Sorry for the late reply Martin, but even if I add the datetime field in here,and order by the datetime field , wont I get the data in ascending order . However I did what you had suggested , But i still am able to retrive the data in ascending order rather than descending. Could there be any other method .. (A quick recap--> I am trying to get the data ordered in descending order from the dbase. It can be done by using a tilde , but the GAE seems to ignore the tilde all together.. Please help)
