Как я могу использовать статистическую функцию SUM для столбца псевдонимов?

Question

Идентификатор счета-фактуры, номер заказа на поставку и срок платежа отображаются в двух экземплярах.

TotalPrice является псевдонимом (это должна быть цена за единицу, общая цена является ошибкой, поэтому предположите, что цена за единицу не общая цена)

TotalShippingPrice показывает цену доставки, которая была связана с InvoiceID / PONumber, для каждого invoiceID / PONumber будет одна цена доставки.То же правило применяется к отслеживающему номеру.

Год показывает, в каком году был отправлен этот счет (не беспокойтесь об этом).

isTaxPaid показывает, был ли уплачен налог в цене за единицу или нет (донне беспокойтесь об этом)

Мой запрос:

Мне нужно иметь дубликат удаления invoiceID и иметь сумму цены за единицу для каждого счета, поэтому должна быть только одна запись каждогоinvoiceID / PONumber с суммой цен за единицу.

Например:

30463 - 903315 - независимо от срока оплаты - 368 (92 + 276) - ----- (trackingNumber) - 2010 -0 (налог уплачен)

Итак, мой вопрос:

Поскольку столбец «UnitPrice» является псевдонимом, я не могу получить его сумму!Что я должен делать?Я хотел бы иметь псевдокод или идею о том, как это сделать ...

Если вы хотите увидеть мой запрос, вот он (предупреждение выглядит страшно и ужасно написано,позже надо настроить):

SELECT     CustomerInvoice.cuInvoiceID, CustomerQuote.PONumber, CustomerInvoice.dueDate,

Answer 1

Вы можете разместить другой запрос вокруг вашего оригинала, чтобы получить сумму:

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

Просто попытка, но если вы поместите весь оператор select в предложение FROM, вы можете суммировать по псевдониму:

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).
