    摘要: A query access plan for executing a database query is dynamically selected from among multiple alternative query access plans based on the availability of computer resources allocated for running the query. Preferably, a first query access plan is generated based on resources then available, and if it is possible to provide additional resources, one or more alternative plans are generated based on the additional resources. If an alternative plan is significantly better than the original plan based on a comparison of query related parameters, the alternative is chosen for executing the query. Additional resources for running the query may be provided from logically partitioned and/or grid environments.

    摘要: A method, apparatus, system, and signal-bearing medium that in an embodiment replace an element in a query with a backup if the element is not available, but the backup is available. An element may also be removed from the query if the element is not required. In various embodiments, the element may be a table or a user-defined function. In this way, the query may still execute even if the element is not available.

    摘要: A system, method and article of manufacture for presentation of data on a display device and, more particularly, for managing presentation of data in a tabular form on a display device. One embodiment provides a method of managing display of requested data on a display device. The method comprises, in response to a request for data, receiving the requested data in a tabular form having a plurality of columns and rows ordered according to an initial order; re-ordering at least one of the columns and rows, wherein the re-ordering is done on the basis of rules configured to intelligently arrange presentation of the requested data to a user; and outputting the re-ordered requested data for display on the display device.

    摘要: A method, apparatus, system, and signal-bearing medium that in an embodiment track a history of statements that query data from a database. When a new statement is received, the history is searched for a correlation between the new statement and previous statements. The correlation is based on host variables in the history and the new statement. When a correlation is found, a prediction is made for the next statement to be received based on the previous statement in the history for which the correlation was found. The prediction is then used to retrieve pages from the database into a cache, which may be used by a subsequent statement.
