摘要： Techniques for selective compression of database information are presented. Selective first portions of a field associated with a database table are identified along with metadata associated with the database table. The first portions and the metadata are then compressed by selecting one or more compression algorithms in response to compression capabilities associated with the algorithms.

摘要： An apparatus for providing shade to an individual is adjustable in three planes. In some embodiments, the shading apparatus include a primary shaft secured to a fixed base such as a pedestal seat. A height adjustable and telescoping secondary shaft is inserted concentrically into the primary shaft. A pivot joint assembly is secured to the secondary shaft, and a shading device is mounted to the pivot joint assembly. The pivot joint assembly allows for rotational, pivoting, and sliding adjustment in order to provide positional flexibility to the individual seeking shade.

摘要： A carrier of liquid is manually portable, thermally insulated, and pressurizable for dispensing the liquid, particularly cold or hot potable beverages such as beer, water, lemonade, sports drinks, tea, and the like. A container for holding the liquid can be pressurized by hand or other pump or by a gas cartridge, and the liquid flows when desired from the container through a tube and a dispensing valve mounted in the carrier wall. The carrier is thermally insulated to retain cold or heat in the liquid, and ice or hot briquettes can be placed about the container within the carrier walls to retain the desired temperature for a longer period. Handles and wheels can be mounted to the carrier to make the article more easily portable.

摘要： A method, apparatus, and article of manufacture for optimizing SQL queries in a relational database management system involving aggregate and grouping functions. A local aggregation operation is performed on one or more processors of a massively parallel processor (MPP) computer system, wherein rows of the table that are local to each processor are locally aggregated to create one or more aggregate result rows. The aggregate result rows created by each of the local aggregation operations are then re-distributed to one or more processors and coalesced into a global aggregate result row by a global aggregation operation.
摘要翻译： 一种在关系数据库管理系统中优化SQL查询的方法，装置和制品，涉及聚合和分组功能。 在大规模并行处理器（MPP）计算机系统的一个或多个处理器上执行本地聚合操作，其中本地对每个处理器进行本地表的行被本地聚合以创建一个或多个聚合结果行。 然后将由每个本地聚合操作创建的聚合结果行重新分配到一个或多个处理器，并通过全局聚合操作合并到全局聚合结果行。
