摘要： A set of algebraic rules applicable to a query are identified, wherein each of the algebraic rules represents a relationship between two columns in a relational database table. A source column is identified by searching the query for a source predicate, wherein the source predicate is a range predicate. One or more candidate target columns are identified by searching the set of algebraic rules, wherein each of the candidate target columns occurs on one side of a binding expression and the source column occurs on the other side of the binding expression. For each of the one or more candidate target columns, a bounds subquery that provides a lower bound and an upper bound for a new range predicate is derived and he new range predicate is introduced into the query, wherein the query is executed to retrieve data from one or more data stores.

摘要： A system and method are provided for updating database statistics for use in generating query execution plans. A first query for a database is received, for example by a compiler, and the compiler accesses statistics associated with the first query for optimizing a query execution plan for the first query. The statistics may be accessed from a first cache. If the statistics retrieved from the first cache are determined to be stale, the system obtains updated statistics and may store them in a temporary cache. The stale statistics in the first cache are marked as invalid. Existing queries using the first cache may continue to use the first cache, while new queries may be provided with updated statistics.

摘要： A system and method transform queries with subqueries, using window aggregation. An optimizer in a relational database management system transforms queries to optimize their efficiency and speed. The method transforms queries that have a subquery, replacing the subquery with a window aggregation function. In the case of a correlated subquery, the window aggregation function is partitioned by a correlated column of a correlated table. All data in the main select clause, or outer block, of the query that was obtained through references to the correlated table is instead obtained through the new window aggregation subquery. By using window aggregation, the aggregation is performed at the same time as the selection of relevant data from the correlated table, thereby compiling all needed data in a single pass through the table or view. Reducing the number of times that tables or views are accessed reduces the computational demands of a query.
摘要翻译：系统和方法使用子查询转换查询，使用窗口聚合。关系数据库管理系统中的优化器可以转换查询以优化其效率和速度。该方法转换具有子查询的查询，使用窗口聚合函数替换子查询。在相关子查询的情况下，窗口聚合函数由相关表的相关列划分。通过引用相关表获得的查询的main select子句或外部块中的所有数据都是通过新的窗口聚合子查询得到的。通过使用窗口聚合，在从相关表中选择相关数据的同时进行聚合，从而在通过表或视图的单次传递中编译所有需要的数据。降低访问表或视图的次数减少了查询的计算需求。
