If you have the privileges, you can use the ALL_INDEXES or USER_INDEXES views. The query would be:
如果您有权限,您可以使用 ALL_INDEXES 或 USER_INDEXES 视图。查询将是:
SELECT *
FROM all_indexes
WHERE table_name = 'COUNTRY';
If you want some information on the columns included in the index, you can select those from ALL_IND_COLUMNS. Documentation regarding these views can be found here Static Data Dictionary Views: ALL_ALL_TABLES to ALL_MVIEWS
如果您需要有关索引中包含的列的一些信息,您可以从 ALL_IND_COLUMNS 中选择这些信息。可以在此处找到有关这些视图的文档静态数据字典视图:ALL_ALL_TABLES 到 ALL_MVIEWS
