ALL_ANALYTIC_VIEW_KEYS_AE视图是Oracle数据库11gR2以后提供的一种视图，主要用于查询和管理Anrolitic Views的元数据信息，使用这个视图可以获取对象的详细信息，包括对象的字段，滚定窗口特性，分组特性，以及与该视图相关联的特殊索引(specialized indexes)和特殊并行化设置(specialized parallel settings)。

要使用这个视图，首先需要获取连接时所在用户的两个信息：用户名和命名空间，一般用下面这个SQL语句来获取：

SELECT * FROM ALL_ANALYTIC_VIEW_KEYS_AE WHERE NAMESPACE = ‘your_space’ ORDER BY NAME;
