如何建立只读权限oracle帐户

1. 建立角色 
   CREATE ROLE SELECT_ROLE 
   2.给角色分配权限 
   grant SELECT ANY DICTIONARY to SELECT_ROLE; 
   grant SELECT ANY TABLE to SELECT_ROLE; 
   grant SELECT ANY TRANSACTION to SELECT_ROLE; 
   grant SELECT ANY SEQUENCE to SELECT_ROLE; 
   3.把角色赋予指定帐户 
   grant SELECT_ROLE to user; 
   4.删除角色 
   drop role SELECT_ROLE;

   五、建立用户

   create user db_hxzg identified by 123 

   六、赋给帐号链接权限

   grant connect, resource to aaaa;
   

   grant create session to aaaa;
   

7.检查角色的权限 
select * from dba_sys_privs where grantee=’SELECT_ROLE’

测试权限的时候须要加上用户的对象例如 
select count(*) from hr.ex_user;
