计算每月收入的百分比

Question

我有以下基础数据：

+-------+-------+---------------+
| Order | Month | sqft produced |
+-------+-------+---------------+
|  1001 |     4 | 10.29         |
|  1001 |     6 | 4'367.66      |
|  1001 |     7 | 203.57        |
|  1001 |     8 | 294.61        |
|  1001 |     9 | 92.28         |
|  1001 |    10 | 34.47         |
|  1001 |    12 | 16.59         |
|  1002 |     1 | 1.74          |
|  1002 |     4 | 19.54         |
|  1002 |     7 | 5'552.21      |
|  1002 |     9 | 309.62        |
|  1002 |    10 | 24.15         |
|  1002 |    12 | 52.16         |
|  1003 |     5 | 807.45        |
+-------+-------+---------------+

这是三个订单，我想根据每个月生产的平方英尺百分比来分配收入。

收入table：

+-------+-----------+
| Order |  Revenue  |
+-------+-----------+
|  1001 | 1'135'465 |
|  1002 | 1'773'499 |
|  1003 | 172'633   |
+-------+-----------+

所以查询的输出应该是这样的：

+-------+-------+------------------+
| Order | Month | Revenue produced |
+-------+-------+------------------+
|  1001 |     4 | 2'327.72         |
|  1001 |     6 | 988'017.67       |
|  1001 |     7 | 46'050.00        |
|  1001 |     8 | 66'644.36        |
|  1001 |     9 | 20'874.86        |
|  1001 |    10 | 7'797.53         |
|  1001 |    12 | 3'752.86         |
|  1002 |     1 | 517.82           |
|  1002 |     4 | 5'815.02         |
|  1002 |     7 | 1'652'314.97     |
|  1002 |     9 | 92'141.64        |
|  1002 |    10 | 7'186.94         |
|  1002 |    12 | 15'522.60        |
|  1003 |     5 | 172'633.00       |
+-------+-------+------------------+

我正在努力寻找一种获取该格式的基础数据的方法，因为我似乎无法按月拆分它。

Answer 1

让我们称第一个 table sqft 和第二个 revenues。为避免保留字，第一个 table 列的名称将是：

order_id, month_num, sqft_produced

第二个：

order_id, total_revenue

你需要的 SQL 是这样的（这是针对 Oracle 的）：

SELECT order_id, month_num, (sqft_produced / total_sqft * total_revenue) revenue_produced
FROM sqft INNER JOIN
(SELECT order_id, total_sqft, total_revenue FROM (
(SELECT order_id, sum(sqft_produced) total_sqft
GROUP BY order_id) sqfts INNER JOIN revenues ON sqfts.order_id = revenues.order_id)) totals
ON sqft.order_id = totals.order_id;

一步一步：

SELECT order_id, sum(sqft_produced) total_sqft
GROUP BY order_id;

这会得到订单生产的总平方英尺数。

(SELECT order_id, sum(sqft_produced) total_sqft
GROUP BY order_id) sqfts INNER JOIN revenues ON sqfts.order_id = revenues.order_id;

这将为您带来 table 总收入和总平方英尺。

然后您将此 table 加入您的平方英尺 table 并将每月生产的平方英尺除以总平方英尺再乘以总收入，从而将收入按比例分配给平方英尺。

Answer 2

通过将平方英尺除以 [Order] 上分区的平方英尺总和来获得百分比将得到您正在寻找的东西：

select p.[Order], 
       [Month], 
       Revenue, 
       [sqft produced], 
       CAST([sqft produced] / SUM([sqft produced]) OVER(PARTITION BY p.[Order]) AS DECIMAL(10,5)) * 100 as sqft_percentage, 
       Revenue * CAST([sqft produced] / SUM([sqft produced]) OVER(PARTITION BY p.[Order]) AS DECIMAL(10,5)) as revenue_produced
FROM [Orders] p
INNER JOIN Revenue r
ON r.[Order] = p.[Order]
