摘要： A suggested query execution plan is used as a constraint on a guided optimization process such that all execution plans that do not conform to the suggested execution plan are eliminated as possible alternatives. If the guided optimization process successfully generates a resulting execution plan, then the result will conform to the suggested execution plan. If the guided optimization process fails to generate a resulting execution plan, then it may be determined that the suggested execution plan is invalid.

摘要： Indexed views or materialized views are used as a secondary index on a base table with multi-valued attributes. This provides for using the index to search in the nested data. Moreover, indexing is provided on the result of an unnest operation. Indexing a view on the result of an unnesting operation provides the ability to index the contents of a nested collection. One such unnesting operation is “cross apply unnest”. This provides additional options for a query execution plan, leading to a more optimized query. A back-join is provided from the indexed view to the base table to allow fields from the base table that are not present in the indexed view to be included in a result of a query on the table which is processed using the indexed view as an access path. This provides a means of including columns in the query result that are not in the indexed view but are in the base table. The back-join is supported from a single-table indexed view to the base table via a unique clustering key which acts as a logical row locator. Thus, the system can back-join to the base table from an indexed view via the unique clustering key. These features allow the use of indexed views to index a table on the contents of multi-set or multi-valued attributes.

摘要： A query optimizer produces a preferred execution plan by utilizing statistics on views. These provide the optimizer with statistical information beyond that available on tables, for example, with information on the result of scalar or relational expressions. Pre-derived accurate statistics are thus available which are used to improve the accuracy of estimation and thus increase the quality and reliability of the query processor. Transformations of expressions and sub-expressions of candidate plans produce equivalent sub-expressions. Where those sub-expressions include references to views, an estimation of the cardinality and other execution statistics for the sub-expression can be made using the view statistics. This can be used to estimate the cardinality for all equivalent sub-expressions, leading to higher accuracy for the estimate.
摘要翻译： 查询优化器通过利用视图统计信息生成首选执行计划。 这些为优化器提供超出表上可用的统计信息，例如，具有关于标量或关系表达式的结果的信息。 因此，可以使用预先导出的精确统计量来提高估计的准确性，从而提高查询处理器的质量和可靠性。 候选计划的表达式和子表达式的转换产生等效的子表达式。 在这些子表达式包括对视图的引用的情况下，可以使用视图统计信息来估计子表达式的基数和其他执行统计信息。 这可以用于估计所有等效子表达式的基数，导致估计的更高的准确性。

摘要： A method of satsfying a database query includes evaluating certain joins on a per-segment basis. An expression tree is produced for the query, and the expression tree is evaluated to identify joins whose operands are two instances of the same relation and whose join predicate conjunctively includes an equality comparison between two instances of the same column. When such a join is identified, it may be evaluated by segmenting the operand relation according to the columns that are compared for equality in the predicate. The join is then evaluated by performing the join operation separately on each segment. Segments may be spooled separately, thereby exploiting the efficiencies obtained by spooling even where the entire relation is too large to fit in the spool. Execution iterators are provided for spooling successive segments and for applying the join to the spooled segment.
