1. 用户操作:
创建:
- CREATE USER user
- IDENTIFIED {BY password | EXTERNALLY}
- [DEFAULT TABLESPACE tablespace]
- [TEMPORARY TABLESPACE tablespace]
- [QUOTA {integer [K|M] | UNLIMITED} ON tablespace]
- [PROFILE profile]
修改:
- ALTER USER user
- [IDENTIFIED {BY password | EXTERNALLY}]
- [DEFAULT TABLESPACE tablespace]
- [TEMPORARY TABLESPACE tablespace]
- [QUOTA {integer [K|M] | UNLIMITED} ON tablespace]
- [PROFILE profile]
- [DEFAULT ROLE { role [, role] ...
- | ALL [EXCEPT role [, role] ...] | NONE}]
删除:
- DROP USER user_name [CASCADE]
授权,撤销权限:
- GRANT role TO user [WITH ADMIN OPTION]
-
- REVOKE role FROM user
系统允许 赋于整个系统的权限给用户,角色等:
- GRANT system_privilege TO {user_name | role | PUBLIC}
- [WITH ADMIN OPTION]
如果使用了WITH ADMIN OPTION 选项就允许拥有该权限的人将该权限应用给其它
的用户。
你可以使用下边的GRANT 语句来对其它用户授权访问你的表
- GRANT {object_priv | ALL [PRIVILEGES]} [ (column
- [, column]...) ]
- [, {object_priv | ALL [PRIVILEGES]} [ (column
- [, column] ...) ] ] ...
- ON [schema.]object
- TO {user | role | PUBLIC} [, {user | role | PUBLIC}] ...
- [WITH GRANT OPTION]
如果你想取消对某个对象对于某人的授权你可以使用REVOKE 语句语法如下
- REVOKE {object_priv | ALL [PRIVILEGES]}
- [, {object_priv | ALL [PRIVILEGES]} ]
- ON [schema.]object
- FROM {user | role | PUBLIC} [, {user | role | PUBLIC}]
- [CASCADE CONSTRAINTS]
