    摘要: Techniques are provided for determining whether an XML table index may be used when executing an XML query. An XML table index is defined with a row pattern expression and one or more column pattern expressions. In one technique, an index expression is generated for each row pattern expression-column pattern expression combination. An expression included in the XML query (“query expression”) is compared against one or more of the index expressions. In another technique, even if a query expression does not exactly match a row pattern expression, it is determined whether the query expression is equivalent to the row pattern expression. In another technique, even if a query expression does not exactly match and a row pattern expression, it is determined whether the query expression is “contained by” the row pattern expression.

    摘要: The present invention pertains to an apparatus and process for storing information object collections in a database. Examples of such object collections are nested tables and variable length arrays. In an embodiment, the invention provides mechanisms and methods for storing nested tables in either a base table of a database, or an index-organized table. In one embodiment, mechanisms and methods are provided for storing variable length arrays into a table column, as a large object ("LOB"), or as an index-organized table. The invention also provides methods and mechanisms for accessing data from these storage mediums.

    摘要: Disclosed is a method, system, and program product for providing an efficient mechanism to provide updateable relational views over XML. This will allow application developers to write both queries and updates using a relational (SQL) syntax, even though the underlying data is stored as XML. According to some approaches, this is accomplished by implementing a reverse mapping from the data within the views to the node addresses of the corresponding data in the underlying XML document.

    摘要: A method, computing device, and a non-transitory computer-readable medium is provided for facilitating a context-aware search on documents stored in an unstructured database column. The database server determines whether a document stored in an unstructured database object is marked up according to a recognized markup language. Documents that conform to the markup language are indexed with value-to-node mappings and node-to-physical-location mappings to provide a context-aware search of marked up nodes within the documents. Documents that do not conform to the markup language are indexed with value-to-document mappings to provide a full-text search of the documents. The database server evaluates a context-aware search against documents that conform to the markup language within the unstructured column without requiring the user identify the documents as XML documents and store the documents in an XMLType structured column.
