Sql oracle中的Group by无法使用max

我在试图让我的团队在Oracle工作时遇到问题

我的剧本如下

Select
    DISTINCT dc.despatch_num as ShipmentReference,
    sh.delivery_name as Name,
    dc.address1 as DeliveryAddress1,
    dc.address2 as DeliveryAddress2,
    dc.address3 as City,
    dc.address5 as County,
    dc.POSTCODE as Postcode,
    dc.country_code as Country,
    sh.inv_contact_telephone_1 as TelephoneNumber,
    sh.inv_contact_email as email,
    ph.package_num as Numberofpackages,
    ph.package_id as PackageReference,
    ph.weight as PackageWeight,
    'Kilos' as WeightUnit,
    max(pro.length) as Length
from 
    sales_header sh
    left join customer cu on sh.customer_account = cu.customer_account
    left join sales_item si on sh.sales_document_num = si.sales_document_num
    left join customer_address ca on cu.customer_account = ca.customer_account
    left join additional_charge ac on sh.sales_document_num = ac.sales_document_num and sh.order_type = ac.order_type
    left join despatch_header dc on ac.despatch_num = dc.despatch_num
    left join package_header ph on dc.despatch_num = ph.despatch_num
    left join product pro on si.product_code = pro.product_code
WHERE sh.customer_name <> sh.Delivery_name and rownum <= 100 and dc.country_code ='FR';
group by DISTINCT dc.despatch_num,
    sh.delivery_name,
    dc.address1,
    dc.address2,
    dc.address3,
    dc.address5,
    dc.POSTCODE,

    sh.inv_contact_email,
    ph.package_num,

。另外，
SELECT DISTINCT
几乎从未与
groupby
一起使用。已删除它们，但仍收到相同的错误。同时删除第一个DISTINCT。因为您显示的是按分组的数据，所以它无论如何只会显示不同的值
'FR'删除
和
'Kilos'，
