尝试创建索引时出现错误：

ORA-14188：子分区列必须形成唯一索引的键列的子集

我应该如何更改我的创建索引 SQL 语句来解决这个问题？

【问题讨论】：

  • 最好发布您在创建表和索引时使用的实际 SQL，而不是来自 dbms_metadata 的 500 行转储以及与问题无关的存储设置。

标签： sql oracle indexing


【解决方案1】：

分区的限制是，您希望以与其表相同的方式分区的任何唯一索引/约束必须共享相同的分区键。该表由 PARTITION_TIME 和 SESSION_ID 分区，因此唯一索引也需要包含这些列。

create table ratedevent 
( created_time     number
, session_id       varchar2(4000)
, schema_id        number(*,0)
, rated_event      blob
, partition_time   number )
lob (rated_event) store as basicfile
partition by list (partition_time) automatic 
subpartition by hash (session_id) 
subpartitions 32
( partition old_time  values (-1) );

create unique index ib_ratedevent on ratedevent 
(partition_time, session_id, created_time)
local;

如果它不是唯一的，则不需要：

create index ib_ratedevent2 on ratedevent (created_time) local;
