网络编程 Oracle 视图 ALL_ATTRIBUTE_DIM_JN_PTHS_AE 官方解释，作用，如何使用详细说明 10-15

Oracle视图ALL_ATTRIBUTE_DIM_JN_PTHS_AE是一个用于检索有关维度主路径属性的视图。

它能够检索属性的名称、位置、顺序、等参数，以及属性值列表。这些参数将有助于确定维度主路径的全部属性信息。

此外，视图中还包含了以属性标识开头的”列定义”，可以提供有关属性值的更多信息，包括可否为空、最小值、最大值等。

可以使用此视图向维度结构添加主路径，或检索所有与现有维度定义相关的信息。可以使用SELECT语句检索此视图中的数据。例如，可以使用以下SELECT语句检索当前有效维度的属性的完整信息：

SELECT * FROM all_attribute_dim_jn_pths_ae WHERE dim_id = ‘ABC’ AND valid_flag = ‘Y’ ;
