- Define a column_1_name for each column_name in the primary base table to be included in the single-table join index.
- To enhance join selectivity, define the primary index on a different column set than the primary base table, or define column partitioning.
- If the physical database design warrants, use:
- CREATE INDEX to create one or more NUSIs on the join index
- A WHERE clause to define a sparse join index
- A unique primary index for the join index
