DELETE is supported for NoPI tables.
DELETE has the following rules and restrictions for NoPI tables:
- A constrained DELETE request must use a full-table scan on a NoPI table unless the table has a secondary or join index and the Optimizer selects an access path that uses the index. However, column-partition elimination and row-partition elimination may allow an operation that does not require a full-table scan.
- To be eligible for fastpath delete processing, a DELETE ALL or unconstrained DELETE request on a NoPI table must conform to the rules described in Fastpath Positioning Requirements. Deferred deletions for entire row partitions that are deleted reclaims space for any logically deleted data in that row partition.
