    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;
    create index idx_local_book2 on book1 (val) global
                                         *
    An error occurred on line 1. :
    ORA - 01408: column list is already indexed
