试验步骤如下：
1.创建个分区表
SQL> create table p_range_test 2 (id number,name varchar2(100)) 3 partition by range(id)( 4 partition t_p1 values less than (10), 5 partition t_p2 values less than (20), 6 partition t_p3 values less than (30) 7 ); Table created. 2.查第一步创建好分区表的信息 SQL> col TABLE_NAME for a20 SQL> col partition_name for a20 SQL> col HIGH_VALUE for a10 SQL> col TABLESPACE_NAME for a15 SQL> select table_name,partition_name,high_value,tablespace_name from user_tab_partitions where table_name='P_RANGE_TEST' order by partition_position; TABLE_NAME PARTITION_NAME HIGH_VALUE TABLESPACE_NAME -------------------- -------------------- ---------- --------------- P_RANGE_TEST T_P1 10 TP1 P_RANGE_TEST T_P2 20 TP1 P_RANGE_TEST T_P3 30 TP1 从上面看出已有3个分区 3.添加一个分区t_p4 SQL> alter table p_range_test add partition t_p4 values less than(40); Table altered. 顺序添加完成，当然这个不是LZ想要的吧？ 4.再第三步添加好分区的信息 SQL> select table_name,partition_name,high_value,tablespace_name from user_tab_partitions where table_name='P_RANGE_TEST' order by partition_position; TABLE_NAME PARTITION_NAME HIGH_VALUE TABLESPACE_NAME -------------------- -------------------- ---------- --------------- P_RANGE_TEST T_P1 10 TP1 P_RANGE_TEST T_P2 20 TP1 P_RANGE_TEST T_P3 30 TP1 P_RANGE_TEST T_P4 40 TP1 从这个实验结果可以看到t_p4分区已经创建成功 5.对于LZ的问题：如果在创建RANGE分区表的时候指定了maxvalue，不可以添加分区（需要使用split方法来处理） 继续实验来验证是否可行 ！！！ 6.创建带有maxvalue的分区表 SQL> drop table p_range_test purge; create table p_range_test (id number,name varchar2(100)) partition by range(id)( partition t_p1 values less than (10), partition t_p2 values less than (20), partition t_p3 values less than (30), partition t_pmax values less than (maxvalue)); Table dropped. SQL> 2 3 4 5 6 Table created. 7.此时添加分区时会报如下的错误 SQL> alter table p_range_test add partition t_p4 values less than(40); alter table p_range_test add partition t_p4 values less than(40) * ERROR at line 1: ORA-14074: partition bound must collate higher than that of the last partition 添加分区失败？那有没有办法搞定呢，对于牛B的oracle来说肯定有办法了，处理方法就是使用split来搞！ 8.再查一下当前的分表的信息 SQL> select table_name,partition_name,high_value,tablespace_name from user_tab_partitions where table_name='P_RANGE_TEST' order by partition_position; TABLE_NAME PARTITION_NAME HIGH_VALUE TABLESPACE_NAME -------------------- -------------------- ---------- --------------- P_RANGE_TEST T_P1 10 TP1 P_RANGE_TEST T_P2 20 TP1 P_RANGE_TEST T_P3 30 TP1 P_RANGE_TEST T_PMAX MAXVALUE TP1 9.注意，这步就是关键的一步！！！！！使用split完成上面没有完成的分区任务 SQL> alter table p_range_test split partition t_pmax at (40) into (partition, partition t_pmax); Table altered. 10.再查一下当前的分表的信息 SQL> select table_name,partition_name,high_value,tablespace_name from user_tab_partitions where table_name='P_RANGE_TEST' order by partition_position; TABLE_NAME PARTITION_NAME HIGH_VALUE TABLESPACE_NAME -------------------- -------------------- ---------- --------------- P_RANGE_TEST T_P1 10 TP1 P_RANGE_TEST T_P2 20 TP1 P_RANGE_TEST T_P3 30 TP1 P_RANGE_TEST SYS_P41 40 TP1 P_RANGE_TEST T_PMAX MAXVALUE TP1
