My table structure is something like this, I m new to partitions, need to add new partitions for table from March_2021 for few months, need correct syntax for this, I tried to google but not able to find example for adding partition with subpartition. Database 10g

Answer 1

Because you have a template, adding partitions is transparent to subpartitions:

alter table your_table add partition mon_mar_2012 values less than (3000);

(This will automaticaly creates subpartitions for the new partition).

EDIT: if you wouldn’t have had template, you should have create subpartitions manualy:

ALTER TABLE your_table MODIFY PARTITION partition
      ADD SUBPARTITION subpartition_name ...
