ALTER TABLE...DROP PARTITION v12

Use the ALTER TABLE… DROP PARTITION command to delete a partition definition, and the data stored in that partition. The syntax is:

ALTER TABLE <table_name> DROP PARTITION <partition_name>;

Parameters

table_name

The name (optionally schema-qualified) of the partitioned table.

partition_name

The name of the partition to be deleted.

Description

The ALTER TABLE… DROP PARTITION command deletes a partition and any data stored on that partition. The ALTER TABLE… DROP PARTITION command can drop partitions of a LIST or RANGE partitioned table; please note that this command does not work on a HASH partitioned table. When you delete a partition, any subpartitions (of that partition) are deleted as well.

To use the DROP PARTITION clause, you must be the owner of the partitioning root, a member of a group that owns the table, or have database superuser or administrative privileges.
