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.
With Oracle Partitioning, a single logical object in the database is subdivided into multiple smaller physical objects, so-called partitions. The knowledge about this physical partitioning enables the database to improve any application's performance, manageability, or availability.
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 can use the ALTER TABLE statement to modify a partitioned table after the table is created. Specifically, you can use the ADD PARTITION clause to add a new data partition to an existing partitioned table.
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.
Without partitioning, there is a maximum of 4 294 967 288 rows in a table, or a maximum size of 1.7 TB (where TB equals 1 099 511 627 776 bytes). A partitioned table, however, can have many partitions, with each partition being able to have the maximum table size.
To create and format a new partition (volume) Right-click an unallocated region on your hard disk, and then select New Simple Volume. In the New Simple Volume Wizard, select Next. Enter the size of the volume you want to create in megabytes (MB) or accept the maximum default size, and then select Next.
Range partitioning is a convenient method for partitioning historical data. The boundaries of range partitions define the ordering of the partitions in the tables or indexes. Interval partitioning is an extension to range partitioning in which, beyond a point in time, partitions are defined by an interval.
