    摘要: Optimization is provided for database statements involving XML data, e.g., XPath and XQuery, which operate over views that use aggregate set operators, e.g., UNION ALL. As part of a “view merge” stage of query transformation, the query that operates over the view is merged with a query that defines the view. One or more expressions (e.g., operators, predicates, virtual table constructs) from the query that operates over the view are then “pushed down” to operate on the individual underlying XML data constructs. “Branch elimination” is performed based on the structure of the view and the query acting over the view, based on which it is possible to determine whether any of the sub-queries, if executed, would result in the return of zero rows. If so, then such branches are eliminated from the transformed query, leaving a reduced set of data containers on which to execute the query.

    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: The invention relates to a method for determining the amount of oat flour addition in compound flours and noodles, and it belongs to the field of food detection technology. Based on the similarity of the fatty acid composition between oat and wheat, the quantitative analysis index used for measuring the oat flour addition was determined. Based on the differences of fatty acid contents in oat and wheat, the relationship between the changing trend of fatty acid composition and oat flour content in compound powders or noodles is employed to quantitatively determine the amount of oat added to these compound flours or noodles. The invention provides a highly sensitive and feasible method for safety monitoring and quality control of oat flours and oat noodles.
