You can drop, rename, partition, unpartition, merge, split, and move table partitions, with the following restrictions:
| Operation | Restriction | 
|---|---|
| Drop | You cannot drop a partition key column or the last partition of a partitioned table. | 
| Rename | N/A | 
| Partition an unpartitioned table | N/A | 
| 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.
