Hive 在分区上嵌套 SUM - 错误表达式不在 GROUP BY 键中

Question

我试图在一个查询中获得累积总和。它在 SQL、PRESTO 等中运行良好，但在 HIVE 中却不行，这会引发错误消息。

create table test(store varchar(10), item int, quantity int)
insert into test
select 'depot',101,1
union select 'depot',101,2
union select 'depot',101,5
union select 'depot',102,1
union select 'depot',102,3

store	item	revenue
depot	101	1
depot	101	2
depot	101	5
depot	102	1
depot	102	3

select store, item,
sum(sum(revenue)) over (partition by store order by item)
from test
group by store, item

预期输出：

store	item	quantity
depot	101	8
depot	102	12

错误：

[代码：40000，SQL 状态：42000] 编译语句时出错： 失败：SemanticException 无法将窗口调用分解为 团体。至少 1 个组必须仅依赖于输入列。还要检查 对于循环依赖。潜在错误： org.apache.hadoop.hive.ql.parse.SemanticException：第 1:24 行 表达式不在 GROUP BY 键“收入”中

有什么建议吗？

Answer 1

您可以将查询分开：

select store, item, sum(sum_revenue) over (partition by store order by item) as revenue
from (
    select store, item, sum(revenue) as sum_revenue
    from test
    group by store, item
) as t
