Deleting a Partition from a Partitioned Table

You can run ALTER TABLE DROP PARTITION to delete any partition from a range partitioned table, interval partitioned table, or list partitioned table.

For example, delete the partition date_202005 from the range partitioned table range_sales by specifying the partition name and update the global index. 
ALTER TABLE range_sales DROP PARTITION date_202005 UPDATE GLOBAL INDEX;
Alternatively, delete the partition corresponding to the partition value '2020-05-08' in the range partitioned table range_sales. Global indexes become invalid after this command is executed because the UPDATE GLOBAL INDEX clause is not used. 
ALTER TABLE range_sales DROP PARTITION FOR ('2020-05-08');
  • If a partitioned table has only one partition, the partition cannot be deleted by using the ALTER TABLE DROP PARTITION statement.
  • If the partitioned table is a hash partitioned table, partitions in the table cannot be deleted by using the ALTER TABLE DROP PARTITION statement.
