Question

I am trying to make a query as usual but this time I need three conditions in my query. So I have written a code and the query is something like this:

Query query = pm.newQuery(LokationsEntry.class, " personalgroup == 1 && openningtime < now && closingtime > now");
query.declareParameters("java.util.Date now");

entries = (List<LokationsEntry>) query.execute(now);

Now is a date parameter.

The problem is that if I remove one of the date comparisons it works fine. But it gives me this error if I use both date comparisons. I need to query so that the time is between closing and opening times. Do you know how to solve this puzzle?

The problem is because of the documented limitation of google app engine unsolvable through query. You have to make the second filtering with your own code.
