How do I alter my existing table to create a range partition in Oracle

Question

I have existing table which has 10 years of data (I have taken dump).

I would like to Range partition the existing table on one date key column within the table.

Beacuse your table non-partitioned you have two options:

1. Export data, drop table, create new patitioned table, import data.
2. Use split then exchange partition method. https://oracle-base.com/articles/misc/partitioning-an-existing-table-using-exchange-partition

Also, if you want new partition per month read about SET INTERVAL. For example:

CREATE TABLE tst
   (col_date DATE)
 PARTITION BY RANGE (col_date) INTERVAL (NUMTOYMINTERVAL(1, 'MONTH'))
(PARTITION col_date_min VALUES LESS THAN (TO_DATE('2010-01-01', 'YYYY-MM-DD')));
