查找值組成的彙總查詢

Question

我在PLSQL

Company | StoreNum | Sku | Units | Dollars 

• 首先查詢下表：

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

• 第二個查詢：

  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 
  

第二個查詢獲得sku的總計，其中至少兩個companies銷售sku。我需要一種方法能夠找出公司，商店是否構成這個清單？

Answer 1

您可以使用LISTAGG獲取逗號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：這適用於Oracle 11g以上。
