Hello, i am using Hibernate to map a Hashmap object . the key of the Hashmap is a string, the value of it is a customer object. I map the Hashmap object to database with the lazy mode.
But when i invoke the size() method of the hashmap. Hibernate will read all the customer object' data from the database and save to the session. the time will be delay.
I only want to know the size of the Hashmap and don't want the customer object. Help ????
