Microsoft Decision Trees: support cases for a specific node

I'm using Microsoft Deci开发者_JAVA技巧sion Trees in Microsoft Analysis Services Data Mining, and need to show the historical data (the support cases from the training data used to train the decision tree) for a given leaf node in my mining model. Is there a way to access those records directly based on the NodeID using a DMX query, or is the only way to get the NODE_DESCRIPTION for the node, replace not = with <> and execute a query against my live database with that as my WHERE clause?

SELECT * FROM [ModelName].Cases
