Abstract: Techniques are provided for gathering statistics in a database system. The techniques involve gathering some statistics using an “on-the-fly” technique, some statistics through a “high-frequency” technique, and yet other statistics using a “prediction” technique. The technique used to gather each statistic is based, at least in part, on the overhead required to gather the statistic. For example, low-overhead statistics may be gathered “on-the-fly” using the same process that is performing the operation that affects the statistic, while statistics whose gathering incurs greater overhead may be gathered in the background, while the database is live, using the high-frequency technique. The prediction technique may be used for relatively-high overhead statistics that can be predicted based on historical data and the current value of predictor statistics.

Abstract: Embodiments of the present disclosure disclose a terminal holder and a far-field voice interaction system. A specific implementation of the terminal holder includes: a far-field voice pickup device and a voice analysis device. The far-field voice pickup device receives voice sent by a user, and sends the voice to the voice analysis device. The voice analysis device analyzes the voice, determines whether the voice contains a preset wake-up word, and sends the voice to a terminal in communication connection with the terminal holder when the preset wake-up word is contained. This embodiment receives voice sent by a user through the terminal holder supporting a far-field voice pickup function, thereby facilitating the far-field voice control over the terminal.

Abstract: Techniques are described for responding to aggregate queries using optimizer statistics already available in the data dictionary of the database in which the database object targeting by the aggregate query resides, without the user creating any additional objects (e.g. materialized views) and without requiring the objects to be loaded into volatile memory in a columnar fashion. The user query is rewritten to produce a transformed query that targets the dictionary tables to form the aggregate result without scanning the user tables. “Accuracy indicators” may be maintained to indicate whether those statistics are accurate. Only accurate statistics are used to answer queries that require accurate answers. The accuracy check can be made during runtime, allowing the query plan of the transformed query to be used regardless of the accuracy of the statistics. For queries that request approximations, inaccurate statistics may be used so long as the statistics are “accurate enough”.

Abstract: Techniques are provided for merging (a) statistics associated with data added to a table in a bulk load operation with (b) statistics associated with data that existed in the table before the bulk load operation. The statistics associated with the bulk load data are generated on-the-fly during the bulk load, and are merged with the pre-existing statistics as part of the same transaction that is used to perform the bulk load operation. Consequently, execution plans for queries that are assigned snapshot times after the commit time of the bulk load transaction will be selected based on the new statistics, while execution plans for queries that are assigned snapshot times before the commit time of the bulk load transaction will be selected based on the pre-existing statistics.

Abstract: A structure of an aquarium heater with off-water overheat protection, wherein a control box with a control circuit is set inside.

Abstract: A table is processed to determine an approximate NDV for a plurality of groups. For each row, a group based is identified based on one or more group-by columns. A hashed valued is generated by applying a uniform hash function to a value in an NDV column. The hashed value is assigned to a particular bucket based on the values at a first set of bit positions in a binary representation of the hashed value. A bit position value is determined based on for a remaining portion of the binary representation of the hashed value. The bit position value is based on a number of ordered bits in the hashed value that match a particular bit pattern. For each group identified, a maximum bit position (MBP) table is generated. The MBP table stores, for one or more buckets, the maximum bit position value determined for hashed values assigned to a particular bucket.

Abstract: Techniques for processing queries are provided. In one approach, an execution plan for a query includes multiple sub-plans, one or more of which are selected at runtime while one or more other sub-plans are not executed during execution of the execution plan. In another approach, data about misestimate is generated and stored persistently for subsequent queries. In another approach, statistics for a database object are generated automatically and efficiently while the database object is created or data items are added thereto. In another approach, a hybrid histogram is created that includes a feature of frequency histograms and a feature of height-balanced histograms. In another approach, computer jobs are executed in such a way to avoid deadlock. In another approach, changes to a database object trigger a hard parse of a query even though an execution plan already exists for the query.
