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： 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： 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.

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 efficiently storing data in a variable array (VARRAY) of a database system are disclosed. A method for storing data in a VARRAY having an associated large object segment in a system having a memory and a kernel includes determining a size of data to be inserted into the VARRAY. The method also includes determining when the size of the data is less than a threshold value, and storing the data as inline raw data in a column of the VARRAY that is present in the memory when the size of the data is less than the threshold value. When the size of the data is not less than the threshold value, the data is stored in a large object that is associated with the VARRAY. Further, when a VARRAY type is evolved to have a larger maximum size, existing data is not migrated or transformed.
摘要翻译： 公开了将数据有效地存储在数据库系统的可变数组（VARRAY）中的方法和装置。 在具有存储器和内核的系统中具有相关联的大对象段的VARRAY中存储数据的方法包括确定要插入到VARRAY中的数据的大小。 该方法还包括当数据的大小小于阈值时确定数据的大小是否小于阈值，并且当数据的大小小于阈值时，将数据作为内联原始数据存储在存在于存储器中的VARRAY的列中 。 当数据的大小不小于阈值时，数据存储在与VARRAY相关联的大对象中。 此外，当VARRAY类型演变为具有较大的最大大小时，现有数据不会迁移或转换。

摘要： The present invention provides a light string with reinforced wires. The light string includes a plurality of reinforced wires and a plurality of lamps electrically connected in series via the plurality of reinforced wires. Each reinforced wire includes a plurality of conducting wires, an outer insulating sheath covering the plurality of conducting wires and one or more reinforcing strands configured between an inner side surface and an outer side surface of the outer insulating sheath and extending along a direction parallel to a central longitudinal axis of the reinforced wire. The bending resistant performance of the electric wire between each two adjacent lamps is improved greatly, the fatigue strength of the electric wire is much better than that of an ordinary electric wire, and the tensile strength of the electric wire is improved.
