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
注意:
1、以下语句可以查看Oracle提供的系统权限
select name from sys.system_privilege_map
2、查看一个用户的所有系统权限(包含角色的系统权限)
Sql代码
- 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‘ );
