Use the ALTER TABLE ADD PARTITION statement to add a new partition to the "high" end (the point after the last existing partition). To add a partition at the beginning or in the middle of a table, use the SPLIT PARTITION clause.
Example: HASH/RANGE PARTITIONS num... You can extend the PARTITION BY HASH clause to include SUBPARTITION BY either RANGE | LIST | HASH to create subpartitions in a HASH partitioned table. This example creates a table sales that's hash partitioned by part_no and subpartitioned using a range by dept_no .
To create a composite partitioned table, you start by using the PARTITION BY RANGE | LIST clause of a CREATE TABLE statement. Next, you specify a SUBPARTITION BY RANGE | LIST | HASH clause that follows similar syntax and rules as the PARTITION BY RANGE | LIST | HASH clause.
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION Cause: The corresponding columns in the tables specified in the ALTER TABLE EXCHANGE PARTITION are of different type or size Action: Ensure that the two tables have the same number of columns with the same type and size.
You cannot explicitly add a partition to an interval-partitioned table. The database automatically creates a partition for an interval when data for that interval is inserted.
You must specify at least one range partition using the PARTITION clause. The range partitioning key value determines the high value of the range partitions, which is called the transition point, and the database automatically creates interval partitions for data beyond that transition point.
So when we drop partitions we MUST ensure there is at least one remaining range partition. I normally create such range partition for the range that can never have any rows(e.g. VALUES LESS THAN(DATE '1-1-1')) This way all table data ends up in partitions I can drop.
You cannot explicitly drop a partition from a local index. Instead, local index partitions are dropped only when you drop a partition from the underlying table.
/ Drop the table named users / DROP TABLE users; / Drop the index called nameIndex on the table users / DROP INDEX IF EXISTS nameIndex ON users; You can drop an MR Table using the DROP statement in the same manner as you drop any other Oracle NoSQL Database table.
Delete a partition to remove the definition from the GUI partitioning list. You can only delete a partition if it contains no storage cells or drive bays. Move all storage cells and drive bays to another partition.
