Query optimizer using implied predicates

Renato Barrera, +4 more

- 18 Mar 2004

TL;DR: Improved query optimizer using implied predicates as mentioned in this paper facilitates allowing a query optimizing component to introduce extra predicates that facilitate the following: render the same results as the original query; are used as dictated by rules passed to the optimizing component; are considered as cost-based alternatives, and discarded if not useful; are tied to index utilization; and can consider both standard and multi-valued indices.
