Is the same.
Code:
select count(a.name), a.createdate from MyClass a group by a.createdate

However I don't know how to insert a constant in the select clause, but I think that 'a' can be managed at code level

Why you need the constant in the select clause?

If I have understood your problem you can load only the results from the hql and then concatenating the strings:
Code:
String[] results = null;
           
Query q = session.createQuery("select count(a.name), a.createdate from MyClass a group by a.createdate");
List list = q.list();
           
results = new String[list.size()];
for(int i = 0; i < list.size(); i++) {
    Object[] row = (Object[])list.get(i);
    results[i] = row[0] + "a" + row[1];
}
