Oracle数据库创建只读用户

创建一个只读用户user2,只能查询管理员用户user1下的表,不能增删改。

操作环境:PL/SQL Developer

1、用管理员用户user1登录,创建用户user2、并授权

--创建用户user1,密码123456
create user user2 identified by 123456;
--授权
grant connect to user2;
grant create synonym to user2;
grant create session to user2;

2、授予user2的查询表权限:复制下面的查询结果,执行

select 'grant select on '||owner||'.'||object_name||' to user2;'
 from dba_objects
 where owner in ('USER1')
 and object_type in ('VIEW','PROCEDURE','TABLE','FUNCTION');

3、为user2创建同义词:复制下面的查询结果,执行

select 'create or replace SYNONYM user2.' || object_name|| ' FOR ' || owner || '.' || object_name|| ';' 
from dba_objects
where owner in ('USER1')
and object_type in ('VIEW','PROCEDURE','TABLE','FUNCTION');

测试:
用user2登录数据库,查询正常,增删改提示没有权限。
