甲骨文 - 错误的交换磁盘分区列表 - 范围分区

Question

我想在下面的例子架构使用Exchange PARTITION：

CREATE TABLE TEMP_TABLE_00(
    CONTACT_ID NUMBER, 
    SECONDARY_CONTACT_FLAG NUMBER, 
    SOURCE_SYSTEM VARCHAR2(10 CHAR), 
    START_DATE DATE, 
    ACTIVE NUMBER, 
    SECONDARY_CONTACT_FLAGS NUMBER GENERATED ALWAYS AS (ACTIVE || SECONDARY_CONTACT_FLAG) VIRTUAL, 
    CONSTRAINT pk_temp_table_00 PRIMARY KEY (CONTACT_ID)) 

PARTITION BY LIST (SECONDARY_CONTACT_FLAGS) 
SUBPARTITION BY RANGE (START_DATE) 
(PARTITION p_ac_00 VALUES ('00') 
    (SUBPARTITION sp_ac_00_before_2014 VALUES LESS THAN (TO_DATE ('01.01.2014', 'DD.MM.YYYY')), 
    SUBPARTITION sp_ac_00_201401  VALUES LESS THAN (TO_DATE ('01.02.2014', 'DD.MM.YYYY')) 
)  
) 
ENABLE ROW MOVEMENT; 

create table TARGET_TABLE(
    CONTACT_ID NUMBER, 
    SECONDARY_CONTACT_FLAG NUMBER, 
    SOURCE_SYSTEM VARCHAR2(10 CHAR), 
    START_DATE DATE, 
    ACTIVE NUMBER, 
    SECONDARY_CONTACT_FLAGS NUMBER GENERATED ALWAYS AS (ACTIVE || SECONDARY_CONTACT_FLAG) VIRTUAL, 
    CONSTRAINT pk_target_table PRIMARY KEY (CONTACT_ID)) 
PARTITION BY LIST (secondary_contact_flags) 
SUBPARTITION BY RANGE (START_DATE) 
(PARTITION p_ac_00 VALUES ('00') 
    (SUBPARTITION sp_ac_00_before_2014 VALUES LESS THAN (TO_DATE ('01.01.2014', 'DD.MM.YYYY')), 
    SUBPARTITION sp_ac_00_201401  VALUES LESS THAN (TO_DATE ('01.02.2014', 'DD.MM.YYYY')) 
    ), 
    PARTITION p_ac_10 VALUES ('10') 
    (SUBPARTITION sp_ac_10_before_2014 VALUES LESS THAN (TO_DATE ('01.01.2014', 'DD.MM.YYYY')), 
    SUBPARTITION sp_ac_10_201401  VALUES LESS THAN (TO_DATE ('01.02.2014', 'DD.MM.YYYY')) 

), 
    PARTITION p_ac_01 VALUES ('01') 
    (SUBPARTITION sp_ac_01_before_2014 VALUES LESS THAN (TO_DATE ('01.01.2014', 'DD.MM.YYYY')), 
    SUBPARTITION sp_ac_01_201401  VALUES LESS THAN (TO_DATE ('01.02.2014', 'DD.MM.YYYY')) 

), 
    PARTITION p_ac_11 VALUES ('11') 
    (SUBPARTITION sp_ac_11_before_2014 VALUES LESS THAN (TO_DATE ('01.01.2014', 'DD.MM.YYYY')), 
    SUBPARTITION sp_ac_11_201401  VALUES LESS THAN (TO_DATE ('01.02.2014', 'DD.MM.YYYY')) 

) 
) 
ENABLE ROW MOVEMENT; 

INSERT INTO DM_KSCTSC.TEMP_TABLE_00 (CONTACT_ID, SECONDARY_CONTACT_FLAG, SOURCE_SYSTEM, START_DATE, ACTIVE) VALUES (1, 0, 'ABC', TO_DATE('20140101', 'YYYYMMDD'), 0); 
commit; 

当试图交换分区：

alter table target_table exchange partition p_ac_00 with table TEMP_TABLE_00 without validation; 

即使分区的结构是相同的，Oracle返回一个

ORA-14292：分区类型的表必须匹配子分区离子型 复合分区

是否有另一种解决方案，而不是单独交换每个子分区？

Answer 1

为了能够在分区表（PT）和非分区表（TMP）之间交换分区，TMP表必须具有与PT的分区相同的结构。

I.e.如果PT被分区，则TMP是非分区的。

如果对PT进行组合划分，则TMP按照与PT的子划分相同的方式划分。

在你的情况是在TMP表（TEMP_TABLE_00），它必须是由RANGE（同TARGET_TABLE的子分区）划分问题

CREATE TABLE TEMP_TABLE_00(
    CONTACT_ID NUMBER, 
    SECONDARY_CONTACT_FLAG NUMBER, 
    SOURCE_SYSTEM VARCHAR2(10 CHAR), 
    START_DATE DATE, 
    ACTIVE NUMBER, 
    SECONDARY_CONTACT_FLAGS NUMBER GENERATED ALWAYS AS (ACTIVE || SECONDARY_CONTACT_FLAG) VIRTUAL, 
    CONSTRAINT pk_temp_table_00 PRIMARY KEY (CONTACT_ID)) 

PARTITION BY RANGE (START_DATE) 

    ( PARTITION sp_ac_00_before_2014 VALUES LESS THAN (TO_DATE ('01.01.2014', 'DD.MM.YYYY')), 
    PARTITION sp_ac_00_201401  VALUES LESS THAN (TO_DATE ('01.02.2014', 'DD.MM.YYYY')) 
)  

ENABLE ROW MOVEMENT; 

在此设置的交换分区的作品。
