I have a large table as dataset. If there are 2 similar rows with same date and id then how do I get the row for which another column value is not null?

SELECT *, row_number() 
   over (partition by id order by date desc) rowNumber 
FROM table where rowNumber = 1;

Please try this query:

select * from table where (id, date) in 
(select id, date from table group by id, table having count(1) > 1) 
and value is not null;
