摘要： Techniques are provided for processing a query, including receiving the query, where the query specifies certain operations to be performed, including (a) a first set of one or more operations that are to be performed on a markup language data source and (b) a second set of one or more operations that are to be performed on a second data source. Then it is determined that a first server that manages the markup language data source is capable of performing the first set of operations. A request is sent to the first server to perform the first set of operations. A response is received, where the response contains results of performing the first set of operations on the markup language data source. Finally, results are generated for the query based at least in part on the results of performing the first set of operations.

摘要： Object-relational database systems process XML values in a way that preserves node identities of nodes in the XML values and perform node-id based operations more efficiently or even in circumstances where such operations were not performed. An object-relational database system represents an XML value as a serialized stream of bytes, herein referred to as a serialized image. A serialized image may represent an XML value of the XMLType that is stored and/or generated by an object-relational database system. The serialized image contains one or more node identifiers that identify nodes within the XML value. The serialized image may also contain a pointer to an in-memory representation of the XML value, allowing the in-memory representation to be accessed via the pointer without having re-create the in-memory representation.
摘要翻译：对象关系数据库系统以保持XML值中节点的身份标识并更有效地执行基于节点ID的操作的方式处理XML值，甚至在不执行此类操作的情况下处理XML值。对象关系数据库系统将XML值表示为串行字节流，这里称为序列化图像。序列化图像可以表示由对象关系数据库系统存储和/或生成的XMLType的XML值。序列化图像包含一个或多个标识XML值中的节点的节点标识符。序列化图像还可以包含指向XML值的内存中表示的指针，允许通过指针访问内存中的表示，而不重新创建内存中的表示。

摘要： A method and apparatus for rewriting a database command containing an embedded XML expression such that the rewritten database command recites a text function, in lieu of the embedded XML expression, is provided. Advantageously, a DBMS may take advantage of the efficiencies in storing XML data within the database, while avoiding the generation of unnecessary XML elements in processing the query when the XML elements contribute nothing to the outcome of the query. Cost-base or rule-based analysis may be performed to determine how to rewrite a received database command. The database server may functionally evaluate the text function or may use an index defined on a column of the database. The text function may function as a primary filter or may reference a column upon which an index is defined, wherein the index operates at the same or higher level than a column being referenced in the embedded XML expression.
摘要翻译：提供一种用于重写包含嵌入式XML表达式的数据库命令的方法和装置，使得重写的数据库命令背景文本功能代替嵌入的XML表达。有利地，DBMS可以利用在数据库中存储XML数据的效率，同时避免在XML元素对查询的结果没有贡献时在处理查询时生成不必要的XML元素。可以执行基于成本或基于规则的分析来确定如何重写接收到的数据库命令。数据库服务器可以在功能上评估文本功能，或者可以使用在数据库的列上定义的索引。文本函数可以用作主过滤器，或者可以引用定义索引的列，其中索引在与嵌入式XML表达式中引用的列相同或更高的级别上操作。

摘要： To associate XML data objects (“child objects”), stored in rows of relational or object-relational tables, with the appropriate XML data objects (“parent objects”) from which the child objects descend, tables that contain child objects (“out-of-line” tables) are constructed with an additional column. In one embodiment, this column stores values that identify the root objects, in the appropriate table, from which the respective child objects descend. Hence, the root object from which any given object descends is traceable by following the respective value back to the corresponding root object. In one embodiment, this column stores values that identify the complete XML hierarchical path, through multiple tables, back to the root object from which the respective child objects descend. Consequently, XML query language queries against XML documents stored in such tables can be rewritten as SQL queries against the data in the tables, even in the presence of cyclic constructs.

摘要： A method for representing XML information is provided. A serialized image of XML information is generated. The serialized image comprises a collection of one or more serialized data values, where each particular serialized data value in the collection includes data associated with a particular serialized data value type of a plurality of serialized data value types. The serialized image may also comprise a first field that includes a first value, which indicates that the serialized image includes the collection of one or more serialized data values. In some embodiments, the method is performed at a database system that supports a native XML data type, wherein the XML information is one or more instances of the native XML data type.

摘要： Techniques for managing XML data associated with multiple execution units ensure that execution units are able to use XML data coming from other execution units. Such techniques are applicable when, but for the technique, an XML type value is produced in a particular form by one execution unit and is supposed to be consumed by another execution unit that is unable to process data in the particular form, and involves detecting that the foregoing situation exists and annotating information sent to an XML producer execution unit to cause the XML type value to be transformed into a canonical form that can be shared by all relevant execution units.

摘要： Techniques are described for executing queries that have XPath sections that specify unmappable paths. The techniques involve splitting the unmappable paths into (1) a mappable path fragment, and (2) an unmappable path fragment. After an unmappable path has been split into a mappable path fragment and an unmappable path fragment, the XPath section is replaced with a replacement XPath section. The replacement XPath section specifies two operations: a “mappable operation” that is based on the mappable path fragment, and an “unmappable operation” that is based on the unmappable path fragment. The portion of the replacement XPath section that specifies the mappable operation is rewritten to access underlying relational structures. Consequently, when the rewritten query is executed, a smaller amount of XML data needs to be materialized to evaluate the unmappable path fragment than would otherwise have been required to evaluate the original unmappable path.
摘要翻译：描述了执行具有指定不可映射路径的XPath节的查询的技术。这些技术涉及将不可映射的路径分解为（1）可映射路径片段，以及（2）不可映射的路径片段。将不可映射路径分解为可映射路径片段和不可映射路径片段后，XPath节将替换为替换的XPath节。替换XPath部分指定两个操作：基于可映射路径片段的“可映射操作”和基于不可映射路径片段的“不可映映操作”。替换XPath部分指定可映射操作的部分被重写为访问基础关系结构。因此，当执行重写的查询时，需要实现较少量的XML数据来评估不可映射的路径片段，而不是否则需要评估原始的不可映射路径。

摘要： Techniques for executing database commands include receiving a database command that includes an XML component operation that operates on an XML construct that is based on a first set of one or more relational database constructs. It is determined whether the XML component operation can be transformed to a relational database operation on a particular set of one or more relational database constructs of the first set, which does not involve the XML component operation. If it is determined that the XML component operation can be transformed, then the XML component operation is rewritten as a particular relational database operation that operates on the particular set and that does not involve the XML component operation. The particular relational database operation is evaluated. In another aspect, techniques include determining a primitive set of XML generation operations and replacing non-primitive XML generation operations with one or more operations from the primitive set.
