Question

 select
COUNT(pc.property_id) AS [Total Count of Closed],
SUM(pc.sale_price) AS [Total Sum of Sales Price],
SUM(pc.advanced_seller_proceeds) AS [Total Sum of Net Proceeds],
SUM(pc.sale_price) * 100 / SUM(pc.sale_price) AS [Percentage of Total Sales Price],
SUM(pc.advanced_seller_proceeds) * 100 / SUM(pc.advanced_seller_proceeds) AS [Percentage of Total Net Proceeds],

AVG(DATEDIFF(day,pd.list_dt,pc.close_dt)) AS [Average Days from List Date to Close Date]
 from resnet_mysql.dbo.property_closings pc
join resnet_mysql.dbo.property_details pd
    on pc.property_id = pd.property_id

 where pc.res_id = 201

我正在努力获得总销售价格的百分比，但我一直保持100％。请帮忙。

Here is a screenshot

Answer 1

我认为你想要窗口功能。我还明确地使用非整数 - 以防万一（SQL Server对整数进行整数除法，因此1/2 = 0而不是0.5）：

SUM(pc.sale_price) * 100.0 / SUM(SUM(pc.sale_price) OVER () AS [Percentage of Total Sales Price],
SUM(pc.advanced_seller_proceeds) * 100.0 / SUM(SUM(pc.advanced_seller_proceeds)) OVER () AS [Percentage of Total Net Proceeds],

请注意SUM(SUM())和OVER ()。它们取所有行的值之和。

Answer 2

SUM(SUM(pc.sale_price)) OVER ()使用窗口化聚合对总和进行求和：

SUM(pc.sale_price) * 100 / SUM(SUM(pc.sale_price)) OVER () AS [Percentage of Total Sales Price],
SUM(pc.advanced_seller_proceeds) * 100 / SUM(SUM(pc.advanced_seller_proceeds)) OVER () AS [Percentage of Total Net Proceeds],
