Oracle 视图 ALL_ANALYTIC_VIEW_DIM_CLASS 官方解释，作用，如何使用详细说明

Oracle视图ALL_ANALYTIC_VIEW_DIM_CLASS用来获取所有大数据分析视图的维度和类别信息。它可以帮助开发者跟踪每个维度的维度类型、编号、名称、描述和状态等。

可以使用以下SQL语句检索ALL_ANALYTIC_VIEW_DIM_CLASS视图：
SELECT *
FROM ALL_ANALYTIC_VIEW_DIM_CLASS
WHERE analytic_view_name = ”;

其中，是您想检索的分析视图的名称。

通过ALL_ANALYTIC_VIEW_DIM_CLASS视图的查询，您还可以获取每个维度的所有子维度的细节：
SELECT *
FROM ALL_ANALYTIC_VIEW_DIM_CLASS
WHERE analytic_view_name = ”
AND parent_dim_id = ;

其中，是要检索子维度的父维度ID。

ALL_ANALYTIC_VIEW_DIM_CLASS视图可以帮助开发人员了解用于构建特定大数据分析视图的维度，并了解其具体结构和信息。

ALL_ANALYTIC_VIEW_DIM_CLASS describes the classifications of the attribute dimensions in the analytic views accessible to the current user.
