Interval partitioning is an extension of the familiar range partitioning scheme. Range partitioning is ideal for partitioning historical data. You use range partitioning to organize data by time intervals on a column of type DATE. The boundaries you set for the range partitions determine how the dat...

(4)间隔分区(interval partitioning); (5)引用分区(reference partitioning); (6)组合分区(composite partitioning)。 二、分区表的实现方式 1、范围分区(range partition table) Range分区是应用范围比较广的表分区方式,它是以列的值的范围来做为分区的划分条件,将记录存放到列值所在的range分区中。如果插入的数据无...

1. Tables greater than 2GB should always be considered for partitioning.(表数据量大于2GB时应该考虑使用分区) 2. Tables containing historical data, in which new data is added into the newest partition. A typical example is a historical table where only the current month's data is updatable and...

As of Oracle9i Release 2, Oracle also supports two INTERVAL datatypes, INTERVAL YEAR TO MONTH and INTERVAL DAY TO SECOND, which are used for storing a specific amount of time. This data can be used for date arithmetic. Temporal validity Oracle Database 12c introduced a new concept related to...
