------pct_total
1 A X 50 66.6
1 A Y 25 33.3
1 B X 25 25.0
1 B Y 25 25.0
1 B Z 50 50.0
这是我到目前为止与包含此数据所需的表的代码。
select Store,Segment,Brand, to_char(100 * ratio_to_report(total_sales) over (partition by store, segment, brand),'990.00L','NLS_CURRENCY=%') as pct_total
from (
select
Store,
Segment,
Brand,
sum(sales) as total_sales
from customer_data
group by grouping sets ((Store),(store,Segment,brand)))
由于分组,这只是给我一个错误
答案 0 :(得分:0)
不需要分组集,这将返回预期的结果:
select Store,Segment,Brand, total_sales,
to_char(100 * ratio_to_report(total_sales) over (partition by store, segment),'990.00L','NLS_CURRENCY=%') as pct_total
from (
select
Store,
Segment,
Brand,
sum(sales) as total_sales
from customer_data
group by store,Segment,brand)
