ORA-14270: table is not partitioned by Range, System, Hash or List method ORACLE 报错 故障修复 远程处理
文档解释
ORA-14270: table is not partitioned by Range, System, Hash or List method
Cause: The table in ALTER TABLE MODIFY PARTITION { UNUSABLE LOCAL INDEXES | REBUILD UNUSABLE LOCAL INDEXES } statement is not partitioned by Range,List,System, or Hash method which is illegal.
Action: Ensure that the table is partitioned by Range,List,System, or Hash method
ORA-14270 错误指示表没有按照Range(范围),System(系统),Hash(散列)或List(列表)方法进行分区。
官方解释
ORA-14270 表没有按照有效的分区方法进行分区。在Oracle中,只能使用以下分区策略:Range(范围),System(系统),Hash(散列)或List(列表)。
常见案例
某个表没有按照Range, System, Hash or List分区策略进行分区,则会导致上述ORA-14270错误;
正常处理方法及步骤
(1)检查表是否已分区:select * from user_tab_partitions;
(2)查看表是否按照符合的分区策略:select * from user_part_tables;
(3)如果表没有分区,可以使用ALTER TABLE语句按Range(范围),System(系统),Hash(散列)或List(列表)方法进行分区。
(1)建立分区函数:
CREATE FUNCTION partition_range_func (PN VARCHAR2)
RETURN NUMBER
PARALLEL_ENABLE AGGREGATE USING
case
when PN=’VIP’ THEN 1
when PN=’Normal’ THEN 2
else 3
end;
(2)建立分区表:
CREATE TABLE Pay_table (Pay_ID number,Pay_Name,Varchar2(20))
PARTITION BY RANGE (partition_range_func(Pay_Name))
(PARTITION p1_VIP VALUES LESS THAN (1),
PARTITION p2_normal VALUES LESS THAN (2),
PARTITION p3_other VALUES LESS THAN (MAXVALUE));
