Oracle 视图 ALL_ATTRIBUTE_DIM_TABLES 官方解释,作用,如何使用详细说明
本站中文解释
all_attribute_dim_Tables指的是Oracle数仓中的属性(Attribute)维表。此视图将所有已定义的维表列出,包括一些高级功能,如共享智能维表(shared intelligence dimensions)和多标识维表(multi- identifier dimensions)。
通过all_attribute_dim_tables视图,用户可以查看指定维表的内容,以及具有某种特定属性的维表(如拥有特定形态(Shape)的表)。通常,“SHAPE”列用于记录复杂表中属性维表的形状,可以使用它来查询比对应关系维表更复杂的表。
使用all_attribute_dim_Tables的步骤:
1.登录得到Oracle数据仓库系统;
2.运行select语句查询all_attribute_dim_tables视图;
3.如果想查询拥有特定形态(Shape)的表,可以进一步替上面的查询加入查询条件:如shape like ‘ Flat%”;
4.运行查询结果,查看符合条件的结果列表。
