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

ALL_ANALYTIC_VIEW_DIM_ATTRS视图是Oracle维度分析中数据仓库模式中概念性模型的补充;它允许查询电子数据仓库中维度的属性结构。该视图的每一行描述一个维度列属性及其特定属性的完整活动图。

使用ALL_ANALYTIC_VIEW_DIM_ATTRS要如何使用：

1.选择视图：SELECT * FROM all_analytic_view_dim_attrs;

2.通过视图的列查询：SELECT code_seq, attr_value, attr_name FROM all_analytic_view_dim_attrs WHERE dim_name = ‘gender’;

3.在查询语句中使用WHERE子句来限定要检索的维度，例如WHERE dim_name = ‘gender’;

4.使用ORDER BY子句来按照你想要的顺序排列维度属性，例如ORDER BY code_seq DESC;

5.使用GROUP BY子句来聚集维度属性，例如GROUP BY attr_name;

6.使用HAVING子句在将要聚集的维度中进一步指定要检索的数据，例如HAVING attr_name LIKE ‘%Female’

ALL_ANALYTIC_VIEW_DIM_ATTRS describes the attributes of the attribute dimensions in the analytic views accessible to the current user.
