Question

我在BQ中有销售数据，其中包含以下列 -

Customer Id | ItemID | Order_Qty | Order_Date

我想根据商品的总销售量创建销售排名表。

销售商品的最高排名。

EG。 - 售出总共30个数量的物品abc应该排名1，XYZ项目总共20个销量应该排名2，依此类推。

在我的结果表中，我想要关注列。

ItemId | Total Quantity | Rank

以下是我在遗留SQL格式中的尝试 -

select ItemId ,
       RANK() over (partition by ItemId order by Qty desc) as salesrank
from (SELECT ItemId, sum(order_qty) as Qty
      FROM sales
      group by 1
     )

由于某种原因，所有销售排名都是1

Answer 1

以下是BigQuery Standard SQL

#standardSQL
SELECT 
  ItemID, Total_Quantity, 
  RANK() OVER(ORDER BY Total_Quantity DESC) AS rnk
FROM (
  SELECT ItemID, SUM(Order_Qty) AS Total_Quantity
  FROM sales
  GROUP BY ItemID
)
-- ORDER BY rnk

Answer 2

我猜测你想要排名ean。如果是这样的话：

SELECT ean, SUM(order_qty) as Qty,
       RANK() OVER (ORDER BY SUM(order_qty) DESC) as rnk
FROM sales
GROUP BY ean;

在旧版SQL中，可能是：

SELECT ean, SUM(order_qty) as Qty,
       RANK() OVER (ORDER BY qty DESC) as rnk
FROM sales
GROUP BY ean

根据销售数量为销售的产品创建销售排名表
