Query based change notifications

Question

Hi,
am trying to use the query based notifications, but it seems to switch over to the object based notification for some reason. My environment is Oracle 11.2 ( I believe you need 11.1 or above for query based to work) and I have a select statement which retrieves a column which is of type NUMBER. (Again here my understanding is that only varchar2 and number columns work). I seem to get every change notification on the table and not just my flltered dataset
As an example I've created a sample table called test_db_notification with a single column of type NUMBER.
desc test_db_notification
Name Null Type
COLUMN1 NUMBER
Added two entries in there as follows:
SELECT rowid,column1 FROM test_db_notification;
ROWID                          COLUMN1
AAAERnAAKAAEurNAAI                54
AAAERnAAKAAEurPAAA                63           
Here's my code to register for notification:
     OracleCommand cmdObj = connObj.CreateCommand();
cmdObj.CommandText = " SELECT column1 FROM testdb_notification where column1 = 63";
_dep = new OracleDependency(_cmdObj);
_dep.QueryBasedNotification = true;
_dep.OnChange += new OnChangeEventHandler(_dep_OnChange);
_cmdObj.Notification.IsNotifiedOnce = false;
_cmdObj.AddRowid = true;
_cmdObj.ExecuteNonQuery();
When I register and change the value of column1 where the current value is 54, I get back a notification saying the ROWID for 54 has been updated.
I was expecting not to receive any notifications since my original query looks only at column1 = 63. Am I missing something here?

Hi,
This isnt related to the beta.
From the CQN docs..
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28424/adfns_cqn.htm#CHDIEJEI
You must be connected as a non-SYS user in order to create CQN registrations.
Hope it helps,
