oracle将普通表变分区表
数据是否同步仍未考证，但方法比较简单，可以用于参考：
思路：
1、创建中间表
CREATE TABLE A_T_NEW ("ID" VARCHAR2(32 BYTE) NOT NULL ENABLE,
"DRIVERCODE" VARCHAR2(64 BYTE),
"DRIVERTIME" TIMESTAMP (6),
"LNG" VARCHAR2(32 BYTE),
"LAT" VARCHAR2(32 BYTE),
"IS_DELETED" VARCHAR2(20 BYTE) DEFAULT '0')
PARTITION BY RANGE (DRIVERTIME)(
PARTITION P1 VALUES LESS THAN (TO_TIMESTAMP('2016-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P2 VALUES LESS THAN (TO_TIMESTAMP('2016-04-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P3 VALUES LESS THAN (TO_TIMESTAMP('2016-07-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P4 VALUES LESS THAN (TO_TIMESTAMP('2016-10-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P5 VALUES LESS THAN (TO_TIMESTAMP('2017-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P6 VALUES LESS THAN (TO_TIMESTAMP('2017-04-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P7 VALUES LESS THAN (TO_TIMESTAMP('2017-07-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P8 VALUES LESS THAN (TO_TIMESTAMP('2017-10-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P9 VALUES LESS THAN (TO_TIMESTAMP('2018-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P10 VALUES LESS THAN (TO_TIMESTAMP('2018-04-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P11 VALUES LESS THAN (TO_TIMESTAMP('2018-07-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P12 VALUES LESS THAN (TO_TIMESTAMP('2018-10-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')),
PARTITION P13 VALUES LESS THAN (MAXVALUE));
commit;
2、验证原表是否可以在线迁移
--验证原表是否可以在线迁移
exec dbms_redefinition.can_redef_table('tms','T_TMS_VEHICLE_DRIVER_REC');
3、在新开会话进行迁移，这里我没有新开会话，而是直接进行了迁移。
exec dbms_redefinition.start_redef_table('tms','T_TMS_VEHICLE_DRIVER_REC','A_T_NEW');
exec dbms_redefinition.sync_interim_table('tms','T_TMS_VEHICLE_DRIVER_REC','A_T_NEW');
exec dbms_redefinition.finish_redef_table('tms','T_TMS_VEHICLE_DRIVER_REC','A_T_NEW');
提交，会发现原有的表'T_TMS_VEHICLE_DRIVER_REC' 已添加分区完毕。但这时，原有PK，注释等并没有加入到新表。
4、更改主键（删除表，删除原有pk，如果不用同名约束，可以直接alter table）
drop table A_T_NEW purge ; alter table T_TMS_VEHICLE_DRIVER_REC add constraint T_TMS_VEHICLE_DRIVER_REC_PK primary key (id);
5、加注释（请预先保留SQL）
COMMENT ON COLUMN "TMS"."T_TMS_BILL"."ID" IS 'ID'; COMMENT ON COLUMN "TMS"."T_TMS_BILL"."BILL_CODE" IS '运单号'; .....
