QUESTION NO: 425

You need to create a partitioned table to store historical data and you issued the following command:
CREATE TABLE purchase_interval
PARTITION BY RANGE (time_id)
INTERVAL (NUMTOYMINTERVAL(1,’month’)) STORE IN (tbs1,tbs2,tbs3) (
PARTITION p1 VALUES LESS THAN(TO_DATE(‘1-1-2005’, ‘dd-mm-yyyy’)),
PARTITION p2 VALUES LESS THAN(TO_DATE(‘1-1-2007’, ‘dd-mm-yyyy’)))
AS
SELECT *
FROM purchases
WHERE time_id < TO_DATE(‘1-1-2007’,’dd-mm-yyyy’);
What is the outcome of the above command?
A. It returns an error because the range partitions P1 and P2 should be of the same range.
B. It creates two range partitions (P1, P2). Within each range partition, it creates monthwise subpartitions.
C.It creates two range partitions of varying range. For data beyond ‘1-1-2007,’ it creates partitions with a width of
one month each.
D. It returns an error because the number of tablespaces (TBS1,TBS2,TBS3)specified does not match the
number of range partitions (P1,P2) specified.
Answer: C
