我想展示每日库存 - 每日销售!!但我不知道该怎么做！
我试过这个方法 但是当加入库存时，销售表中缺少一些数据。
SELECT StoreName ,p.Date as Date
,p.ProductBarCode as ProductBarCode ,isnull(i.productqty-(select ProductQty as runningsum from #Stock st where st.date<=i.date and st.storeno=i.storeno and st.ProductBarCode = i.ProductBarCode ),i.productqty) as ProductQty
From #inventory i
LEFT JOIN Store S ON S.StoreNo = i.StoreNo
Left JOIN #Stock st ON st.StoreNo = i.StoreNo and st.ProductBarCode = i.ProductBarCode and st.Date = i.Date
