REASSIGN OWNED

REASSIGN OWNED — 更改由数据库角色拥有的数据库对象的归属

REASSIGN OWNED — change the ownership of database objects owned by a database role

Synopsis

REASSIGN OWNED BY { old_role | CURRENT_ROLE | CURRENT_USER | SESSION_USER } [, ...]
               TO { new_role | CURRENT_ROLE | CURRENT_USER | SESSION_USER }

Description

REASSIGN OWNED 指示系统将由 old_roles 中的任何一个 new_role 拥有的数据库对象的归属更改为 new_role 。

REASSIGN OWNED instructs the system to change the ownership of database objects owned by any of the old_roles to new_role.

Parameters

old_role
- The name of a role. The ownership of all the objects within the current database, and of all shared objects (databases, tablespaces), owned by this role will be reassigned to new_role.
new_role
- The name of the role that will be made the new owner of the affected objects.

Notes

REASSIGN OWNED 通常用于准备移除一个或多个角色。由于 REASSIGN OWNED 不会影响其他数据库中的对象，所以通常有必要在包含要移除的角色拥有的对象的每个数据库中执行此命令。

REASSIGN OWNED is often used to prepare for the removal of one or more roles. Because REASSIGN OWNED does not affect objects within other databases, it is usually necessary to execute this command in each database that contains objects owned by a role that is to be removed.

REASSIGN OWNED 需要源角色和目标角色中都有成员身份。

REASSIGN OWNED requires membership on both the source role(s) and the target role.

DROP OWNED 命令是一个替代命令，它仅删除一个或多个角色拥有的所有数据库对象。

The DROP OWNED command is an alternative that simply drops all the database objects owned by one or more roles.

REASSIGN OWNED 命令不会影响授予角色 old_roles 的权限，这是因为他们不拥有这些权限。同样地，它不会影响使用 ALTER DEFAULT PRIVILEGES 创建的默认权限。使用 DROP OWNED 撤销此类权限。

The REASSIGN OWNED command does not affect any privileges granted to the old_roles on objects that are not owned by them. Likewise, it does not affect default privileges created with ALTER DEFAULT PRIVILEGES. Use DROP OWNED to revoke such privileges.
