全局分区索引和本地索引示例，全局索引示例

--建表
create table lm_t1(id number,name varchar2(10),sex varchar2(10))
partition by range(id)
(
partition p1 values less than(10),
partition p2 values less than(20),
partition pm values less than(maxvalue)
);

--全局分区索引(只支持hash和range)
create index g_ind_lm_t1 on lm_t1(id)
global partition by range(id)
(
partition p1 values less than(10),
partition p2 values less than(20),
partition pm values less than(maxvalue)
);

create index gh_ind_lm_t1 on lm_t1(name)
global partition by hash(name)
partitions 3;
--本地分区索引
create index l_ind_lm_t1 on lm_t1(sex)
local(partition p1,partition p2,partition p3);

--查看信息
select * from user_indexes d where d.table_name=upper('lm_t1');
select * from user_part_indexes  d where d.table_name = upper('lm_t1');
select * from user_ind_partitions d where d.index_name in ('G_IND_LM_T1','L_IND_LM_T1','GH_IND_LM_T1')
