PredictNodeId (DMX)

[!INCLUDEssas]

Returns the Node_ID of the node to which the case is classified.

Syntax

  
PredictNodeId(<scalar column reference>)  

Applies To

A scalar column.

Return Type

<scalar expression>

Examples

The following example returns whether the specified individual is likely to buy a bicycle, and also returns the nodeID of the node that they are most likely to be part of.

SELECT  
  [Bike Buyer],  
  PredictNodeId([Bike Buyer])  
From  
  [TM Decision Tree]  
NATURAL PREDICTION JOIN  
(SELECT 28 AS [Age],  
  '2-5 Miles' AS [Commute Distance],  
  'Graduate Degree' AS [Education],  
  0 AS [Number Cars Owned],  
  0 AS [Number Children At Home]) AS t  

You could then use the following statement to determine what is contained within the node:

SELECT   
  NODE_CAPTION   
FROM   
  [TM Decision Tree].CONTENT  
WHERE NODE_UNIQUE_NAME= '00000000100'
