Suggest edits

This example adds a partition to the list-partitioned sales table. The table was created using the command:

CREATE TABLE sales
(
  dept_no     number,
  part_no     varchar2,
  country     varchar2(20),
  date        date,
  amount      number
)
PARTITION BY LIST(country)
(
  PARTITION europe VALUES('FRANCE', 'ITALY'),
  PARTITION asia VALUES('INDIA', 'PAKISTAN'),
  PARTITION americas VALUES('US', 'CANADA')
);

The table contains the three partitions americas, asia, and europe:

edb=# SELECT partition_name, high_value FROM ALL_TAB_PARTITIONS;
Output
 partition_name |     high_value
----------------+---------------------
 EUROPE         | 'FRANCE', 'ITALY'
 ASIA           | 'INDIA', 'PAKISTAN'
 AMERICAS       | 'US', 'CANADA'
(3 rows)

This command adds a partition named east_asia to the sales table:

ALTER TABLE sales ADD PARTITION east_asia
  VALUES ('CHINA', 'KOREA');

After the command is invoked, the table includes the east_asia partition:

edb=# SELECT partition_name, high_value FROM ALL_TAB_PARTITIONS;
Output
 partition_name |     high_value
----------------+---------------------
 EUROPE         | 'FRANCE', 'ITALY'
 ASIA           | 'INDIA', 'PAKISTAN'
 AMERICAS       | 'US', 'CANADA'
 EAST_ASIA      | 'CHINA', 'KOREA'
(4 rows)
