正在计算报表查询的加权总和和列总和 SQL

Question

我有一个 excel sheet，其中有一个我需要在报告中显示的示例数据。

可以看出，高亮显示的10%是用公式C11/C21计算出来的。对于第一条记录，C11 = 3900 和 C21 = 37250（所有 PO 金额列的总和）。所以 (3900/37250) * 100 = 0.104697 * 100 = 10.4697 或 10%

同样，总加权是所有加权值列值的总和。

现在我先做了样本数据

CREATE TABLE sample_po_data ("PO_NUMBER", "PO_AMOUNT", "TASK_NAME") AS
  SELECT 4567, 3900, 'Plumbing Rough' FROM DUAL
UNION ALL SELECT 5678, 8000, 'Pour Floor' FROM DUAL
UNION ALL SELECT 6789, 15000, 'Framing' FROM DUAL
UNION ALL SELECT 8945, 2500, 'Windows' FROM DUAL
UNION ALL SELECT 5432, 3500, 'Electric' FROM DUAL
UNION ALL SELECT 4321, 450, 'LowVolt' FROM DUAL
UNION ALL SELECT 1234, 3900, 'HVAC Rough' FROM DUAL;

然后我使用了下面的查询

select 
    PO_NUMBER AS "PO #",
    Round((PO_AMOUNT / SUM(PO_AMOUNT) OVER ())*100) || '%' as "Weighted Value",
    PO_AMOUNT AS "PO Amount", 
    Round((PO_AMOUNT / SUM(PO_AMOUNT) OVER ())*100) || '%' as "Total Percent Complete",
    SUM(PO_AMOUNT) OVER () AS "Total Committed And Budgeted"
    -- SUM(Round((PO_AMOUNT / SUM(PO_AMOUNT) OVER ())*100)) OVER () || '%' as "Total Weighted"  -- Total weighted   (Sum of all Weighted Value Column)
    -- % Completed      (Sum of all Total Percent Complete Column)
from sample_po_data;

以上查询给出了以下结果

现在如何对 Weighted Value 和 Total Percent Complete 列求和？两者相同。

另外我想问一下上面的查询是否正确或者有什么更好的方法来写上面的查询。实际上我在 select 中使用了 SUM(PO_AMOUNT) 三次。我的两列也是一样的。

Total Committed And Budgeted column 与所有记录一起出现。虽然我只需要一次。 Total weighted column 和 % Completed column.

也是如此

如何改进此查询？

谢谢

使用SUM作为解析函数和条件聚合：

select 
    PO_NUMBER AS "PO #",
    Round(PO_AMOUNT / SUM(PO_AMOUNT) OVER () * 100) AS "Weighted Value",
    PO_AMOUNT AS "PO Amount",
    Completion_Date,
    Round(
      CASE WHEN completion_date IS NULL THEN 0 ELSE PO_AMOUNT END
      / SUM(PO_AMOUNT) OVER () * 100
    ) AS "Percent Complete",
    SUM(PO_AMOUNT) OVER () AS "Total Committed And Budgeted",
    -- This will always add up to 100%; you do not need to calculate it.
    100 as "Total Weighted",
    Round(
      SUM(CASE WHEN completion_date IS NULL THEN 0 ELSE PO_AMOUNT END) OVER ()
      / SUM(PO_AMOUNT) OVER () * 100
    ) AS "Total Percent Complete"
from sample_po_data;

其中，对于示例数据（添加了 COMPLETION_DATE 列）：

CREATE TABLE sample_po_data (PO_NUMBER, PO_AMOUNT, COMPLETION_DATE, TASK_NAME) AS
          SELECT 4567,  3900, DATE '2021-01-01', 'Plumbing Rough' FROM DUAL
UNION ALL SELECT 5678,  8000, DATE '2021-02-01', 'Pour Floor' FROM DUAL
UNION ALL SELECT 6789, 15000, DATE '2021-03-01', 'Framing' FROM DUAL
UNION ALL SELECT 8945,  2500, NULL,              'Windows' FROM DUAL
UNION ALL SELECT 5432,  3500, NULL,              'Electric' FROM DUAL
UNION ALL SELECT 4321,   450, NULL,              'LowVolt' FROM DUAL
UNION ALL SELECT 1234,  3900, NULL,              'HVAC Rough' FROM DUAL;

输出：

PO # Weighted Value PO Amount COMPLETION_DATE Percent Complete Total Committed And Budgeted Total Weighted Total Percent Complete

4567 10 3900 01-JAN-21 10 37250 100 72

5432 9 3500 0 37250 100 72
