Nope.

As I have duplicates I will need to use unique or distinct in the query..

I need not to take into account the exiting duplicates because the balance in the extraction is wrong due to this ID's duplicated

Any idea?

do you mean this?


select id,
sum(case when rn=1 then col_balance else 0 end) 
from 
(
select row_number() over (partition by id order by id) as rn,*
from table
)t
group by id
