Abstract: A mechanism is provided for detecting and disregarding application specific nodes contained in shared XML documents. The techniques described involve determining one or more application specific nodes within XML documents and performing path expression evaluations of the XML documents as if the nodes are not present. In one embodiment, a mechanism is provided by which a user may specify the criterion that determine which subset of node in XML documents are to be ignored from path expression evaluations and evaluating a query that specifies a path operation based on a path and ignoring said identified nodes when evaluating said path operation.

Abstract translation: 提供了一种用于检测和忽略包含在共享XML文档中的应用程序特定节点的机制。 所描述的技术涉及确定XML文档内的一个或多个应用特定节点，并且如同节点不存在一样执行XML文档的路径表达式评估。 在一个实施例中，提供了一种机制，用户可以通过该机制指定确定XML文档中的节点的哪个子集将被从路径表达式评估中忽略的标准，并且基于路径评估指定路径操作的查询，并忽略所述标识的 节点在评估所述路径操作时。

Abstract: A method and apparatus for managing hierarchical relationships in a relational database system is provided. An “orderkey” data type, which is native within a relational database system, is disclosed. The orderkey type is designed to contain values that represent the position of an entity relative to the positions of other entities within a hierarchy. Such values represent hierarchical relationships between those entities. Values that are of the orderkey type have properties that allow hierarchy-oriented functions to be performed in an especially efficient manner. Database functions, which operate on and/or produce values that are of the orderkey type, are also disclosed. Such functions can be placed within SQL statements that a database server executes, for example. In response to executing SQL statements that contain such functions, the database server performs hierarchy-oriented operations in a highly efficient manner.
