INTERVAL分区是Oracle11g新增的特性,它是针对Range类型分区的一种功能拓展。对连续数据类型的Range分区,如果插入的新数据值与当前分区均不匹配,Interval-Partition特性可以实现自动的分区创建。 示例: createtable TMP_LXQ_1 ( proposalnovarchar2(22), startdatedate ) partitionby range(STARTDATE) interval(numtoymin...
二、interval分区和range分区的转换 ALTERTABLE TMP_LXQ_1 SET INTERVAL (numtoyminterval(1,'year')); 对于INTERVAL分区表,新增的超过分区上限的数据会自动导致对应的INTERVAL分区被建立。 同样INTERVAL分区表可以方便的转化为RANGE分区表,只需要不输入INTERVAL的值即可: ALTER TABLETMP_LXQ_1SET INTERVAL (); 三、...

■ A MAXVALUE literal can be defined for the highest partition. MAXVALUE represents a virtual infinite value that sorts higher than any other possible value for the partition key, including the null value. 由此可知,range分区是应用最广的分区方式,它是以列的值的范围来做为分区的划分条件,将记录存...
The ALTER TABLE syntax allows you to transform existing range partitioned table to the interval partition as: ALTERTABLEtable_nameSETINTERVAL( … ); For additional information about the ALTER TABLE interval partitioning syntax, seeDatabase Compatibility for Oracle® Developer’s Guide...
OraclePartitionByRange语法是一种将表数据分成多个分区的方法。该方法基于表的某个列,将数据分成多个分区,每个分区包含按范围划分的特定行数。以下是Oracle Partition By Range语法的详细说明: 1.创建分区表 CREATE TABLE table_name ( column1 datatype [ NULL | NOT NULL ], column2 datatype [ NULL | NOT ...
