                .setQuery(LoadContext.createQuery("insert into collegedata_college (college_id,college_name) VALUES (?,?)")
                        .setParameter("college_id", 01).setParameter("college_name","ram"));
                //.setParameter("college_name", college_name)
                //.setView("college.full");
