查找构成聚合查询的值

Question

我在plsql

中有以下表格

Company | StoreNum | Sku | Units | Dollars

• 首先查询：

  select company, storeNum, sku, SUM(units)  AS Units, SUM(dollars) AS dollars
  FROM Sales
  GROUP BY company, storeNum, sku
  

• 第二个查询：

  select COUNT(DISTINCT company), COUNT(DISTINCT(storeNum), sku, 
  SUM(units)  AS Units, SUM(dollars) AS dollars
  FROM Sales
  GROUP BY sku
  HAVING COUNT(DISTINCT company) >= 2
  

第二个查询获得sku的总计，其中至少有两个companies正在销售sku。我需要一种方法来找出哪家公司，商店组成这个清单？

Answer 1

您可以使用LISTAGG获取以逗号分隔的公司列表和商店列表，如下所示。

SELECT LISTAGG(company,',') WITHIN GROUP (
ORDER BY company) company_list,
  LISTAGG(StoreNum,',') WITHIN GROUP (
ORDER BY storeNum) Store_list,
  COUNT(DISTINCT company),
  COUNT(DISTINCT storeNum),
  sku,
  SUM(units)   AS Units,
  SUM(dollars) AS dollars
FROM Sales
GROUP BY sku
HAVING COUNT(DISTINCT company) >= 2;

注意：这适用于Oracle 11g及更高版本。
