Problem defining partition for storing value 0 with new data

Question

Hi forumers,
I've a problem with partitioning and need some advices.
I've a table that will be partitioned by column Process_N which have values from 0 to 50000:
Process_N between 1 and 29999 represents old data;
Process_N >= 30000 represents new data;
Process_N = 0 means the row is not processed yet and so these value represents new data too.
Can I have a partition for old values (from 1 to 29999) and another partition to store new values (0 + values >= 30000) ? Hou can I define that ?
Thank you in advance.
Best Regards,
Helena

Helena,
What's your oracle version? I think it will be better to create 3 partitions usign RANGE partitions (< 1, 2-29999, >=30000 <=50000). Is there a specific reason you want to include 0 and values greater than 29000 in one partition? What the significant difference between 0 and 30000 specially as both represent new data?
CREATE TABLE my_part_table (
   process_n NUMBER NULL,
   my_data VARCHAR2 (1 BYTE) NULL,
   my_other_data VARCHAR2 (30 BYTE) NULL,
   data_state NUMBER NULL
TABLESPACE test_data
PARTITION BY RANGE (process_n)
   (PARTITION partition_0
       VALUES LESS THAN (1)
       TABLESPACE test_data,
   PARTITION partition_2_29999
      VALUES LESS THAN (30000)
      TABLESPACE test_data,
   PARTITION partition_30000
      VALUES LESS THAN (50001)
      TABLESPACE test_data);Regards
