如何在别名列上使用聚合函数SUM？

http://i.stack.imgur.com/L1z4D.jpg 发票ID，采购订单编号和dueDate重复显示。

TotalPrice是一个别名（它应该是单价，总价格是一个错误，所以假设单价不是总价格）

TotalShippingPrice显示与InvoiceID / PONumber关联的运费，对于每个invoiceID / PONumber，将有单一运费。同样的规则适用于跟踪号码。

年份代表发票发送的年份（不用担心）。

isTaxPaid表示是否以单价支付税款（不用担心）

我的要求是：

我需要删除invoiceID复制并且每个发票都有单价的总和，因此每个invoiceID / PONumber只有一个记录，单位价格总和。

例如：

30463 - 903315 - 无论截止日期 - 368（92 + 276） - -----（trackingNumber） - 2010 - 0（已缴税）

所以我的问题是：

由于“UnitPrice”列是别名，我无法得到它的总和！我该怎么办？ 我想有psedu代码或关于如何做的想法...

如果你想查看我的查询，这里是（警告它看起来很吓人，写得很糟糕，需要稍后调整）：

SELECT     CustomerInvoice.cuInvoiceID, CustomerQuote.PONumber, CustomerInvoice.dueDate, 
           CASE
                 WHEN (SELECT isTaxPaid FROM SupplierQuoteProducts WHERE productID = CustomerQuoteProducts.ProductID) = 1 AND CustomerQuoteProducts.qty > 0 AND CustomerQuoteProducts.isTaxPaid > 0 THEN SUM(((CustomerQuoteProducts.unitPrice * 1.15) * 1.15) * CustomerQuoteProducts.qty)
                 WHEN (SELECT isTaxPaid FROM SupplierQuoteProducts WHERE productID = CustomerQuoteProducts.ProductID) = 1 AND CustomerQuoteProducts.qty <= 0 AND CustomerQuoteProducts.isTaxPaid > 0 THEN SUM((CustomerQuoteProducts.unitPrice * 1.15) * 1.15)

您可以在原件周围放置另一个查询以生成总和：

SELECT x.cuInvoiceID, x.PONumber, x.DueDate, sum(x.TotalPrice), x.trackingNumber, x.Year, x.isTaxPaid
    FROM (<YourOriginalQuery>) x
    GROUP BY x.cuInvoiceID, x.PONumber, x.DueDate, x.trackingNumber, x.Year, x.isTaxPaid

只需注意它，但是如果你将整个select语句放入FROM子句，那么你可以在别名中求和：

SELECT (Going to have to include the fields here and group by them), SUM(TotalPrice) FROM
SELECT    CustomerInvoice.cuInvoiceID, CustomerQuote.PONumber, CustomerInvoice.dueDate, 
           CASE
                 WHEN (SELECT isTaxPaid FROM SupplierQuoteProducts WHERE productID = CustomerQuoteProducts.ProductID) = 1 AND CustomerQuoteProducts.qty > 0 AND CustomerQuoteProducts.isTaxPaid > 0 THEN SUM(((CustomerQuoteProducts.unitPrice * 1.15) * 1.15) * CustomerQuoteProducts.qty)
                 WHEN (SELECT isTaxPaid FROM SupplierQuoteProducts WHERE productID = CustomerQuoteProducts.ProductID) = 1 AND CustomerQuoteProducts.qty <= 0 AND CustomerQuoteProducts.isTaxPaid > 0 THEN SUM((CustomerQuoteProducts.unitPrice * 1.15) * 1.15)
                 WHEN (SELECT isTaxPaid FROM SupplierQuoteProducts WHERE productID = CustomerQuoteProducts.ProductID) = 0 AND CustomerQuoteProducts.qty > 0 AND CustomerQuoteProducts.isTaxPaid > 0 THEN SUM((CustomerQuoteProducts.unitPrice * CustomerQuoteProducts.qty) * 1.15) 
                 WHEN (SELECT isTaxPaid FROM SupplierQuoteProducts WHERE productID = CustomerQuoteProducts.ProductID) = 0 AND CustomerQuoteProducts.qty <= 0 AND CustomerQuoteProducts.isTaxPaid > 0 THEN SUM(CustomerQuoteProducts.unitPrice * 1.15)
                 WHEN (SELECT Count(isTaxPaid) FROM SupplierQuoteProducts WHERE productID = CustomerQuoteProducts.ProductID) = 0 AND CustomerQuoteProducts.qty > 0 AND CustomerQuoteProducts.isTaxPaid > 0 THEN SUM((CustomerQuoteProducts.unitPrice * 1.15) * CustomerQuoteProducts.qty)

GROUP BY (all fields in the select except total price).
