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;
