- A materialized view can be partitioned. You can define a materialized view on a partitioned table and one or more indexes on the materialized view. 一个物化视图可以被分割。你能定义一个物化视图在一个分割表,也能定义在物化视图的一个或多个索引上。
- RESERVATIONS.HOTEL_ID GROUP BY ARUP.RESERVATIONS.CUST_NAME, ARUP.RESERVATIONS.RESV_ID, ARUP.HOTELS.CITY UNDO DROP MATERIALIZED VIEW ARUP. 相反,需要对每一个物化视图的结构进行目视检查,这是非常不实际的。
- "RESERVATIONS" WITHROWID, SEQUENCE ("RESV_ID","HOTEL_ID","CUST_NAME")INCLUDING NEW VALUESIMPLEMENTATION ALTER MATERIALIZED VIEW LOG FORCE ON "ARUP". 相反,需要对每一个物化视图的结构进行目视检查,这是非常不实际的。

- The radical database will update when the information source change and can incite the materialized view to update and maintain . 当信息源发生变化时,基库随着更新,同时触发多实化视图的更新与维护。
- SQL> CREATE MATERIALIZED VIEW mv_ emp_ pk REFRESH FAST START WITH SYSDATE NEXT SYSDATE+2 WITH PRIMARY KEY AS SELECT* FROM emp@ remote_ db; Materialized view created. 在上面的例子中,物化视图数据的第一个副本在创建时生成,以后每两天刷新一次.
- The latter is one way to maintain the materialized view at the DW without access to the base relations by replicating all or parts of the base data at the DW. 视图自维护方法通过在数据仓库中复制所有或部分源关系的数据,从而使维护数据仓库实化视图时不需要访问数据源。
- Implement of materialized view is a key technology and efficient solution of advancing system response time.But the maintenance problem of materialized view is involved. 摘要实现实体化视图是提高系统响应时间的一个关键技术和有效的解决方案,在具体的实现过程中面临着实体化视图的维护问题。
- The format of the inserted and deleted tables passed to an INSTEAD OF trigger defined on a view matches the select list of the SELECT statement defined for the view. 传递给为视图定义的INSTEAD OF触发器的插入的和删除的表的格式与为该视图定义的SELECT语句的选择列表的格式一致。
- I have already spoken about the dialectical materialist view of motive and effect. 关于动机和效果的辩证唯物主义观点,我在前面已经讲过了。
- Queries are then directed to the materialized view and not to the underlying detail tables or views. 于是,查询直接作用与物化视图,而不是其潜在的详细表和视图。
- In data warehouses, materialized views are used to compute and store aggregated data such as sums and averages. 在数据仓库中,物化视图被用来计算和存储总计性的数据,比如求和和平均数。
- 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。
- Unlike indexes, materialized views can be accessed directly using a SELECT statement. 不同于索引,物化视图可以使用SELECT语句直接访问。
