1.3. 創建其他類型分區表

1.3.1. 用多列分區鍵創建范圍分區表

SQL> create table aning_mutilcol_range

2 (aning_id number,

3 aning_name varchar2(100),

4 aning_year number,

5 aning_month number,

6 aning_day number,

7 aning_amount number

8 )

9 partition by range (aning_year,aning_month)

10 (partition mutil_range2011 values less than (2012,1),

11 partition mutil_range_1203 values less than (2012,4),

12 partition mutil_range_1205 values less than (2012,6),

13 partition mutil_range_1302 values less than (2013,3),

14 partition mutil_range_max values less than (maxvalue,0)

15 );

Table created.

1.3.2. 基于虛擬列創建分區表

使用虛擬列做為子分區鍵值

SQL> create table aning_virtual_col

2 (aning_id number,

3 aning_name varchar2(100),

4 aning_date date,

5 aning_quantity number,

6 aning_amount number,

7 aning_total as (aning_quantity * aning_amount)

8 )

9 partition by range(aning_date) interval (numtoyminterval(1,'month'))

10 subpartition by range (aning_total)

11 subpartition template

12 (subpartition vircol_small values less than (1000),

13 subpartition vircol_medium values less than (5000),

14 subpartition vircol_large values less than (10000),

15 subpartition vircol_max values less than (maxvalue)

16 )

17 (partition vircol2010 values less than (to_date('2011-01-01','yyyy-mm-dd'))
