Question

我有以下查询，它会调出某些位置的特定商品的数量。

SELECT l.region, l.Region_Description, s.store_code AS store, s.name, s.city, p.province_code, s.telephone,  b.store_code, b.product_code,  b.product_id,

    ELSE COALESCE(SUM(CONVERT(INT, b.bin_qty_stocks)),0)  END AS inv_avail

, (SELECT SKU FROM @ALT WHERE RN = 2) AS Alt2SKU
, COALESCE(SUM(CONVERT(INT, Alt2.bin_qty_stocks)),0) AS Alt2Qty

GROUP BY l.region, l.region_description, s.store_code, s.name, s.city, p.province_code, s.telephone
, b.store_code, b.product_code, b.product_id, c.Channel_Index

在此查询之前，我正在构建两个临时表@ALT和@BUCKET。在@ALT中，我正在为所提供的项目@inSKU存储备用项目代码。在@BUCKET中，我正在存储@ALT中所有项目的库存数量。

问题是，我在“inv”中获得了相乘的数量。如果有4个备用项目，则inv数量乘以4.我不明白为什么会发生这种情况，这就是为什么我要求一些帮助来识别这个问题。如果我注释掉Alt1Qty，Alt2Qty，Alt3Qty，Alt4Qty，Alt5Qty，Alt6Qty加入，我得到正确的结果。

请告知。

感谢。

更新：实际上有两个部分需要查看第1节：

COALESCE(SUM(CONVERT(INT, b.bin_qty_stocks)),0) AS inv
,  dbo.pp_fnGetHoldbackQuantity(c.Channel_Index - 1, b.product_id) AS web_hb
,  CASE WHEN b.store_code = '0010' THEN SUM(CONVERT(INT, b.bin_qty_stocks))  - dbo.pp_fnGetHoldbackQuantity(c.Channel_Index - 1, b.product_id) 
    ELSE COALESCE(SUM(CONVERT(INT, b.bin_qty_stocks)),0)  END AS inv_avail

Answer 1

在您完成的工作的基础上，一种方法是在您加入其他表之前对库存数量求和，这样库存计数就不能通过1：M连接到其他表来膨胀：

类似......（因为我没有你的表/数据，这是未经测试的）

也许使用窗口函数（再次未经测试）但我认为我必须在那里处理基于AND b.Bin_Code in ('STORE', 'VW', 'V') AND b.product_code = @inSKU的条件求和的情况所以我认为第一种方法更清晰。

现在这两个都基于这样的假设：如果您在@bucket表中生成“Sum totals”或者作为子查询生成了一个或多个alts，则生成的记录超过1个，因此只生成了1个记录对于每个store_Code_ID，这样你就不需要上面的任何一个，因为你已经修复了问题的根源。

Answer 2

我认为如果我们重新编写SQL以便它是理智的，那么问题（我们无法解决以确保只是查看这个sql）将会变得清晰。下面你会发现sql在功能上与你发布的SQL相同。

那么我们看到了什么？好吧altStuff是一个奇怪的结构，但它可能是你想要做的。如果有多行，它将无法工作 - 所以首先检查 - 运行该子查询并查看它是否只给你一行。如果它没有（我正在吃晚餐）那么这就是你的问题 - 你应该解决它。

注意：这与xQbert将在注释中使用OVER子句修复的问题相同，但在这种情况下，它更清晰，因为我已使用with子句将其破坏。

如果它不在altStuff中，那么pp_channel可能是问题，如果它有4行。如果做不到这一点，我不知道问题是什么。
