摘要
A system, method, and computer program product for processing XML queries over relational data and meta-data using a relational database system. The invention runs a query to generate a view definition, so a regular query processor can handle queries on a mix of data and meta-data. Names of desired tables are data-dependent, so the invention represents a default XML view as an XML query over the relational tables, gets the table names and table data by recursively invoking the query processor (first by querying the catalog table, and then querying base data according to a new construct). The invention thus processes queries over table names in addition to table values.
