oracle表分区

1.Range(范围)分区

创建分区表

CREATE TABLE TABLE_PARTITION(
COL1   NUMBER,
COL2   VARCHAR2(100)
)
partition by range(COL1)(
partition TAB_PARTOTION_01 values less than (450000),
partition TAB_PARTOTION_02 values less than (900000),
partition TAB_PARTOTION_03 values less than (1350000),
partition TAB_PARTOTION_04 values less than (1800000),
partition TAB_PARTOTION_OTHER values less THAN (MAXVALUE)
);

插入测试数据

INSERT INTO TABLE_PARTITION(COL1,COL2)
VALUES(1,'数据测试');
INSERT INTO TABLE_PARTITION(COL1,COL2)
VALUES(23,'数据测试');
INSERT INTO TABLE_PARTITION(COL1,COL2)
VALUES(449000,'数据测试');

INSERT INTO TABLE_PARTITION(COL1,COL2)
VALUES(450000,'数据测试');

INSERT INTO TABLE_PARTITION(COL1,COL2)
VALUES(1350000,'数据测试');

INSERT INTO TABLE_PARTITION(COL1,COL2)
VALUES(900000,'数据测试');

INSERT INTO TABLE_PARTITION(COL1,COL2)
VALUES(1800000-1,'数据测试');
COMMIT;

查看分区里的数据

SELECT * FROM TABLE_PARTITION partition(TAB_PARTOTION_02);
