day13_普通表转换成分区表——具体实现

CREATE TABLE lipengfei ( ID VARCHAR2(32) unique, PLATFORM_ID VARCHAR2(32), AC_ID VARCHAR2(32), TYPE_ID VARCHAR2(32), USER_ID VARCHAR2(32), PRIZE_ID VARCHAR2(32), PRIZE_LEVEL VARCHAR2(3), WIN_DATE DATE, IS_WIN VARCHAR2(3), IS_GET VARCHAR2(3), GET_TIME DATE, RAND_CODE VARCHAR2(32), PRIZE_ONLY VARCHAR2(40), PUB_DATE DATE, USER_MAIL_ID VARCHAR2(32), PRO_CODE VARCHAR2(20), OPP_ID VARCHAR2(32), TARGET_USER VARCHAR2(50)) PARTITION BY LIST (PRO_CODE) ( PARTITION P_098 VALUES ('098'), PARTITION P_011 VALUES ('098_011'), PARTITION P_013 VALUES ('098_013'), PARTITION P_018 VALUES ('098_018'), PARTITION P_019 VALUES ('098_019'), PARTITION P_010 VALUES ('098_010'), PARTITION P_091 VALUES ('098_091'), PARTITION P_090 VALUES ('098_090'), PARTITION P_097 VALUES ('098_097'), PARTITION P_031 VALUES ('098_031'), PARTITION P_034 VALUES ('098_034'), PARTITION P_036 VALUES ('098_036'), PARTITION P_030 VALUES ('098_030'), PARTITION P_038 VALUES ('098_038'), PARTITION P_075 VALUES ('098_075'), PARTITION P_017 VALUES ('098_017'), PARTITION P_076 VALUES ('098_076'), PARTITION P_071 VALUES ('098_071'), PARTITION P_074 VALUES ('098_074'), PARTITION P_051 VALUES ('098_051'), PARTITION P_059 VALUES ('098_059'), PARTITION P_050 VALUES ('098_050'), PARTITION P_083 VALUES ('098_083'), PARTITION P_081 VALUES ('098_081'), PARTITION P_085 VALUES ('098_085'), PARTITION P_086 VALUES ('098_086'), PARTITION P_079 VALUES ('098_079'), PARTITION P_084 VALUES ('098_084'), PARTITION P_087 VALUES ('098_087'), PARTITION P_070 VALUES ('098_070'), PARTITION P_088 VALUES ('098_088'), PARTITION P_089 VALUES ('098_089'), PARTITION P_NULL VALUES (default) );
2、创建一个新表lipengfei，与YX_PRIZE_RECORD表结构一模一样,lipengfei是分区表，但是没有数据！ Alter table lipengfei NOLOGGING; 操作lipengfei表不记录日志，加快操作速度！
3、编写存储过程，从YX_PRIZE_RECORD_HISTORY查询数据insert到lipengfei表，批量提交！
4、alter table YX_PRIZE_RECORD_HISTORY rename to YX_PRIZE_RECORD_HISTORY_BAK;(原历史表保留，等改造成功后，再删除！)
5、alter table lipengfei rename to YX_PRIZE_RECORD_HISTORY;
6、create index I_AC_ID_IS_GET_PRO_CODE on YX_PRIZE_RECORD_HISTORY(ac_id,is_get,pro_code) local;
7、 Alter table YX_PRIZE_RECORD_HISTORY LOGGING; 操作A表记录日志！
