[CMT8.4.1.1203]Cannot support migrate sub partition from oracle to cubrid.

When there is table which has subpartition, cannot migrate to CUBRID.

CREATE TABLE part_range_hash(
s_productid NUMBER,
s_saledate DATE,
s_custid NUMBER,
s_totalprice NUMBER)
PARTITION BY RANGE (s_saledate)
SUBPARTITION BY HASH (s_productid) SUBPARTITIONS 8
(
PARTITION sal99q1 VALUES LESS THAN (TO_DATE('02/01/2012','DD/MM/YYYY')),
PARTITION sal99q2 VALUES LESS THAN (TO_DATE('02/02/2012','DD/MM/YYYY')),
PARTITION sal99q3 VALUES LESS THAN (TO_DATE('02/03/2012','DD/MM/YYYY')),
PARTITION sal99q4 VALUES LESS THAN (TO_DATE('02/04/2012','DD/MM/YYYY')));
