Question

我的查询

select distinct 
EnglishProductCategoryName,
sum(isnull(fic.SalesAmount,0))InternetSalesAmount,
sum(isnull(frs.SalesAmount,0))ResellerSalesAmount

 from dimproduct dp   join DimProductSubcategory dps on dp.ProductSubcategoryKey=dps.ProductSubcategoryKey
                     join DimProductCategory dpc on dpc.ProductCategoryKey=dps.ProductCategoryKey
                     left join FactInternetSales fic on fic.ProductKey=dp.ProductKey
                     left join FactResellerSales frs on frs.ProductKey= dp.ProductKey

        group by EnglishProductCategoryName

但是当我这样做

select sum(isnull(fis.SalesAmount,0))InternetSalesAmount from FactInternetSales 
select sum(isnull(frs.SalesAmount,0))resellerSalesAmount from FactResellerSales

比较整个英文产品类别名称的总和与互联网销售额的总和，代理商的销售额应该相同但不相同

将寻求帮助谢谢

检查是否缺少ProductSubcategory或ProductCategory

select distinct 
EnglishProductCategoryName,
sum(isnull(fic.SalesAmount,0))InternetSalesAmount,
sum(isnull(frs.SalesAmount,0))ResellerSalesAmount

 from dimproduct dp   left join DimProductSubcategory dps on dp.ProductSubcategoryKey=dps.ProductSubcategoryKey
                    left join DimProductCategory dpc on dpc.ProductCategoryKey=dps.ProductCategoryKey
                     left join FactInternetSales fic on fic.ProductKey=dp.ProductKey
                     left join FactResellerSales frs on frs.ProductKey= dp.ProductKey

        group by EnglishProductCategoryName
