动态库存缺少价值且没有销售
我有以下查询,
QryStockOnHand
SELECT QrySaleTot.Item, QrySaleTot.ProductID, [QryStockLevel].[Stock]-[QrySaleTot].[Quantity] AS StockOnHand
FROM QryStockLevel INNER JOIN QrySaleTot ON QryStockLevel.ProductID = QrySaleTot.ProductID;
QrySaleTot
SELECT TblProduct.Item, Sum(TblTotalSale.Size) AS Quantity, TblProduct.ProductID
FROM TblProduct INNER JOIN TblTotalSale ON TblProduct.[ProductID] = TblTotalSale.[ProductID]
GROUP BY TblProduct.Item, TblProduct.ProductID;
QryStockLevel
SELECT TblStock.ProductID, Sum(TblStock.StockLevel) AS Stock, TblProduct.Item
FROM TblStock INNER JOIN TblProduct ON TblStock.ProductID = TblProduct.ProductID
GROUP BY TblStock.ProductID, TblProduct.Item;
当我运行 QryStockonHand 并且没有销售任何产品时,该产品不会出现在查询结果中...

任何想法为什么...我猜这是一个空的东西,它将无销售视为不存在的事情,而不是零销售......知道我如何解决它吗?
谢谢萨姆
I have the following queries,
QryStockOnHand
SELECT QrySaleTot.Item, QrySaleTot.ProductID, [QryStockLevel].[Stock]-[QrySaleTot].[Quantity] AS StockOnHand
FROM QryStockLevel INNER JOIN QrySaleTot ON QryStockLevel.ProductID = QrySaleTot.ProductID;
QrySaleTot
SELECT TblProduct.Item, Sum(TblTotalSale.Size) AS Quantity, TblProduct.ProductID
FROM TblProduct INNER JOIN TblTotalSale ON TblProduct.[ProductID] = TblTotalSale.[ProductID]
GROUP BY TblProduct.Item, TblProduct.ProductID;
QryStockLevel
SELECT TblStock.ProductID, Sum(TblStock.StockLevel) AS Stock, TblProduct.Item
FROM TblStock INNER JOIN TblProduct ON TblStock.ProductID = TblProduct.ProductID
GROUP BY TblStock.ProductID, TblProduct.Item;
When I run the QryStockonHand and no sales of a product have been made then the porduct does not appear in the result of the query...

Any Idea why... I guess it is a null thing, where it is seeing the no sales as a non existent thing, instead of a zero sales.... any idea how i could fix it?
Thanks

使用左外连接而不是内连接,这将告诉它从连接上的左表中获取所有行,而不是内连接,后者仅返回在两个表中都有值的行。
我不知道 QryStockLevel 字段,但您的查询应该如下所示:
请注意,当 qrysaletot 没有行时,NZ 函数会处理数量上的空值。
Instead of an inner join, use a left outer join, which will tell it to grab all of the rows from the left hand table on the join, instead of an inner join, which returns only rows which have values in both tables.
I don't know the QryStockLevel fields, but your query should look something like this:
Note the NZ function to handle a null on the Quantity when qrysaletot does not have a row.
