Hi all i am using JDO and i want to count the number of entities so which is more efficient using a count quert, eg: select count (this) from User or key only query select id from User then get the count using resultList.size();
by the way , i know that the recommended way on appengine is to precompute but this cannot be done in my case thanks Joe -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
