摘要： An update to a primary table is received. The primary table is read to determine the set of rows to be updated. The primary table is updated and XML objects stored in XML columns are overwritten according to the update. A pre-update node table comprising the nodes corresponding to the updated rows is created from an XML index table corresponding to the primary table. A post-update node table is created by shedding the updated XML objects. The post-update table and the pre-update table are merged according to their node identifiers. The resulting merged table can be inspected to determine which nodes have been, added, deleted, or updated. Based on this inspection, the necessary additions and deletions can be efficiently made to the XML index table.
摘要翻译：接收到主表的更新。读取主表以确定要更新的行集。更新主表，并根据更新覆盖存储在XML列中的XML对象。包括与更新的行相对应的节点的预更新节点表从与主表对应的XML索引表创建。通过删除更新的XML对象来创建更新后节点表。后更新表和更新前的表根据其节点标识符进行合并。可以检查产生的合并表以确定哪些节点已被添加，删除或更新。基于此检查，可以有效地对XML索引表进行必要的添加和删除。

摘要： An extensible markup language (XML) expression included in a query is parsed to yield an abstract syntax tree. The abstract syntax tree is then transformed into a unified tree including XML algebra operations. The unified tree is then converted into a relational tree including enhanced relational algebra operations. The relational tree is then forwarded to a query processor for optimization and execution of the query at the query processor.

摘要： Storing and querying XML data in a primary table or document utilizes an index of XML data and includes creating a primary table structure, creating a primary XML index commensurate with the primary table structure, populating the primary table and the primary XML index, and running a query on the XML data in a primary table by utilizing the XML index. The XML index can be implemented as a node table. The node table may have a B+-tree structure and be populated by shredding the XML values in the primary table. The XML data may be stored as binary large objects in an XML column of the primary table. Secondary XML indexes may be created to assist in the search and retrieval of XML data stored in the primary table. Both the primary XML index and the secondary XML index tables may be created using data definition language statements.
摘要翻译：在主表或文档中存储和查询XML数据使用XML数据索引，包括创建主表结构，创建与主表结构相称的主XML索引，填充主表和主XML索引，并运行通过利用XML索引对主表中的XML数据进行查询。 XML索引可以实现为节点表。节点表可以具有B + SUPERTree结构，并且通过对主表中的XML值进行粉碎来填充。 XML数据可以作为二进制大对象存储在主表的XML列中。可以创建辅助XML索引以帮助搜索和检索存储在主表中的XML数据。主XML索引和辅助XML索引表都可以使用数据定义语言语句创建。

摘要： Several embodiments of the present invention are directed to systems and methods for extending the UDT framework of an extended relational data store (ERDS) to include support for unordered collections (multisets) and ordered collection (lists). More specifically, several embodiments of the present invention use an UDT infrastructure, CLR generics, and a new UNNEST operator to create and utilize a special type abstraction for collections that is simultaneously a scalar and a relation. As a scalar, this collection type can be processed by all parts of the data store engine that understand scalars (including but not limited to the client stack) and, as a relation, this collection type is queriable like any other type of relation.

摘要： Detailed herein is a technology which, among other things, allows a search engine to utilize a user-defined relevance function. In one approach to the technology, a method of applying a user-defined relevance function is described. In this approach, a complex search query is decomposed into a simple operator. The simple operator is associated with the user-defined relevance function. A document which matches the search query is retrieved, and a rank is calculated for the document, using the user-defined relevance function.
