Vinny, Thanks a lot for responding to my question and it was really helpful. I appreciate it. Thanks once again. I was using JDO query cursors mentioned in the app engine documentation and hence i had the problem however i have not tried whether the same "EXQ" is being produced in the app enging datastore queries. Kindly let me know if i can check the same condition like i check for null and empty even for datastore queries too if that happens for me once i try with it.
Thanks a lot for your support, Srikanth On Thu, Nov 7, 2013 at 11:18 AM, Vinny P <[email protected]> wrote: > On Wed, Nov 6, 2013 at 7:01 AM, srk <[email protected]> > wrote: > > I was working with query cursors in gae and found a weird cursor value >> named 'ExQ' retured by the query when there were no additional records.
