在 Oracle PL/SQL 中使用 ONLINE 将非分区表转换为分区表 [英] Convert Non-partition table to partitioned table using ONLINE in Oracle PL/SQL

问题描述

我知道我们无法将现有的非分区表转换为分区表，但来自 Oracle 的以下链接建议在ONLINE"关键字的帮助下我们可以做到.

I got to know as we cannot convert existing non-partitioned table to partitioned table but the below link from the Oracle suggest that with the help of "ONLINE" keyword we can do it.

https://docs.oracle.com/en/database/oracle/oracle-database/12.2/vldbg/evolve-nopartition-table.html#GUID-5FDB7D59-DD05-40E4-8AB4-AF82EA0D0FE5

CREATE TABLE my_tab ( a NUMBER(38,0), b NUMBER(38,0)); 

ALTER TABLE MY_TAB MODIFY PARTITION BY RANGE (a) INTERVAL (1000) (   
    PARTITION p1 VALUES LESS THAN (1000)) ONLINE;

但它对我不起作用，抛出错误为无效的分区名称".

But it's not working for me, throwing error as "Invalid Partition Name".

我不想使用dbms_redefinition.

推荐答案

如果您使用的是 Oracle 12c Release 2，您可以使用单个 ALTER 来转换非分区表分区一:

If you are using Oracle 12c Release 2 you could use single ALTER to convert non-partitioned table to partitioned one :

CREATE TABLE my_tab ( a NUMBER(38,0), b NUMBER(38,0)); 

ALTER TABLE MY_TAB MODIFY PARTITION BY RANGE (a) INTERVAL (1000) (   
    PARTITION p1 VALUES LESS THAN (1000)) ONLINE;
