oracle - How do I create a partitioned table without initial partitions? -

say, have following ddl:

create table partition_test_table (     id number(38,0) not null,     value varchar(255),     country_code varchar(2) not null,     creation_date date not null,     constraint pk_partition_test_table primary key (id) ) partition range ( creation_date ) subpartition list ( country_code ); 

this doesn't work because doesn't declare initial partitions. how create partitioned table without initial partitions? possible?

thanks.
