如何查看Oracle的用戶權(quán)限？

"ORACLE數(shù)據(jù)字典視圖的種類分別為：USER,ALL 和 DBA.

USER_*:有關(guān)用戶所擁有的對象信息，即用戶自己創(chuàng)建的對象信息

ALL_*:有關(guān)用戶可以訪問的對象的信息，即用戶自己創(chuàng)建的對象的信息加上

其他用戶創(chuàng)建的對象但該用戶有權(quán)訪問的信息

DBA_*:有關(guān)整個數(shù)據(jù)庫中對象的信息

(這里的*可以為TABLES,INDEXES,OBJECTS,USERS等。)

1、查看所有用戶

SELECT * from dba_user;

select * from all_users;

select * from user_users;

2、查看用戶系統(tǒng)權(quán)限

select * from dba_sys_privs;

select * from all_sys_privs;

select * from user_sys_privs;

3、查看用戶對象權(quán)限

select * from dba_tab_privs;

select * from all_tab_privs;

select * from user_tab_privs;

4、查看所有角色

select * from dba_roles;

5、查看用戶所擁有的角色

select * from dba_role_privs;

select * from user_role_privs;

6、查看當(dāng)前用戶的缺省表空間

select username,default_tablespace from user_users;

7、查看某個角色的具體權(quán)限

如grant connect,RESOURCE,create session,create view to TEST;

8、查看RESOURCE具有那些權(quán)限

用SELECT * FROM DBA_SYS_PRIVS WHERE GRANTEE='RESOURCE
