oracle分区使用详解

create table fq_test (
id number,
name varchar2(32),
create_time date)
partition by range (create_time) interval (numtoyMinterval (1,'MONTH'))
(
partition p_2024_07_12 values less than (to_date('2024-07-12', 'yyyy-mm-dd'))
);

create table fq_test (
id number,
name varchar2(32),
create_time date)
partition by range (create_time) interval (NUMTODSINTERVAL  (1,'day'))
(
partition p_2024_07_12 values less than (to_date('2024-07-12', 'yyyy-mm-dd'))
);

PARTITION BY RANGE (created)
INTERVAL (NUMTOYMINTERVAL(1, 'YEAR'))  -- 自动按年扩展分区
(PARTITION p_start VALUES LESS THAN (DATE '2026-01-01'));--起始时间是20260101
