範圍 - 區間複合分區 - Oracle 11g R2

Question

我想要做的是創建一個表，複合範圍分區 - 分區按月和按分區劃分在同一個分區鍵上。

我已經嘗試使用maxvalue或天間隔的子分區，但它仍然無法正常工作，我出於主意。分區範圍是2年，所以代碼很長。我有一個分區範圍的片段。

PARTITION BY RANGE (SCL_DATE) INTERVAL (NUMTOYMINTERVAL(1, 'MONTH')) 
    SUBPARTITION BY RANGE(SCL_DATE) 
    (
     PARTITION JAN14 VALUES LESS THAN (TO_DATE('01/02/2014', 'DD/MM/YYYY')) 
     (
     SUBPARTITION JAN14_1 VALUES LESS THAN(TO_DATE('01/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_2 VALUES LESS THAN(TO_DATE('02/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_3 VALUES LESS THAN(TO_DATE('03/01/2014', 'DD/MM/YYYY')), 
     PARTITION JAN14_4 VALUES LESS THAN(TO_DATE('04/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_5 VALUES LESS THAN(TO_DATE('05/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_6 VALUES LESS THAN(TO_DATE('06/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_7 VALUES LESS THAN(TO_DATE('07/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_8 VALUES LESS THAN(TO_DATE('08/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_9 VALUES LESS THAN(TO_DATE('09/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_10 VALUES LESS THAN(TO_DATE('10/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_11 VALUES LESS THAN(TO_DATE('11/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_12 VALUES LESS THAN(TO_DATE('12/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_13 VALUES LESS THAN(TO_DATE('13/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_14 VALUES LESS THAN(TO_DATE('14/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_15 VALUES LESS THAN(TO_DATE('15/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_16 VALUES LESS THAN(TO_DATE('16/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_17 VALUES LESS THAN(TO_DATE('17/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_18 VALUES LESS THAN(TO_DATE('18/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_19 VALUES LESS THAN(TO_DATE('19/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_20 VALUES LESS THAN(TO_DATE('20/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_21 VALUES LESS THAN(TO_DATE('21/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_22 VALUES LESS THAN(TO_DATE('22/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_23 VALUES LESS THAN(TO_DATE('23/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_24 VALUES LESS THAN(TO_DATE('24/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_25 VALUES LESS THAN(TO_DATE('25/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_26 VALUES LESS THAN(TO_DATE('26/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_27 VALUES LESS THAN(TO_DATE('27/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_28 VALUES LESS THAN(TO_DATE('28/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_29 VALUES LESS THAN(TO_DATE('29/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_30 VALUES LESS THAN(TO_DATE('30/01/2014', 'DD/MM/YYYY')), 
     SUBPARTITION JAN14_31 VALUES LESS THAN(TO_DATE('31/01/2014', 'DD/MM/YYYY')) 
), 

Answer 1

我認爲按月份和按子日期劃分分區是沒有用的。只需按月份（或按日期，取決於您的需要）進行分區。

無論如何，這應該SQL工作：

CREATE TABLE THE_TABLE 
(
    SCL_DATE TIMESTAMP(0), 
    SCL_DAY NUMBER GENERATED ALWAYS AS (EXTRACT(DAY FROM SCL_DATE)) VIRTUAL, 
    ... more COLUMNS 
) 
PARTITION BY RANGE (SCL_DATE) INTERVAL (INTERVAL '1' MONTH) 
    SUBPARTITION BY LIST (SCL_DAY) 
    SUBPARTITION TEMPLATE 
    (SUBPARTITION P01 VALUES (1), 
     SUBPARTITION P02 VALUES (2), 
     SUBPARTITION P03 VALUES (3), 
     ... 
     SUBPARTITION P30 VALUES (30) 
     SUBPARTITION P31 VALUES (31) 
    ) 
( 
    PARTITION P_201401 VALUES LESS THAN (TIMESTAMP '2014-01-01 00:00:00') 
);
