Select last 12 rows oracle

Question

I want to do a select in oracle that returns more or less 300 rows, but I just want the 12 last registries. Here is the query:

(SELECT * 
FROM series 
ORDER BY odata DESC) estatisticas 
WHERE ponteiro = 50 AND lotus = 30

Answer 1

Something along the lines of:

select * from 
    ( select estatisticas, rownum rn
        (SELECT *
        FROM series 
        ORDER BY odata DESC) estatisticas 
        WHERE ponteiro = 50 AND lotus = 30
    order by odata asc) where rownum <=12

Edit: updated it for your query, you want to sort it opposite of the inner query, ascending in your case, so you can get the last 12
