I'm using Hibernate in an application where I have 2 main requirements:
1. I need to make a query in hql, wich I store in metadata (xdoclet) giving it a name
2. I need to use this query by name AND filter it afterwards (let the final user apply additional filters to the original query results)

I would like to do something like:
Query q = getSession().getNamedQuery(queryName);
q.addCriteria(Expression.like(propertyName, propertyValue));
result = q.list();

I've tried filters, but they don't allow to filter query results, but persistent collections.

Is it possible to use the Criteria API against a query stored by name in HQL? In such case, how? If not, should I filter the query modifying the HQL string adding and clauses by hand? Is there any other aproach I'm missing?

Thanks in advance,
Jordi

Class filters do allow you to filter query results. Section 17 of the ref docs explain it.

The only other way to filter results before executing the HQL query is to build the HQL query dynamically. You can do this even if you've created a named query in xdoclet (or a mapping file) by getting the named query, calling getQueryString on it, adding to the string as necessary, and creating a new query from that string.

Your only other option is to filter the results, in code.

Since I'm usinig version 2.1.8 I have only the 2 last options, but they are absolutely vaild.

Many thanks!
