聚合查询，提供不需要的结果

Question

我已经写了一个查询来提取所有未完成的延期交货，只显示可以履行的行（根据订单数量检查库存水平）。

我想将每个订单汇总成一行。

客户名称/订单ID /总和（未结数量）/总和（qtyToSend）/ sum（unitSell）

目前我的输出看起来像这样 - 如果有人可以提供任何指导或指出我正确的方向，我将不胜感激。

SELECT 
    c.cus_name,
    ol.orderLines_orderId,
    oh.orderHeader_status,
    ol.orderLines_stockRef,
    ol.orderLines_qtyOrdered,
    ol.orderlines_qtyInvoiced, 
    ol.orderLines_qtyOrdered - ol.orderlines_qtyInvoiced as qtyOutstanding,
    (CASE
        WHEN ol.orderLines_qtyOrdered - ol.orderlines_qtyInvoiced > pr.products_instock THEN pr.products_instock
        ELSE (ol.orderLines_qtyOrdered - ol.orderlines_qtyInvoiced)
    END) AS qtyToSend,
    pr.products_instock,
    FORMAT(ol.orderLines_totalSell/ol.orderLines_qtyOrdered,2) as unitSell
FROM
    cus c
        JOIN
    orderheader oh ON oh.orderHeader_customer = c.cus_id
        JOIN
    orderlines ol ON ol.orderLines_orderId = oh.orderHeader_id
        JOIN
    products pr ON ol.orderlines_stockref = pr.products_reference
WHERE
    ol.orderLines_qtyOrdered <> ol.orderlines_qtyInvoiced
HAVING
    qtytosend > 0

我试过这样做，但订单的价值不正确。根据我对第1行（Emiliano's Gifts Bros）的计算，延期交货的总价值应为34.42英镑

SELECT 
    c.cus_name,
    ol.orderLines_orderId,
    sum(ol.orderLines_qtyOrdered - ol.orderlines_qtyInvoiced )as qtyOutstanding,
    sum((CASE
        WHEN ol.orderLines_qtyOrdered - ol.orderlines_qtyInvoiced > pr.products_instock THEN pr.products_instock
        ELSE (ol.orderLines_qtyOrdered - ol.orderlines_qtyInvoiced)
    END))AS qtyToSend,
    sum(FORMAT(ol.orderLines_totalSell/ol.orderLines_qtyOrdered,2)) as unitSell
FROM
    cus c
        JOIN
    orderheader oh ON oh.orderHeader_customer = c.cus_id
        JOIN
    orderlines ol ON ol.orderLines_orderId = oh.orderHeader_id
        JOIN
    products pr ON ol.orderlines_stockref = pr.products_reference
WHERE
    ol.orderLines_qtyOrdered <> ol.orderlines_qtyInvoiced
GROUP BY
    ol.orderLines_orderId
HAVING
    qtytosend > 0
