How to query Classification details in Windchill 10.2

Hi All,

I would like to retrieve  Classiffication  attribute details using

Tables:

1.  Part (wt.part.WTPart)

2.  Classification Node (wt.csm.navigation.ClassificationNode)

3.  Reference Value (wt.iba.value. ReferenceValue)

Joins:

1.  Reference Value- IBAHolder Reference- Part

2.  Reference Value- IBAReferenceable Reference- Classification Node

It gives "no rows selected" still attributes are available.

Does same query works in Windchill 10.2?
