文档解释

ORA-14639: SUBPARTITIONS clause can be specfied only for Hash, Composite Range Hash table/partition

Cause: Attempted to specify SUBPARTITIONS clause on table that is not partitioned by the Composite Range-Hash method

Action: Reissue the command after ensuring that the SUBPARTITIONS clause is not specified, to specify a template for a Composite Range List object use the SUBPARTITION TEMPLATE clause

官方解释

常见案例

当在建立哈希、综合型范围型和哈希分区表时，使用SUBPARTITIONS字句就可能出现ORA-14639错误。例如：

创建表：

CREATE TABLE orders

(order_id NUMBER(20),

order_date DATE,

SUBPARTITIONS 4

)

PARTITION BY RANGE (order_date)

(PARTITION p1 VALUES LESS THAN (’01-JAN-2018′));

当执行上述语句时，就会报 ORA-14639错误。

正常处理方法及步骤

1. 若要将表分区化，就不能使用SUBPARTITIONS字句，而要使用SUBPARTITION字句去创建有多种子分区的分区表。

2. 创建子分区的语句：

SUBPARTITION BY HASH (order_id)

SUBPARTITIONS 4

例如：

CREATE TABLE orders

(order_id NUMBER(20),

order_date DATE

)

PARTITION BY RANGE (order_date)

(PARTITION p1 VALUES LESS THAN (’01-JAN-2018′)

SUBPARTITION BY HASH (order_id)

SUBPARTITIONS 4

);
