Aggregate function in where clause (Criteria API)

shouab · **Posted:** Mon Sep 04, 2006 5:48 am

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.

Code:

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.
