ALTER TABLE SALES MERGE PARTITIONS P1,P2 INTO PARTITION P2; 五、拆分分区 拆分分区将一个分区拆分两个新分区,拆分后原来分区不再存在。注意不能对HASH类型的分区进行拆分。 ALTER TABLE SALES SBLIT PARTITION P2 AT(TO_DATE('2003-02-01','YYYY-MM-DD')) INTO (PARTITION P21,PARTITION P22); 六、接合...

PARTITION partition2015 VALUES LESS THAN(to_date('2016-01-01:00:00:00','yyyy-mm-dd hh24:mi:ss')) ); (3.2)按”月“自动创建分区(关键字:NUMTOYMINTERVAL) 例子:创建按月自动分区表,按照员工生日(birthday字段),每月一个分区。 CREATE TABLE interval_month_table01 ...
Interval Partition也可以创建复合分区: 1. Interval-range2. Interval-hash3. Interval-list 以下是创建Interval分区表示例: sys@ORCL> CREATE TABLE interval_sales( prod_id NUMBER(6), cust_id NUMBER, time_id DATE, channel_id CHAR (1), promo_id NUMBER(6), quantity_sold NUMBER(3), amount_sold ...
PARTITION p3 VALUES LESS THAN (MAXVALUE)); create table t1 (id1 number,id2 number) partition by range (id1) subpartition by list (id2) (partition p11 values less than (11) (subpartition subp1 values (1)) ); 索引分区: CREATE INDEX month_ix ON sales(sales_month) ...
