oracle数据表创建分区

场景: 遇到1亿数据量的数据需要根据用户名做些数据统计分析,想直接做些聚合计算基本没可能,于是打算先根据日期按照年月创建分区,然后对各个分区分别进行统计,最后汇总结果。

操作方式,新建分区表,然后用ETL工具抽取源并写入新表。

create table TEMP_TEST (  log_id              NUMBER(20),  user_id             NUMBER(20),  user_name           NVARCHAR2(200),  money               NUMBER(30,8),  history_total       NUMBER(30,8),  order_id            NVARCHAR2(100),  money_type_id       NUMBER(20),  reason_id           NUMBER(20),  operation_user_name NVARCHAR2(200),  operation_user_ip   NVARCHAR2(100),  remark              NVARCHAR2(200),  osn                 NVARCHAR2(100),  isn                 NVARCHAR2(100),  return_sn           NVARCHAR2(100),  repeate_flag        NUMBER(3),  create_date         DATE,  modify_date         DATE,  status              NUMBER(20),  batch_id            NUMBER(38)) nologgingpartition  by range (create_date) (   partition  create_date1500 values less than (TO_DATE(2015-01-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1501 values less than (TO_DATE(2015-02-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1502 values less than (TO_DATE(2015-03-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1503 values less than (TO_DATE(2015-04-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1504 values less than (TO_DATE(2015-05-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1505 values less than (TO_DATE(2015-06-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1506 values less than (TO_DATE(2015-07-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1507 values less than (TO_DATE(2015-08-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1508 values less than (TO_DATE(2015-09-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1509 values less than (TO_DATE(2015-10-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1510 values less than (TO_DATE(2015-11-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1511 values less than (TO_DATE(2015-12-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1512 values less than (TO_DATE(2016-01-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1601 values less than (TO_DATE(2016-02-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1602 values less than (TO_DATE(2016-03-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1603 values less than (TO_DATE(2016-04-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1604 values less than (TO_DATE(2016-05-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1605 values less than (TO_DATE(2016-06-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1606 values less than (TO_DATE(2016-07-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1607 values less than (TO_DATE(2016-08-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1608 values less than (TO_DATE(2016-09-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1609 values less than (TO_DATE(2016-10-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1610 values less than (TO_DATE(2016-11-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1611 values less than (TO_DATE(2016-12-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS,  partition  create_date1612 values less than (TO_DATE(2017-01-01 00:00:00,yyyy-mm-dd hh24:mi:ss)) tablespace DW_STG_TBS)
