Oracle视图ALL_ATTRIBUTE_DIMENSIONS用来获取表、视图、或物化视图中的属性维度信息。ALL_ATTRIBUTE_DIMENSIONS视图包含了模式、表、视图、或是物化视图中维度名、外部属性维度个数、外部属性维度类型等信息。

使用ALL_ATTRIBUTE_DIMENSIONS视图，可以获取某特定模式下的表或视图中的某个特定的外部属性维度信息。而使用该视图，可以获取表中的属性维度个数，以及属性维度的类型。

下面给出一个示例，查询名为“EMP”的表的外部属性维度的信息，可以使用下列SQL语句：

SELECT OWNER, TABLE_NAME, COLUMN_NAME, ATTRB_NAME, ATTRB_TYPE
FROM ALL_ATTRIBUTE_DIMENSIONS
WHERE OWNER = ‘SCOTT’ AND TABLE_NAME = ‘EMP’;
