ORA-14006 When Using For Clause In Partition Maintenance Command

刘泽宇

现象：
ORA-14006 when partition operation is used with FOR clause for partitioned index or for partitioned index organized table (IOT).

ALTER TABLE <IOT> MODIFY PARTITION FOR(10) ....
ALTER INDEX <partitioned index> MODIFY PARTITION FOR(10) ....

e.g.
alter index idx2 modify partition for(10) nocompress
                                  *
ERROR at line 1:
ORA-14006: invalid partition name

alter table iot1 modify partition for(10) coalesce
*
ERROR at line 1:
ORA-25189: illegal ALTER TABLE option for an index-organized table
ORA-14006: invalid partition name

This occurs for other partition maintenance operations (e.g. split, drop, rebuild)  for partitioned index and for IOT.

原因：
Unpublished minor bug, that is with development at the time of writing this article.

处理方法：
1./ Determine the corresponding partition/subpartition by looking up the PARTITION_NAME
SUBPARTITION_NAME, HIGH_VALUE columns of the corresponding dictionary view:
user|dba|all_tab_partitions
user|dba|all_tab_subpartitions
user|dba|all_ind_partitions
user|dba|all_ind_subpartitions

2./ Use the partition name instead of the FOR clause.

e.g.
alter index idx2 modify partition pi1 nocompress;
alter table iot1 modify partition p2 coalesce;
