答案是D

对应的SQL:

CREATE TABLE tb1 (id INT, name VARCHAR(30), age INT, phone VARCHAR(20), addr VARCHAR(100), PRIMARY KEY(id)) PARTITION BY HASH(id) PARTITIONS 16; 
CREATE INDEX i1 ON tb1 (name); 
CREATE index i2 ON tb1 (phone) GLOBAL; 
CREATE INDEX i3 ON tb1 (age) GLOBAL PARTITION BY RANGE(age) (PARTITION p0 VALUES LESS THAN(18), PARTITION p1 VALUES LESS THAN(30), PARTITION p2 VALUES LESS THAN(60), PARTITION p3 VALUES LESS THAN(MAXVALUE));

这是实测的

[zmix]

不是说了oracle模式，你这里mysql模式吧

[Coca-cola]

oracle默认global

[try_again]

oboracle创建索引默认全局索引。
当前使用的是obmysql模式，且社区版不支持oboracle模式

那应该怎么选
