摘要: Dynamic return type generation in a database system. A request is received to execute a first function. A second function is executed if the first function is defined to return data in a first type of data structure. When executed, the second function returns formatting information that indicates an arrangement of fields of data within the first type of data structure. The first function is executed to obtain a collection of data formatted according to the first type of data structure, and the collection of data is organized according to the formatting information returned by the second function.

摘要: A request to execute a query is received in a database system. In response, the database system determines that a collection of data elements to be returned by the query corresponds to a first data structure not defined within a type dictionary of the database system. The database system obtains attribute values that describe respective data fields within the first data structure, and records, within the type dictionary, a first data type definition that specifies the data fields described by the attribute values.

摘要: Techniques for partitioning nested tables are provided. A parent table includes a column for collection items. A nested table is created for storing items that belong to the collection items. The nested table is partitioned to create a plurality of nested table partitions. Each nested table partition is a distinct, separately stored structure within a database. How the nested table is partitioned may, or may not, be based on how the parent table is partitioned. For example, a nested table may be partitioned based on the same criteria in which the parent table is partitioned. As another example, a nested table may be partitioned, whereas the parent table is not partitioned.

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: Methods and apparatus for enabling a plurality of table columns arranged to be associated with large objects (LOBs) to share a single LOB data segment within a database are disclosed. According to one aspect of the present invention, a method for allocating space associated with at least a first column arranged to accommodate LOB data and a second column arranged to accommodate LOB data includes allocating a first LOB data segment. The method also includes associating both the first column and the second column with the first LOB data segment.
