Oracle之 赋予resource角色自动赋予UNLIMITED TABLESPACE权限，回收同理。

创建一个角色

create role role_test1;
grant create session to role_test1;

创建一个用户

create user user_test1 identified by test1;

赋予resource角色和role_test1角色

grant resource to user_test1;
grant role_test1 to user_test1;

此时user_test1拥有权限：

select * from dba_role_privs where grantee = 'USER_TEST1';
select * from dba_sys_privs where grantee = 'USER_TEST1';

得到

角色：resource和role_test1

权限：UNLIMITED TABLESPACE

得知赋予resource角色会自动给用户（而不是角色）赋予UNLIMITED TABLESPACE权限。

回收resource角色之后，也会自动回收UNLIMITED TABLESPACE权限

revoke resource from user_test1;

select * from dba_role_privs where grantee = 'USER_TEST1';
select * from dba_sys_privs where grantee = 'USER_TEST1';
