http://dbajun.iteye.com/blog/135331

1.查看所有用戶：
  select * from dba_users;
  select * from all_users;
  select * from user_users;

2.查看用戶或角色系統權限(直接賦值給用戶或角色的系統權限)：
  select * from dba_sys_privs;
  select * from user_sys_privs;

 

3.查看角色(只能查看登陸用戶擁有的角色)所包含的權限

sql>select * from role_sys_privs;

4.查看用戶對象權限：
  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.查看用戶或角色所擁有的角色：
  select * from dba_role_privs;
  select * from user_role_privs;

 

7.查看哪些用戶有sysdba或sysoper系統權限(查詢時需要相應權限)

select * from V$PWFILE_USERS

 

 

注意：

1、以下語句可以查看Oracle提供的系統權限

select name from sys.system_privilege_map

 

2、查看一個用戶的所有系統權限(包含角色的系統權限)

select privilege from dba_sys_privs where grantee='DATAUSER'
union
select privilege from dba_sys_privs where grantee in (select granted_role from dba_role_privs where grantee='DATAUSER' );
