DMX Query, the most influential variable

Question

Yours sincerely.
I'm doing work of data mining using decision trees, and I have the expected result: Predicted probability of dropping out, however I would like the result, by DMX query, throw me the most influential variable in the above probability .
For example if Marco, has a 90% chance of dropping out, tell me what was the most influential variable for this probability, which can be Sex, Age, City, etc..
I have in my data mining model, named Tree, variables such as sex, age, marital status, district, etc., and my view of the data, Vista_Datos, fields such as customer name, phone, email, Prov.; so my query resulted DMX follows.
Select
   (T. [CustomerName]) as [Customer]
  (T. [date]) as [Date of Appointment]
  t. [Department],
  t. [Province]
  t. [District]
  (T. [address]) as [Address],
  (T. [telephone]) as [Phone Fixed]
  (T. [Cell_Phone]) as [Cell Phone]
  (T. [email]) as [E],
  PredictProbability ([Tree]. [Desertion], 0) * 100 as [Probability of Defection]
From
  [Tree]
PREDICTION JOIN
  OPENQUERY ([Source Mining]
    'SELECT
      [CustomerName]
      [Date],
      [Department],
      [Province]
      [District]
      [Street address]
      [telephone]
      [Cell_Phone]
      [Email]
    FROM
      [Dbo]. [Vista_Datos]
    ') AS t
ON
  [Tree]. [Department] = t. [Department] AND
  [Tree]. [Province] = t. [Province] AND
  [Tree]. [District] = t. [District] AND
where (PredictProbability ([Tree]. [Desertion], 0) * 100)> 50
I need to modify the query to get the most influential variable in the prediction result.
I hope I have been clear so they can help me.
Thank you for your attention.
  

Answer 1

select * from [Model_Name].content
returns you all the information about the model (all the nodes in the tree).
select NODE_UNIQUE_NAME from [Model_Name].content where NODE_TYPE=2
returns NODE_UNIQUE_NAME of the root node. If you want to find all children of the root node (all the first splits) you can execute query like
select * from [Model_Name].content where [PARENT_UNIQUE_NAME]='000000004'
where '000000004' is NODE_UNIQUE_NAME of the root node.
