全局分区索引和本地索引示例

--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‘)
