DatastoreService ds =
DatastoreServiceFactory.getDatastoreService();
Query query = new Query("Table1");
query.addFilter("cid", Query.FilterOperator.EQUAL, 1111l);
// was not very clear documented how dates are saved in DB
// query.addFilter("ctime",
Query.FilterOperator.GREATER_THAN_OR_EQUAL, "DATE(2009, 12, 1)");
// query.addFilter("ctime",
Query.FilterOperator.GREATER_THAN_OR_EQUAL, new Date(2009, 12, 1));
query.addFilter("ctime",
Query.FilterOperator.GREATER_THAN_OR_EQUAL,
new Date(2009, 12, 1).getTime());
query.addSort("ctime");
query.setKeysOnly();
FetchOptions options = FetchOptions.Builder.withLimit(1000);
PreparedQuery p1 = ds.prepare(query);
Iterable it = p1.asIterable(options);
I hope it will help someone.
