A warehouse fact table in your Oracle 12c Database is range-partitioned by month and accessed frequently with queries that span multiple partitions The table has a local prefixed, range partitioned index. Some of these queries access very few rows in some partitions and all the rows in other partitions, but these queries still perform a full scan for all accessed partitions. This commonly occurs when the range of dates begins at the end of a month or ends close to the start of a month. You want an execution plan to be generated that uses indexed access when only a few rows are accessed from a segment, while still allowing full scans for segments where many rows are returned. Which three methods could transparently help to achieve this result?() [" Using a partial local Index on the warehouse fact table month column with indexing disabled to the table partitions that return most of their rows to the queries."," Using a partial local Index on the warehouse fact table month column with indexing disabled for the table partitions that return a few rows to the queries."," Using a partitioned view that does a UNION ALL query on the partitions of the warehouse fact table, which retains the existing local partitioned column."," Converting the partitioned table to a partitioned view that does a UNION ALL query on the monthly tables, which retains the existing local partitioned column"," Using a partial global index on the warehouse fact table month column with indexing disabling for the table partitions that return most of their rows to the queries."," Using a partial global index on the warehouse fact table month column with indexing disabled for the table partitions that return a few rows to the queries."] 国家多渠道筹集社会保险资金。县级以上人民政府对社会保险事业给予必要的经费支持。 施工组织总设计的主要内容包括()。 ["建设项目的工程概况","施工方案的选择","各项资源需求量计划","施工总进度计划"] 系统在运行中受到大干拢,同步发电机能否维持稳定运行称为()。 ["动态稳定","静态稳定","系统抗干扰能力"] Click the Exhibit button.
