Hi all,
I have a table cartao with 200000 rows
How can I do to the query bellow read only some partitions
and not to do a FTS?
select * from
( select distinct card0_.pan as pan0_, cardstatus1_.id_cartao_status as id_carta1_1_
from cartao card0_, cartao_status cardstatus1_
where card0_.id_cartao_status=cardstatus1_.id_cartao_status(+)
and ((card0_.id_cartao_tipo=1 ))
order by card0_.pan )
where rownum <= 10
Is there a way to this?
Is there a way to reduce I/O for this case.?
