A control device and a control program for a walking assist apparatus set a desired lifting force to act on a user from a seat and distribute the desired lifting force to each leg link of the walking assist apparatus according to the ratios of treading forces of the legs of the user measured on the basis of outputs of force sensors so as to determine the share for each leg link. Then, an actuator of each leg link is controlled to generate a force for the determined share. Thus, a force required for the user to support himself / herself with his / her leg or legs on a floor can be reduced while using a reduced number of parts to be attached to each leg of the user. Moreover, an assist force for achieving such a reduced required force can be properly shared between the leg links associated with the legs of the user.

One embodiment of the present invention provides a system that optimizes the execution of a database query involving a target partitioned-database-object. During system operation, the database receives a query. If the query has a predicate that includes a partition-mapping function that uses the partitioning schema of a partitioned database-object and a list of columns from one or more tables to express a mapping of the list of column values to the partitions of the partitioned database-object, the system determines the compatibility of the partitioning schemas of the target partitioned-database-object and the partitioned database-object. Next, if the partitioning schemas are compatible, and if the list of columns is compatible with the partitioning keys of the target partitioned-database-object and the partitioned database-object, the system attempts to identify a subset of partitions in the target partitioned-database-object that satisfy the predicate. Finally, if a subset of partitions is successfully identified, the system performs the query only on the identified subset of partitions, and not on the other partitions, thereby optimizing the execution of the query by reducing the number of partitions that need to be accessed.
