Oracle追加分区过程

项目中预留几年的分区已经用完了，继续添加新建分区，步骤如下：

1）如果已经创建最大分区，应该先进行删除最大分区，脚本如下：

// 删除最大分区max 
alter table t_tfm_link_dir_day_flow drop partition LD1DPMAX;

2）继续添加新分区，脚本如下，

ALTER TABLE t_tfm_link_dir_day_flow ADD   
 partition LD1DP202101 values less than (TO_DATE(' 2021-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    tablespace TFM_TB1;

3）再次添加最大分区，脚本如下，

ALTER TABLE t_tfm_link_dir_day_flow ADD   
 partition LD1DPMAX values less than (MAXVALUE)
    tablespace TFM_TB1;

现场的实际更新脚本如下：

--删除最大分区max    注意 t_tfm_link_dir_day_flow是表名，tb1是表空间名称，后面时间
alter table t_tfm_link_dir_day_flow drop partition LD1DPMAX;
