或者直接写sql语句

select * from (Select  产品SKU,sum(quantity) As [销量数量],sum([product sales]) As [销售额],sum(total) As [收到的款] From {SKU列表} Inner JOIN {两个月销量} ON {两个月销量}.[sku] = {SKU列表}.[产品SKU] Group By 产品SKU) as a left join (Select  产品SKU,产品ASIN,sum([estimated-monthly-storage-fee]) As [仓储费] From {SKU列表} Inner JOIN {仓储费} ON {仓储费}.[asin] = {SKU列表}.[产品ASIN] Group By 产品SKU,产品ASIN) as b on a.产品SKU = b.产品SKU
