For example , you can query tables in other databases 例如,您可以查詢其他數(shù)據(jù)庫中的表。
Materialized query table - 物化查詢表
The database user should only be allowed to query tables and views that contain input data 應該只允許數(shù)據(jù)庫用戶查詢包含輸入數(shù)據(jù)的表和視圖。
Not supported are range clustered tables , materialized query tables , and typed tables 不支持范圍簇表( rct ) 、物化查詢表( mqt )和有類型的表。
Sql server mobile also includes sql server mobile query analyzer , a tool you can use to query tables in a database Sql server mobile還包含sql server mobile查詢分析器,這是一種可以用來查詢數(shù)據(jù)庫表的工具。
Materialized query tables that can be defined over queries referencing both relational and nonrelational nicknames to locally cache the query results 物化查詢表,可以在引用關系和非關系昵稱的查詢上定義物化查詢表,以便本地緩存查詢結(jié)果。
Using the olap metadata , cube views optimization advisor can now analyze underlying dimensional data and create the most efficient set of materialized query tables mqts for your olap applications 使用olap元數(shù)據(jù), cube views optimization advisor現(xiàn)在可以分析基本的維度數(shù)據(jù)以及為olap應用程序創(chuàng)建一組最有效的實例化的查詢表( mqt ) 。
An introduction of design method of fuzzy controller is given . the method of the combination of the genetic algorithms and fuzzy control is studied . the method of optimizing the fuzzy control query table by using the genetic algorithms is discussed 介紹了模糊控制器的設計方法,并研究了遺傳算法與模糊控制的融合方式,探討了用遺傳算法直接優(yōu)化模糊控制決策表。
Then a kind of fuzzy - smith control strategies for a large dead - time system is studied and improved . the simulation results show that the fuzzy - smith control method has some excellent performances , which is suitable for systems with deadtime - varying parameters . considering that the conventional fuzzy has a shortcoming of invariable fuzzy rules , an algorithm of adjustable fuzzy rules based on a single neural cell is proposed in this paper , which is used for modifying the fuzzy control query table on - line 本文分析了模糊控制、神經(jīng)網(wǎng)絡和常規(guī)控制算法存在的不足,研究了如何將各算法的優(yōu)勢互補,相互融合,形成復合的自適應智能控制算法;針對大時滯系統(tǒng)的特點研究了fuzzy - smith控制算法,并在前人基礎上做出了一定的改進研究,進一步提高了fuzzy - smith控制算法的性能;又將常規(guī)pid與神經(jīng)網(wǎng)絡有機結(jié)合,研究了單神經(jīng)元pid控制算法:針對常規(guī)模糊控制不可調(diào)整模糊控制規(guī)則的局限,本文利用單神經(jīng)元的自適應、自學習能力對模糊規(guī)則庫進行了間接在線自調(diào)整。
