是否有SQL函数可以多次添加数据中出现的产品的总单位

我正在减少一些数据以便于阅读，它是由每笔交易输入的，但是我需要每个产品代码只有一行，而不是多行（销售单位和总英镑的总和）。我如何才能做到这一点，使我没有600000行，只有2500个产品代码

select [master code], [product code], [units sold]
  , [product weight] * [units sold] as 'Total Lbs per Product'
from [dbo].[sales_data_outgoing_master]
where [ship year] = 2019
order by [family code]

我得到了一个像照片中最上面那张桌子一样的答案，我想要一张像下面那张桌子一样的桌子。SQL中有这样做的代码吗

这就是你想要的吗

select [master code], [product code], SUM([units sold]) as [units sold]
    , SUM([product weight] * [units sold]) as 'Total Lbs per Product' 
    , [family code]
from [dbo].[sales_data_outgoing_master]
where [ship year] = 2019
GROUP BY [master code], [product code], [family code]
order by [family code]
