I was just going off on a tangent. AFAIK, what you describe cannot be done, unless somebody comes and builds it. Wouldn't hold my breath though, HQL was not built for in-memory execution.
I'd rather go look for a way to serialize in-memory LINQ queries. http://stackoverflow.com/questions/4036489/what-is-the-easiest-way-to-save-a-linq-query-for-later-use Also, Silverlight RIA toolkit has code that does that. For remote invocation, not storage, but hey... problems: - in RIA toolkit, serialization (client) and deserialization (server) use similar, but different types. - if you compile an IQueryable expression, it will compile to the IQueryable and Queryable extension methods. you'd need to replace that with IEnumerable and Enumerable extension methods so that they actually do the work instead of just creating expression trees again. Other stuff might be available. Tell us if you find a way!
