Abstract

Query Optimization refers to the process of selecting an efficient plan to execute a given query from among the various ways available. Each of the alternatives available to the optimizer have an associated cost estimate. Usually, either all the components of a cost estimate are known at compile time or their values are assumed and taken as constant. Plans selected using such assumptions could prove to be sub-optimal if cost parameters change significantly between compile time and run time. &quot;Parametric Query Optimization&quot; attempts query optimization even where some of the factors involved in cost calculation are not known till the query is executed nor can they be accurately estimated.
