    摘要： An improved method and system for processing a structured document stored in a database is disclosed. The method includes identifying strings that are processed by the database, assigning an identifier to each of the strings, storing each of the strings and the assigned identifier in a table in the database, where the table is a global database table, and utilizing the table to replace the strings with their assigned identifiers throughout the database, where the identifiers are used during document processing.

    摘要： An improved method and system for performing path-level access control evaluation for a structured document in a collection, where the structured document includes a plurality of nodes and each of the nodes is described by a path, is disclosed. The method comprises providing a cache for temporarily storing a cache entry for a path associated with a node of the plurality of nodes, receiving a query that includes a request to access the node, checking the cache entry for the path associated with the node, and determining whether to grant access to the node based on the cache entry.

    摘要： The SQL compiler and SQL executor in a database management system are extended to process queries requiring streaming mode processing of data stored in a table. A scan operator performs table access functions during execution of the streaming mode query. The scan operator first performs an initial scan to access rows in a specified database table, and then performs a delta scan to access new rows added to the table, as well as rows modified by other queries. The scan operator continues to process new data added to the table until the initiating user or application closes the associated cursor. A set of data structures are provided to keep track of active scan operators, including a session control block that includes fields for keeping track of whether the scan operator is performing an initial scan or a delta scan. The session control block also includes, for streaming mode scan operators, a delta scan list of new and modified rows to be processed in the delta scan. When a transaction terminates, any streaming mode scan operators whose operation was suspended because of rows locked by the transaction are automatically rescheduled for execution.

    摘要： A method and system for querying a structured document stored in its native format in a database, where the structured document includes a plurality of nodes that form a hierarchical node tree, is disclosed. The method includes providing at least one child pointer in each of the plurality of nodes, where the at least one child pointer points to a corresponding child node of the plurality of nodes, and storing a hint in each of the at least one child pointers. The hint is then utilized to navigate the hierarchical node tree during query evaluation.

    摘要： The SQL compiler and SQL executor in a database management system are extended to execute statements for dequeuing rows from a database table and statements that both updating tuples and return those tuples to a calling application. During execution of a select statement that includes an embedded update or delete operation, a table access operator accesses a defined range of rows in a database table. The table access operator receives from a calling application a request for rows dequeued from the database table. The table access operator responds to the requests for rows by returning to the calling application qualifying rows, if any, from the database table and also by performing the embedded delete or update operation. The SQL executor returns control to the calling application only after all rows deleted or updated by the table access operator have been sent to the calling application.
