摘要
An improved method, system, and computer program product is disclosed that provides a hybrid approach to optimization which allows different subsets of data accessed by a query to be optimized with different access paths and execution approaches. Transformations may be performed to re-write the query, which restructures the query in a way that facilitates the hybrid optimization process. Multiple transformations may be interleaved to produce an efficient re-written query.
