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;
7.查看哪些用户有sysdba或sysoper系统权限(查询时需要相应权限)
select * from V$PWFILE_USERS
比如我要查看用户 wzsb的拥有的权限：
SQL> select * from dba_sys_privs where grantee='WZSB';
GRANTEE PRIVILEGE ADMIN_OPTION
------------------------------ ---------------------------------------- ------------
WZSB CREATE TRIGGER NO
WZSB UNLIMITED TABLESPACE NO
比如我要查看用户 wzsb的拥有的角色：
SQL> select * from dba_role_privs where grantee='WZSB';
GRANTEE GRANTED_ROLE ADMIN_OPTION DEFAULT_ROLE
------------------------------ ------------------------------ ------------ ------------
WZSB DBA NO YES
查看一个用户所有的权限及角色
select privilege from dba_sys_privs where grantee='WZSB'
union
select privilege from dba_sys_privs where grantee in
(select granted_role from dba_role_privs where grantee='WZSB' );
