使用0 SQL / Access填充不存在的数据

Question

请参阅以下有关我的问题的说明。我有2张桌子。

SELECT LocationsOFproducts.[Bay no]
    ,LocationsOFproducts.[Product Code]
    ,LocationsOFproducts.LocationQTY
    ,SumDatahistoryQuery.SumOfQTY
    ,([LocationQTY]) + ([SumOfQTY]) AS TOTALQTY
FROM LocationsOFproducts
INNER JOIN SumDatahistoryQuery ON (LocationsOFproducts.[Product Code] = SumDatahistoryQuery.[Product Code])
    AND (LocationsOFproducts.[Bay no] = SumDatahistoryQuery.[Bay no])
    AND (LocationsOFproducts.[Product Code] = SumDatahistoryQuery.[Product Code])
GROUP BY LocationsOFproducts.[Bay no]
    ,LocationsOFproducts.[Product Code]
    ,LocationsOFproducts.LocationQTY
    ,SumDatahistoryQuery.SumOfQTY
    ,([LocationQTY]) + ([SumOfQTY])
ORDER BY LocationsOFproducts.[Product Code];

QUERY2: TOTAL QTY - Counting how many products left in some location after stock movement

SQL代码：

~/.ssh/authorized_keys

结果：

我希望结果有点不同。 我的查询应检查Datahistory表中的Bay no，产品代码和QTY是否还有更多值，如果不是我想用LocationOfproducts表中的数据填充该空间，并在SumOfQTY字段填写那些 值为0以在TOTALQTY列中进行求和。
请看下面我需要得到的内容：

谁能知道如何编写正确的查询？
