汇总分组集

问题描述 投票：0回答：1

我有一个使用 Oracle ROLLUP 函数的表和视图。

请参阅此处的详细信息：dbfiddle。

我想知道是否可以使用 ROLLUP 只计算某些列的总和。例如：

年份 客户 一月 二月 ... 十二月
2023 客户1 第1条 1 1 ... 1
2023 客户1 第2条 1 1 ... 1
2023 客户1 总和 2 2 ... 2
2023 客户1 第3条 1 1 ... 1
2023 客户1 第4条 1 1 ... 1

我希望在 Article1 和 Article2 之后有一个求和行，但不在 Article3 和 Article4 之后。

在fiddle中的示例中，我希望确定是否可以隐藏“Bücher- Warensendungen”出现行下方的“Sum”行。

由于 

mbr_prodgr_id
和 
mbr_prodgr
似乎具有一对一的相关性，因此您似乎不需要 
ROLLUP
两者；只需 
ROLLUP
主键（大概是 
mbr_prodgr_id
）并通过聚合找到另一个。

然后你可以使用：

SELECT year,       
       gp_gr_id,
       mbr_gr_id,
       gp_id,
       bezirk_id,
       mbr_prodgr_id,
       CASE
       WHEN GROUPING_ID(mbr_prodgr_id) = 1
       THEN 'Sum'
       ELSE MAX(mbr_prodgr)
       END AS mbr_prodgr,
       COALESCE(SUM(CASE WHEN month = 4 THEN summe END), 0) AS apr,
       COALESCE(SUM(CASE WHEN month = 5 THEN summe END), 0) AS mai,
       COALESCE(SUM(CASE WHEN month = 6 THEN summe END), 0) AS juni,
       sum(summe) summe_jahr 
FROM   t 
WHERE  deleted =0 
AND    mbr_prodgr_id IS NOT NULL 
GROUP BY 
       year,
       gp_gr_id,
       mbr_gr_id,
       gp_id,
       bezirk_id,
       ROLLUP(mbr_prodgr_id)
HAVING (GROUPING_ID(mbr_prodgr_id), MAX(mbr_prodgr_id)) NOT IN ((1, 12))
ORDER BY
       year,
       gp_gr_id,
       mbr_gr_id,
       gp_id,
       bezirk_id,
       mbr_prodgr_id

或者也许（取决于您是否想使用 

mbr_prodgr_id
或 
mbr_gr_id
进行过滤）：

SELECT year,       
       gp_gr_id,
       mbr_gr_id,
       gp_id,
       bezirk_id,
       mbr_prodgr_id,
       CASE
       WHEN GROUPING_ID(mbr_prodgr_id) = 1
       THEN 'Sum'
       ELSE MAX(mbr_prodgr)
       END AS mbr_prodgr,
       COALESCE(SUM(CASE WHEN month = 4 THEN summe END), 0) AS apr,
       COALESCE(SUM(CASE WHEN month = 5 THEN summe END), 0) AS mai,
       COALESCE(SUM(CASE WHEN month = 6 THEN summe END), 0) AS juni,
       sum(summe) summe_jahr 
FROM   t 
WHERE  deleted =0 
AND    mbr_prodgr_id IS NOT NULL 
GROUP BY 
       year,
       gp_gr_id,
       mbr_gr_id,
       gp_id,
       bezirk_id,
       ROLLUP(mbr_prodgr_id)
HAVING (GROUPING_ID(mbr_prodgr_id), mbr_gr_id) NOT IN ((1, 3))
ORDER BY
       year,
       gp_gr_id,
       mbr_gr_id,
       gp_id,
       bezirk_id,
       mbr_prodgr_id

对于样本数据（取自小提琴）：
