[转]如何查看oracle用户具有的权限和角色

本文转自:https://www.cnblogs.com/qlqwjy/p/8404959.html

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' );
