SqlQuery and result caching in Hibernate

Question

Hi!

I need to count records amount like this:

Query qry = session.createSQLQuery("SELECT count(id) FROM object_permission_role WHERE object_permission_id=?");

as well, I am using query cache true.

How can I cache my sqlquery that returns the count(id) until someone in the code updates/delete/add any row to object_permission_role table?
