Interval partitioning. How to choose partition name

Question

Hi all,
Is there any wat to choose partition name when new partitions are created?
I mean insted of "SYS_P101" something like CUSTOMRES_P_256 where 256 is the new value that caused the creation of the partition.
The reason is that before running a long process I need to gather statistics on the partition based on that number
Thanks in advance,

You can rename a partition with your preferred naming convention:
alter table CUSTOMER rename partition SYS_P101 to CUSTOMRES_P_256;But first you need to know the name of the partition. One thing I have used in cases when an interval partition has not been created yet is to insert a record with the new partition key value so that the interval partition is created, then get the partition name and then roll back the insert. This way you know the partition name in advance of any data loading.
You can of course query dba_tab_partitions and look at the high_value column to select the correct partition. However, I prefer the following method of getting the partition name. It gives you the name of the partition for a row in a table. This is also useful for existing data (not just new partitions) if you ever need to find the partition where a certain row lives.
select subobject_name
into v_partition
from ALL_OBJECTS
where OWNER = 'SCHEMA_OWNER'
AND data_object_id in (select dbms_rowid.rowid_object(rowid)
                                 from FACT_TABLE
                                 where PARTITION_KEY_COL = MY_VALUE
                                 and rownum = 1);You can then use the partition name to load your facts, gather statistics, or rename the partition.
