It helps if you provide your data in a re-usable format , such as this:
with data(ParentItem,ChildItem,Qty)
as
(
select '2338-87468-00', '62338-77961-20', '45.333' union all
select '2338-87468-00', '62338-77961-18', '45.333' union all
select '2338-87468-00', '62338-84683-21', '45.333' union all
select '2338-87468-00', '62338-84683-18', '46' union all
select '2338-87468-00', '62338-87135-01', '46' union all
select '2338-87468-00', '62338-87135-00', '45'
),
-- Here is the query you need
RowNumbered(ParentItem,ChildItem,Qty,Rn) as
(
select *,row_number() over(partition by ParentItem order by Qty desc,ChildItem desc) as Rn
from data
)
select ParentItem,ChildItem,Qty
from RowNumbered
where Rn=1
I have done it for you because you are new here 🙂
