摘要： A method, computer program product, and system for processing dynamic statements in a database system are provided. The method, computer program product, and system provide for calculating a first set of characteristics associated with a dynamic statement when the dynamic statement matches one of a plurality of dynamic statements previously processed by the system, comparing the first set of characteristics associated with the dynamic statement to a second set of characteristics associated with one of one or more access paths generated for the one previously processed dynamic statement, and utilizing the one access path to execute the dynamic statement when the comparison of the first set of characteristics to the second set of characteristics satisfies one or more predetermined criteria.
