Thanks DataNucleus team and Toby. Sorry, but I have some more questions
1. How do I delete a particular table dynamically? would just unloading the class do it? Iin that case, what if there are changes to the dynamic table, i.e. column addition/dropping, wouldnt that require unloading the class and hence deletion of table? 2. I am going through the Queries and Indexes section in the documentation at http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html This section says that inequality operators are allowed only one property. Is anybody handling a situation where there are multiple properties with inequality operators? If yes, how have you done it?
