本站中文解释

ALL_COL_PRIVS视图用于显示当前用户或其它用户拥有的表或视图的列权限,其主要由如下6个字段组成:

GRANTEE: 拥有权限的用户或程序
TABLE_SCHEMA: 表或视图所属的Schema
TABLE_NAME: 表或视图名
COLUMN_NAME: 列名
PRIVILEGE: 权限类型
IS_GRANTABLE: 用户是否可将权限授予其它用户

使用ALL_COL_PRIVS视图可以很容易查询指定用户(GRANTEE)拥有某张表(TABLE_NAME)中列(COLUMN_NAME)的权限(PRIVILEGE),以及是否可将权限授予其他用户(IS_GRANTABLE)。例如:

查询当前登录用户拥有表 USERS 中所有列的权限
SELECT GRANTEE, TABLE_SCHEMA, TABLE_NAME, COLUMN_NAME, PRIVILEGE, IS_GRANTABLE
FROM ALL_COL_PRIVS
WHERE GRANTEE = USER AND TABLE_NAME = ‘USERS’;
