Because NoPI tables do not have a primary index, single-AMP primary index access is not available. The table must be accessed using a full-table scan, unless one on the following conditions is true:
- Table has a secondary or join index that the Optimizer can use for the access plan, or
- Column or row partition elimination can be applied for a column-partitioned table.
Secondary and join index access paths work the same for NoPI tables as for primary index tables.
