如果我有一个像这样的表：
LOCATION CODE COMPANY PRICE
--------- ---- ------- ----------
Sydney | A | ACME | 1200
Brisbane | C | WONKA | 3000
Melbourne | B | ACME | 500
Sydney | A | ACME | 100
Brisbane | A | WONKA | 1000
Melbourne | C | ACME | 7000
Sydney | A | ACME | 800
Brisbane | B | WONKA | 900
Melbourne | C | WONKA | 200
Sydney | C | ACME | 400
Brisbane | B | ACME | 1200
Melbourne | D | WONKA | 600
Sydney | A | ACME | 3000
Brisbane | A | WONKA | 400
Melbourne | C | WONKA | 1400
Sydney | A | ACME | 1600
Brisbane | A | WONKA | 700
Melbourne | A | ACME | 800
我想获得类似的东西
LOCATION CODE COMPANY SUM(PRICE)
--------- ---- ----- ----------
Brisbane | A | WONKA | 2100
Brisbane | B | ACME | 1200
Brisbane | B | WONKA | 900
Brisbane | C | WONKA | 3000
Brisbane | | | 7200
Melbourne | A | ACME | 800
Melbourne | B | ACME | 500
Melbourne | C | ACME | 7000
Melbourne | C | WONKA | 1600
Melbourne | D | WONKA | 600
Melbourne | | | 10500
Sydney | A | ACME | 6700
Sydney | C | ACME | 400
Sydney | | | 7100
这是按位置，代码和公司分组的价格总计，其中有价格小计行（仅按位置分组）。
第一部分可以通过以下查询来实现：
with sample_tab as
(
select 'Sydney' location,'A' code, 'ACME' company, 1200 price from dual
union all
select 'Brisbane' location,'C' code, 'WONKA' company, 3000 price from dual
union all
select 'Melbourne' location,'B' code, 'ACME' company, 500 price from dual
union all
select 'Sydney' location,'A' code, 'ACME' company, 100 price from dual
union all

)
select location,code,company,sum(price)
from sample_tab
group by location,code,company
order by location;
，但不确定如何获取按位置分类汇总的行。 可以使用汇总分析功能或其他功能来实现吗？
答案 0 :(得分：3)
因此，您需要所谓的“汇总总计”-但仅适用于一列。那是部分汇总。此外，您需要每对（代码，公司）的总数，而不是每个单独的代码或公司的总数。这在Oracle rollup语法中是可能的，从技术上讲，它是“复合列”（语法是将对对用圆括号括起来，除了汇总所需的括号外）。将关键字rollup后的双括号替换为单括号并比较结果-不是将是您想要的。
因此，这是查询：
select location,code,company,sum(price)
from sample_tab
group by location,rollup((code,company)) -- partial rollup on composite column
order by location,code,company; -- add code and company to order by
答案 1 :(得分：1)
替代解决方案或面向将来希望在没有rollup
sums as (
select location, code, company,sum(price) price
from sample_tab
group by location, code, company),
subgroup as (
select location, '','', sum(price) price
from sample_tab
group by location)
select *
from sums
union all
select *
from subgroup
order by location;
