    • In one embodiment, a database server registers one or more functions included in a user-defined index that includes one or more auxiliary properties. The one or more functions are operable to generate index entries of the user-defined index for the one or more auxiliary properties. The one or more auxiliary properties are different than, and in addition to, a primary property of the user-defined index that provides for evaluating a query operator. The database server receives a first statement that defines the user-defined index, where the first statement includes one or more parameters that define the one or more auxiliary properties. The database server invokes the one or more functions in response to the first statement, where the one or more functions when invoked generate and store the index entries of the user-defined index according to the one or more parameters that define the one or more auxiliary properties.
    • 在一个实施例中,数据库服务器注册包括在包括一个或多个辅助属性的用户定义索引中的一个或多个功能。 一个或多个功能可操作以生成用于一个或多个辅助属性的用户定义索引的索引条目。 一个或多个辅助属性不同于并且除了用于定义查询运算符的用户定义索引的主要属性之外。 数据库服务器接收定义用户定义的索引的第一个语句,其中第一个语句包含一个或多个定义一个或多个辅助属性的参数。 数据库服务器响应于第一语句来调用一个或多个函数,其中调用时一个或多个函数生成并根据定义一个或多个辅助的一个或多个参数来存储用户定义的索引的索引条目 属性。

    • A bicycle includes a rear wheel rotatably mounted on a bicycle frame for rolling on a ground surface, a support unit pivotably mounted on the bicycle frame, and a locking unit disposed to releasably retain the support unit in a traveling position. The support unit includes a pivoted end, a shank member which extends from the pivoted end, and an elongated rail member connected to the shank member. The rail member has a supporting surface such that in a suspending position, the supporting surface is rested on the ground surface to suspend the rear wheel from the ground surface, and that when the support unit is turned to the traveling position, the rail member is turned to have the supporting surface face upwardly to serve as a rear rack of the bicycle.

    • A heavy-pedaling bicycle includes a pedaling unit which is rotated to deliver a driving force to drive a rear wheel to roll on a ground surface, and a dragging mechanism which is disposed on at least one of stationary and rotary members to generate a dragging force which counteracts the driving force during the forward pedaling of the pedaling unit, and which is self-adjustably maintained to be smaller than the driving force so as to turn the forward pedaling movement into an evenly decelerated movement. The dragging mechanism may include one of a plurality of wind blades, magnetically attractive members, and spring-biased friction members to generate a respective one of a resisting force, a magnetically attractive force, and a frictional force to serve as the dragging force.
    • 重踏脚踏车包括蹬踏单元,其被旋转以传递驱动力以驱动后轮在地面上滚动;以及拖曳机构,其设置在静止和旋转构件中的至少一个上以产生拖曳力 其在踩踏单元的向前踏板期间抵消驱动力,并且其被自动调节地保持为小于驱动力,以将前踏板运动转换成均匀的减速运动。 牵引机构可以包括多个风叶片,磁性吸引构件中的一个以及弹簧偏置的摩擦构件,以产生用作拖拉力的抵抗力,磁力吸引力和摩擦力中的相应的一个。

    • Techniques are provided for searching within a collection of XML documents. A relational table in an XML index stores an entry for each node of a set of nodes in the collection. Each entry of the relational table stores an order key and a path identifier along with the atomized value of the node. An index on the atomized value provides a mechanism to perform a node-aware full-text search. Instead of storing the atomized value in the table, a virtual column may be created to represent, for each node, the atomized value of the node. Alternately, each entry of the relational table stores an order key and a path identifier along with, for simple nodes, the atomized value, and for complex nodes, a null value. For a complex node with a descendant text node, a separate entry is stored for the descendant text node in the relational table.
    • 提供了在XML文档集合内进行搜索的技术。 XML索引中的关系表存储集合中一组节点的每个节点的条目。 关系表的每个条目存储订单密钥和路径标识符以及节点的雾化值。 雾化值上的索引提供了执行节点感知全文搜索的机制。 不用在表中存储雾化值,而是可以创建一个虚拟列,以便为每个节点表示节点的雾化值。 或者,关系表的每个条目存储订单密钥和路径标识符,对于简单节点,存在雾化值,对于复杂节点存储空值。 对于具有后代文本节点的复杂节点,为关系表中的后代文本节点存储单独的条目。
