[Partition][Index]对于Partition表而言，是否Global Index 和 Local Index 可以针对同一个字段建立？

对于Partition表而言，是否Global Index 和 Local Index 可以针对同一个字段建立？

实验证明，对单独的列而言，要么建立 Global Index, 要么建立 Local Index。不能既建立 Global Index, 又建立 Local Index

=== Test Case ===
#### Testcase - 0809 - 1

It is not possible to create both Global Index and Local Index for the same single column.

CREATE TABLE book 1 (id NUMBER, val integer)
PARTITION BY RANGE (val)
(PARTITION book 1 p 1 VALUES LESS THAN (100),
 PARTITION book 1 p 2 VALUES LESS THAN (200),
 PARTITION book 1 p 3 VALUES LESS THAN (MAXVALUE));


insert into book1 values ​​(1,90);
insert into book1 values ​​(2, 95);

insert into book 1 values ​​(3, 110);
insert into book 1 values ​​(4, 120);

insert into book 1 values ​​(5, 130);
insert into book 1 values ​​(6, 140);

commit;

create index idx_local_book 1 on book 1 (val) local;

SQL> create index idx_local_book 2 on book 1 (val) global;
