- The current materialized views selection approaches are static, which greatly disobey dynamic nature of OLAP and DSS. 然而现有支持物化视图自动选择的方法是静态的,它违背了联机分析处理(OLAP)和决策支持系统(DSS)的动态本质。
- Views selection - choose a pre-defined named view of your data which would filter, sort, and reorder the fields based on the criteria defined in the view. 视图选择-选择一个预先定义的命名查看您的资料,这些资料将过滤,排序,并重新安排各个领域的基础上,标准界定的看法。
- Views selection - choose a pre-defined named view of your data which would filter,sort, and reorder the fields based on the criteria defined in the view. 视图选择 -选择一个预先定义的命名查看您的资料,这些资料将过滤,排序,并重新安排各个领域的基础上,标准界定的看法。
- This paper gives an cost model of materialized view.Materialized view selection algorithm and strategy using genetic rules are presented. 论文给出实视图代价估算模型,利用遗传规则,提出实视图选取的方法和策略。
- The expression defining the computed column can have the same form as a more complex expression in the view select list. 定义计算列的表达式可与视图选择列表中的较复杂表达式具有相同的形式。
- For views that have INSTEAD OF triggers, the view select list must contain enough information to build values for all nonnull columns in the base tables modified by the trigger. 对于具有INSTEAD OF触发器的视图,视图选择列表必须包含足够的信息,以为由触发器修改的基表中所有非空列生成值。
- In this paper, we use directed-acyclic graph (DAG) to represent a query processing, then define a cost model and a query efficiency model, and finally put forward an algorithm for materialized views selection. 在考虑空间约束的基础上,提出一种物化视图选择方法,并给出了切实可行的算法步骤。
- Select the View Selected Addresses link to view a list of the addresses you have marked for deletion. 选取检视选择的地址连结以查看您标明要删除的地址列表。
- If AVG(expression) is specified in queries referencing the indexed view, the optimizer can frequently calculate the needed result if the view select list contains SUM(expression) and COUNT_BIG(expression). 如果在引用索引视图的查询中指定了AVG(expression),则当视图SELECT列表中包含SUM(expression)和COUNT_BIG(expression)时,优化器可经常计算所需结果。
- In turn, each view selects into its display context as a foreground or background palette, depending on whether the view is the active one or not. 然后,每个视图在其显示上下文中选择作为前景或背景调色板,具体取决于该视图是否活动。
- Each view selects its palette into the display context as a background palette, however, yielding the foreground palette to the other application. 但是,每个视图在显示上下文中选择其调色板作为背景调色板,并为其他应用程序产生前景调色板。
