0 - 3 of 3 tags for oracle 11g

When using a Java Stored Procedure from within the Oracle 11g database, an attempt to open a connection to Teradata using the JDBC driver version 14 throws the following error.
Exception in thread "Root Thread" java.lang.NullPointerException

Hi all,
We are migrating from oracle to teradata, and got stuck with dense_rank function, please any suggestions would be appreciate. 
Here is our query in oracle: 
 

select 

dense_rank() OVER (ORDER BY STATE) AS STATE_KEY, 

COALESCE(columnA, 'Other')

from  tableA
