范围分区表是通过 create table 语句的 partition by range 子句来创建的,分区的范围通过 values less than 子句指定,其指定的是分区的上限(不包含),所有大于等于指定值的数据被分配至下一个分区,除了第一个分区,每个分区的下限即前一个分区的上限: create table members ( ...
create tabletable_name(...)partition byhash(column_name)(partition p1,partition p2,partition p3,...); List分区 List分区与range分区和hash分区都有类似之处,该分区与range分区相似的是也需要你指定列的值,但你必须明确指定值,并不能指定范围。与hash分区不同之处在于你能控制记录存储在哪个分区。但它的分...
组合分区呢在10g中有两种:range-hash,range-list。注意顺序,根分区只能是range分区,子分区可以是hash分区或list分区。 如: createtabletest ( transaction_id numberprimarykey, transaction_datedate)partitionbyrange(transaction_date) subpartitionbyhash(transaction_id) ...
Note: you cannot create global indexes for hash partitions or sub partitions The partitioning function of Oracle is powerful. But using it, finding two is not convenient: The first is the existing table, and there is no method that can be directly converted into partition tables. However, Orac...
