Question

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)

Answer 1

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

Answer 2

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)

                      )
           END AS "TotalShippingPrice",

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

如何在别名列上使用聚合函数SUM？
