count(*) and groupby - Projections

[JayaSiji Gopal]

I have a query

  select column1, count(*) from tableName where .... groupby column1  

I am trying to use Hibernate detached criteria and have the following code:

   
   
DetachedCriteria projectionsCriteria = DetachedCriteria.forClass(1.class);
		//projectionsCriteria.createAlias("articleAttributes", "ar");
		projectionsCriteria.add(Restrictions.eq(...));
		projectionsCriteria.add(Restrictions.in(...));
		projectionsCriteria.add(Restrictions.in(...));
		projectionsCriteria.setProjection(Projections.groupProperty("id.value"));
		HashMap<String, Object> hmTopicsCount = (HashMap<String, Object>)getHibernateTemplate().findByCriteria(projectionsCriteria)

This generates the above query with count(*). What should i add to get the count(*) in the query?
I tried projectionsCriteria.setProjection(Projections.count("column1")); and
projectionsCriteria.setProjection(Projections.rowCount());

that does not work. Any ideas?
