Hello, I would like to use the criteria API to implement a query builder that would build complex search queries from simple predicates. I thought I could use HQL for expressing predicates like "User.Supervisor.Name = 'John Smith'" and then convert such predicates to criteria (by parsing them with Expression.Sql) and join them with Expression.And/Expression.Or. But it appears that Expression.Sql will only handle raw SQL and not HQL (I don't know why I thought it will parse HQL). So, my question is if there's a way to parse HQL expressions and convert them to criteria objects?
