I am using Criteria API. I want to use the Aggregate Functions like Avg(),count() etc in the where clause i know its available through Projections but projections used as the slect part of the query i want to use these functions in where clause like criteria.add(Restriction.eq(Projections.count("emp"),5)); Is there any way to do that. if the problem is not clear lets say i have two tables Employee and Address and the relation between is one to many Employee have multiple Addresses so i want to retrieve the employee who have 5 or more Addresses. Code is like that. Criteria criteria = session.createCriteria(Employee.class,"emp"); | criteria.setFetchMode("addresses",FetchMode.EAGER); | ProjectionList projList = Projections.projectionList(); | projList.add(Projections.count("emp.addresses"),"NoOfOpp"); | criteria.setProjection(projList); | criteria.add((Restrictions.ge("NoOfOpp",6))); | List list=criteria.list(); | | When i execute this it gives me NoOfOpp invalid identifier is any other way round to accomplish the task.
