  • Patent number: 11775517
    Abstract: Query content-based data generation includes obtaining a query having an outer query and one or more subqueries, converting predicates of a subquery to be predicates of the outer query, and thereby obtain a transformed query, generate from the transformed query a query block having a list of predicate(s) selected from the transformed query, obtaining column information based on the list of predicate(s) and using the column information to select data for a dataset such that data records from the dataset are produced as results to executing the obtained query against the dataset.

  • Publication number: 20230306012
    Abstract: Disclosed are techniques for relational database locks based on columns. Database transactions may be targeted to specific columns of one or more records, instead of the entire row for those records, using primary keys. Column locks on specific keys are stored separately than column locks on ranges of keys, which are both checked when requesting a new column lock for either a single key or a range of keys. When a threshold number of columns for a given record, or range of records/keys, have been locked, the column locks for that record, or range of records, can be combined into a single row level lock to reduce resource costs for maintaining multiple concurrent locks.

  • Publication number: 20230297596
    Abstract: Performing a mutual exclusion data class analysis is provided. A data class group of a plurality of data class groups that a matching data class is a member of is identified. The matching data class matches data in a plurality of rows of a column in a data asset. Data classes included in the data class group that the matching data class is a member of are identified. A mutual exclusion data class is filtered from the data class group to form a filtered data class group for the column. The filtered data class group is run against the column of the data asset decreasing processing time and resource utilization of a computer.

  • Patent number: 11762859
    Abstract: Embodiments of the present disclosure relate to an approach for database query. According to the approach, a query for a group of data records is received. At least one index is created on at least one field of the data records and comprises index entries for storing and sorting respective values of the at least one field of the data records. It is determined if the query satisfies a predetermined condition. In response to the query satisfying the predetermined condition, a result of the query is determined by skipping at least a part of operations required by the query based on the at least one index.

  • Patent number: 11734277
    Abstract: An approach is provided for optimizing a database buffer pool. Based on statistics about read and write operations in a range of pages, the range of pages is determined to be a candidate for a hot read range for which locks and latches are avoided in processing operations in the hot read range. Using an on-time trigger or pre-trigger process, the hot read range is created from the range of pages by marking start and end points in the range of pages. Write operation(s) are determined to be included in the hot read range by marking an object control block. The write operation(s) are added to a write pending list. The read operations in the hot read range are performed without a latch or lock. The write operation(s) are merged from the write pending list to the range of pages and the write operation(s) are performed.

  • Publication number: 20230240213
    Abstract: The disclosure relates to the technical field of soybean breeding, in particular to a method for improving soybean hybrid yield. In the method, fertile soybean is taken as a male parent, and pollen from the male parent is prepared into a pollen compound solution, which is carried with a spraying device to be directionally spayed to a female parent for hybridization, where the female parent is a genic male sterile soybean plant. By preparation of an appropriate proportion of pollen compound solution and pollination assisted by artificial spraying, the disclosure may not only enhance the pollen activity, but also improve the pollen utilization rate and greatly improve the efficiency of soybean hybrid production, thereby improving the soybean yield. It effectively saves human resources, improves the efficiency of soybean hybrid production, and meets the needs of soybean industry development.
