Mark : That is correct.
This is my scenary 1
At first time, the data is loaded without DELETE_DATE column filled.
Then, this column will be populated according the time passing.
The idea is keep partition by YEAR and subpartition by MONTH of the
DELETE_DATE column.
I have another scenary , where I would like to consider a mix of 2 columns
: INSERT_DATE and DELETE_DATE.
The column INSERT_DATE is always filled.
When I have the DELETE_DATE equal NULL I need to considerar all lines of
the table. In this situation, I would like a partition by YEAR and
subpartition by MONTH of the INSERT_DATE.
When the column DELETE_DATE != NULL I need to consider only lines that are
in the interval. The interval can be 6,12, 18 , 24 ... months before a
choosen date (MM-YYYY).
In both cases the query restriction clause must retrieve :
--> all lines that compose the list of data in the period (MM-YYYY - number
of months).

It appears that your plan is to have every new insertion in one partition
(forever) and then to move each row to a year-month partition when the row
gets an actual "delete_date."
Is that correct?
(Whether or not this is a useful strategy compared to things like
occasional copy-keep and partition exchange, I want to be sure I understand
your plan before I offer further advice.)

Thanks Cherif and Pavan for ansewring.
Now , I have another doubt.
I would like to create a partition by year and and for each year by month.
In the last example I used INTERVAL.
I have the code below.
Is there a way to create the partition structure without hard code the
year, as :

Hi Eriovaldo,
You can try to use virtual column as below.
CREATE TABLE DATA_LOAD_INT
( data_id NUMBER(6),
source_id NUMBER,
insert_date DATE,
delete_date DATE,
data_size NUMBER,
state VARCHAR2(20),
sys_current_date DATE DEFAULT SYSDATE,
year_delete_date NUMBER GENERATED ALWAYS AS
(TO_NUMBER(TO_CHAR(delete_date,'YYYY'))) VIRTUAL,
mm_delete_date NUMBER GENERATED ALWAYS AS
(TO_NUMBER(TO_CHAR(delete_date,'MM'))) VIRTUAL,
delete_date_part date GENERATED always as (
NVL(delete_date,TO_DATE('01-01-1900', 'DD-MM-YYYY'))) VIRTUAL
)
PARTITION BY RANGE (delete_date_part)
INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))
( PARTITION p0 VALUES LESS THAN (TO_DATE('01-01-1900', 'DD-MM-YYYY'))
)
enable row movement
;
Thanks,
Cherif.

Hi Eriovaldo,
If you refer to oracle documentation, it clearly says.conveys the
restrictions that "NULL" value are not allowed
For INTERVAL Clause
"You cannot specify NULL values for the partitioning key column."
Try to use some default value for that column, it may resolve issue.
- Thanks

Hello,
I have the code below and it is not working right, when I insert data.
I got the error message: ORA-14300: partitioning key maps to a partition
outside maximum permitted number of partitions
the insert has a null in the column delete_date.
Is there a way to define the partition using interval with NULL ?
