RESOURCE                       CREATE TYPE

RESOURCE                       CREATE TABLE

RESOURCE                       CREATE CLUSTER

RESOURCE                       CREATE TRIGGER

RESOURCE                       CREATE OPERATOR

RESOURCE                       CREATE SEQUENCE

RESOURCE                       CREATE INDEXTYPE

RESOURCE                       CREATE PROCEDURE

已选择16行。

10.查看oracle的版本,其实查看oracle的版本还有许多其他方法,不过我认为下面这个方法
比较好记。
SQL> select version from v$instance;

10.1.0.2.0
注意:
我做该实验的oracle版本是10.1.0.2.0。

CONNECT角色在10g以后就只有create session的权限了,以前其他版本的权限都被取消了。

当RESOURCE角色被授予一个用户后,该用户自动拥有了unlimited tablespace的系统权限。
