本站中文解释
是 Oracle 中一种视图，它是用于分析大型工作负载的、可快速查找、层次排序和汇总数据的实用程序，在 Oracle 做大量的负载时可有效的实现数据的层次加载。
使用方法:
1. 使用 SQL 语句创建 USER_ANALYTIC_VIEW_HIER_CLS_AE 视图：
CREATE OR REPLACE VIEW USER_ANALYTIC_VIEW_HIER_CLS_AE AS
SELECT col1,…. coln
FROM some_table;
2. 通过 USER_ANALYTIC_VIEW_HIER_CLS_AE 视图查看列：
SELECT col1,…. coln
FROM USER_ANALYTIC_VIEW_HIER_CLS_AE;
3. 使用 USER_ANALYTIC_VIEW_HIER_CLS_AE 视图进行层次加载：
SELECT col1,…. coln
FROM USER_ANALYTIC_VIEW_HIER_CLS_AE
WHERE start_date >= TO_DATE(‘2030-03-01’, ‘YYYY-MM-DD’);
官方英文解释
USER_ANALYTIC_VIEW_HIER_CLS_AE describes the classifications of the hierarchies in the analytic views (across all editions) owned by the current user. Its columns (except for OWNER) are the same as those in ALL_ANALYTIC_VIEW_HIER_CLS_AE.
Note:
This view is available starting with Oracle Database release 21c, version 21.5.
