With Oracle Database it is possible to create something similar to Teradata&#8217;s sparse indexes?
Since the question is an interesting one, I decided to write this short post.
First of all, I have to say that such a feature is not supported by the CREATE INDEX statement [...]]]></description>

To make sure that the tables are equi-partitioned, as of Oracle Database 11g reference partitioning can be used. In fact, per definition, with reference partitioning all “related” tables have exactly the same partitioning schema. If [...]]]></description>
