我正在尝试根据以下方案计算Open列。

  1. 对于唯一销售订单+ sales_order_item，如果Billed_Item为NULL，则为Open = Order_Quantity。
  2. 如果Billed_Item不为null，则Open = Order_Quantity - Billed_Quantity直到该唯一的Billed_Quantity之和 sales_order + sales_order_item等于Order_Quantity。一旦 总和（Billed_Quantity为唯一sales_order + sales_order_item）= 对于所有sales_order + sales_order_item，Order_Quantity，然后Open变为= 0。

  3. 作为参考，请查看1209549436,1261171592以获取结果和预期结果表。看看1209549436如何将所有Open标记为0，因为billed_qty = order_quantity的总和但是对于1261171592它是订单 - 因为订单未完成而开票。奇怪的是啊!!

  4. 如果还不够，我必须创建一个视图。

    5. 我的当前查询

    SELECT
so.sales_order AS 'Sales_Order',
li.so_item 'Sales_Order_Item',
li.order_quantity AS 'Order_Quantity',
IF(bi.bill_item IS NULL, li.order_quantity, li.order_quantity - bi.bill_qty) AS Open,
li.so_net_price AS 'Sales_Order_Net_Price',
(li.order_quantity * li.so_net_price) AS 'Sales_Order_Net_Value',
bi.bill_item AS 'Billed_Item',
bi.bill_qty AS 'Billed_Quantity',
bi.bill_doc_date AS 'Billed_Document_Date'
FROM sap_sales_order so
LEFT JOIN sap_so_line_item li
ON so.sales_order = li.sales_order
LEFT JOIN sap_billing bi
ON so.sales_order = bi.sales_order
AND (li.so_item = bi.bill_item or bi.bill_item = 0);

    结果

2 个答案:

答案 0 :(得分：1)

您的if语句对于您尝试执行的操作不正确：

IF（bi.bill_item IS NULL，li.order_quantity，li.order_quantity - bi.bill_qty）

这意味着： 如果bill_item为null - 设置为order_quantity 否则设置为order_quantity - bill_qty

您需要一个子选择语句来评估跨越具有相同order_num的所有行的当前行的bill_qty的总和。

例如：

select
li.order_quantity - 
(select(sum(innerli.bill_qty) FROM sap_sales_order innerso
LEFT JOIN sap_so_line_item innerli
ON innerso.sales_order = innerli.sales_order
LEFT JOIN sap_billing innerbi
ON innerso.sales_order = innerbi.sales_order
AND (innerli.so_item = innerbi.bill_item or innerbi.bill_item = 0) 
and innerso.sales_order = so.sales_order)  //IMPORTANT LINE TO TIE THE SUB SELECT TO THE MAIN

FROM sap_sales_order so
LEFT JOIN sap_so_line_item li
ON so.sales_order = li.sales_order
LEFT JOIN sap_billing bi
ON so.sales_order = bi.sales_order
AND (li.so_item = bi.bill_item or bi.bill_item = 0);

将加入当前查询的派生表与按 Sales_Order 和 Sales_Order_Item 分组的聚合查询一起考虑。然后在外部查询中再次运行条件IF逻辑以计算打开：

SELECT unit.Sales_Order, unit.Sales_Order_Item, unit.Order_Quantity, 
       IF(unit.Order_Quantity = agg.Sum_Bill_Quantity, 0, unit.Open) AS 'Open', 
       unit.Sales_Order_Net_Price, unit.Sales_Order_Net_Value, unit.Billed_Item, 
       unit.Billed_Quantity, unit.Billed_Document_Date
FROM

    (SELECT so.sales_order AS 'Sales_Order',
            li.so_item AS 'Sales_Order_Item',
            li.order_quantity AS 'Order_Quantity',
            IF(bi.bill_item IS NULL, li.order_quantity,
            li.order_quantity - bi.bill_qty) AS Open,
            li.so_net_price AS 'Sales_Order_Net_Price',
            (li.order_quantity * li.so_net_price) AS 'Sales_Order_Net_Value',
            bi.bill_item AS 'Billed_Item',
            bi.bill_qty AS 'Billed_Quantity',
            bi.bill_doc_date AS 'Billed_Document_Date'
    FROM sap_sales_order so
    LEFT JOIN sap_so_line_item li
    ON so.sales_order = li.sales_order
    LEFT JOIN sap_billing bi
    ON so.sales_order = bi.sales_order
    AND (li.so_item = bi.bill_item or bi.bill_item = 0)
   ) As unit

INNER JOIN

   (SELECT so.sales_order AS 'Sales_Order', 
           li.so_item AS 'Sales_Order_Item', 
           SUM(bi.bill_qty) AS Sum_Bill_Quantity 
    FROM sap_sales_order so
    LEFT JOIN sap_so_line_item li
    ON so.sales_order = li.sales_order
    LEFT JOIN sap_billing bi
    ON so.sales_order = bi.sales_order
    AND (li.so_item = bi.bill_item or bi.bill_item = 0)
    GROUP BY so.sales_order, 
             li.so_item
   ) As agg

ON unit.Sales_Order = agg.Sales_Order 
AND unit.Sales_Order_Item = agg.Sales_Order_Item
ORDER BY unit.Sales_Order, unit.Sales_Order_Item;

要创建视图，请使用CREATE VIEW view_name AS select_statement。
