Abstract
In a database system that supports object name overloading, database query statements are compiled and cached as data structures so that object level privileges are correctly resolved. Database query statements stored in the cached data structures are utilized when appropriate and a new compilation is performed when an incorrect resolution would result. The data structures are stored in a predefined order to ensure that a deterministic search of the cache is efficiently performed.
