not able to create data set using netezza as data source - always getting invalid fetch count

Hi,

I am using bi Publisher (11.1.1.6.2).

Trying to get connected to netezza db through bip.

Step used:

Created jdbc source- 

selected 'other' from drop down

driver class : org.netezza.Driver

Connection sting: jdbc:odbc:<ODBC_NAME>

using username/password

getting 'conneted successfully.

Created data model using above created data source.

Now when i m craeting data set using sql query from drop down, always i m getting ERROR ' Invalid fetch size.

(very strange getting invalid fetch size for 'select 1 from _v_dual' too)

Though  when i m using 'obi analysis' from drop down to create data set it works fine.
