Q98. 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
