Restrictions on DDL Operations on Partitions

You can drop, rename, partition, unpartition, merge, split, and move table partitions, with the following restrictions:




You cannot drop a partition key column or the last partition of a partitioned table.



Partition an unpartitioned table


Merge two adjacent partitions

Both partitions must reside in the same dbspace. No data movement is required.

Split a partition

All rows must belong to one of the two partitions after splitting. Split partition must be on same dbspace as original so that no data movement is required.

Move a partition to a new dbspace.

All rows of the partition are moved to data pages in the new dbspace. CREATE permission in the new dbspace is required.

Partitioned tables cannot participate in a join index.
