Doubts regarding partition table.

Question

hi friends,
i'm using oracle 10g (10.2.0.1) on windows server 2003
i've a table, contains more than 2 million records, and it is range partition with quarterly by year.
like values less than('01-05-2008')
values less than('01-09-2008')
selecting multiple partition in single query without union is not possible.
so i fire the query like.
select col1,col2,col3 from table where r_date between ('01-01-2008','25-06-2008');
i would like to know that with this query, it will scan full table or it will scan only those two partitions...?
thanks,

Answer 1

i did that..
when i fire the following query...
select /*+ first_rows(1000) */ col1,col2,col3
from table
where r_date between to_date('01-01-2008','dd-mm-yyyy') and to_date('01-03-2008','dd-mm-yyyy');
explain plan:
SELECT STATEMENT, GOAL = HINT: FIRST_ROWS               11     1001     50050     640279     0     1     161
PARTITION RANGE ITERATOR               11     1001     50050     640279     1     1     161
TABLE ACCESS FULL     DBO     KEY_HISTORY_PART     11     1001     50050     640279     2     1     161
it shows table access full and partition range iterator..
because of that i'm asking..
thanks..
