ORA-14175: a subpartition maintenance operation may not be combined with other operations ORACLE 报错 故障修复 远程处理

文档解释

ORA-14175: a subpartition maintenance operation may not be combined with other operations

Cause: ALTER TABLE or ALTER INDEX statement attempted to combine a subpartition maintenance operation (e.g. MOVE SUBPARTITION) with some other operation (e.g. MODIFY PARTITION ADD SUBPARTITION or PCTFREE) which is illegal

Action: Ensure that a subpartition maintenance operation is the sole operation specified in ALTER TABLE or ALTER INDEX statement; operations other than those dealing with subpartitions, default attributes of partitioned tables/indices or specifying that a table be renamed (ALTER TABLE RENAME) may be combined at will

ORA-14175表明子分区维护操作不可与其他操作混合。

官方解释

ORA-14175的原因是子分区的维护操作不可与其他操作混合。对表进行子分区维护操作时,如果有其他操作(例如表定义更改,ADD/MOD add_extend_clause,添加/删除子分区等),则会导致此错误。

常见案例

比如,你想改变表的定义,例如添加列,并且想对表的子分区进行维护:

ALTER TABLE my_table

ADD my_col NUMBER

ALTER SUBPARTITION my_subpart MAINTAIN_PART_INDEXES;

执行此操作时,会出现ORA-14175错误,因为子分区维护操作不能与其他操作混合,就像上面的例子,改变表定义和子分区维护操作不能同时进行。

正常处理方法及步骤

1. 先执行子分区维护操作:

ALTER SUBPARTITION my_subpart MAINTAIN_PART_INDEXES;

2. 然后再对表做其他操作:

ALTER TABLE my_table

ADD my_col NUMBER;
