Oracle创建只读账号的详细步骤_Oracle

需求说明

现有数据库账号：hepsusr：具有完整权限，增删改查。

需要创建一个数据库账号：htreader，对hepsusr账号下所有的表具有只读权限。

第一步：创建只读账号

				?

									--创建只读账号 第一步

									create user htreader identified by 123456;

第二步：赋予账号连接数据库等基本权限

				?

									--赋予htreader连接等常规权限

									grant connect to htreader;

									grant create view to htreader;

									grant create session to htreader;

									grant create synonym to htreader;

第三步：获取原账号的查询权限

				?

									获取原账号hepsusr用户的所有查询表权限

									select 'grant select on '||owner||'.'||object_name||' to htreader;'

									from dba_objects

									where owner in ('hepsusr')

									and object_type='table';

									--查询结果为新账号的赋值语句，如下图

第四步：将原账号权限赋值为新账号

				?

									在原账号hepsusr下执行，将原账号的查询权限 赋值给新账号

									-------

									grant select on hepsusr.entry_cert to htreader;

									grant select on hepsusr.sub_message_info to htreader;

									grant select on hepsusr.entry_cert_relation to htreader;

									grant select on hepsusr.entry_cert_relation to htreader;

									grant select on hepsusr.entry_decl_tax to htreader;

									grant select on hepsusr.entry_docu to htreader;

									grant select on hepsusr.entry_fees to htreader;

									grant select on hepsusr.entry_goods_tax to htreader;

									grant select on hepsusr.entry_head to htreader;

									grant select on hepsusr.entry_list to htreader;

									grant select on hepsusr.entry_workflow to htreader;

									grant select on hepsusr.iq_append to htreader;

									grant select on hepsusr.iq_cert to htreader;

									grant select on hepsusr.sub_swap to htreader;

									grant select on hepsusr.vin_list to htreader;

第五步：在新账号端创建同位显示表

因为新创建的只读账号，tables栏中显示为空，我们需要在pl/sql显示栏中为新账号登录界面添加显示同位元素，如下：

				?

									--在原账号hepsusr端执行，获取需要显示的表名称

									select 'create or replace synonym htreader.'||object_name|| ' for ' ||owner|| '.'||object_name||';'

									from dba_objects

									where owner in ('hepsusr')

									and object_type='table'

第六步：查询结果在新账号端执行

				?

									在只读账号htreader端执行：添加显示各个表信息；在sysnonym目录下，tables目录下无显示

									create or replace synonym htreader.vin_list for hepsusr.vin_list;

									create or replace synonym htreader.sub_swap for hepsusr.sub_swap;

									create or replace synonym htreader.sub_message_info for hepsusr.sub_message_info;

									create or replace synonym htreader.iq_cert for hepsusr.iq_cert;

									create or replace synonym htreader.iq_append for hepsusr.iq_append;

									create or replace synonym htreader.entry_workflow for hepsusr.entry_workflow;

									create or replace synonym htreader.entry_list for hepsusr.entry_list;

									create or replace synonym htreader.entry_head for hepsusr.entry_head;

									create or replace synonym htreader.entry_goods_tax for hepsusr.entry_goods_tax;

									create or replace synonym htreader.entry_fees for hepsusr.entry_fees;

									create or replace synonym htreader.entry_docu for hepsusr.entry_docu;

									create or replace synonym htreader.entry_decl_tax for hepsusr.entry_decl_tax;

									create or replace synonym htreader.entry_container for hepsusr.entry_container;

									create or replace synonym htreader.entry_cert_relation for hepsusr.entry_cert_relation;

									create or replace synonym htreader.entry_cert for hepsusr.entry_cert;

第七步：执行完成之后登录新账号，查看结果

新账号可以查询原账号的所有表结构，但是无法执行增删改相关操作

第八步：执行删除、修改sql语句测试

附录：oracle查询账号及权限详细语句

				?

									1.查看所有用户：

									select * from dba_users;

									select * from all_users;

									select * from user_users;

									2.查看用户或角色系统权限(直接赋值给用户或角色的系统权限)：

									select * from dba_sys_privs;

									select * from user_sys_privs;

									3.查看角色(只能查看登陆用户拥有的角色)所包含的权限

									sql>select * from role_sys_privs;

									4.查看用户对象权限：

									select * from dba_tab_privs;

									select * from all_tab_privs;

									select * from user_tab_privs;

									5.查看所有角色：

									select * from dba_roles;

									6.查看用户或角色所拥有的角色：

									select * from dba_role_privs;

									select * from user_role_privs;
