I is very simple to add parameter to an HQL

Query query = session.createQuery("select u from UserLog u where u.userLogSerialno = " + "(select max(uu.userLogSerialno) from UserLog uu where uu.userId = :userId)").setParameter("userId", 15);

here i have hard coded 15 you can simply use variable instead of it

Simple example:

Integer id = 1;
Query query = session.createQuery("from Employee e where e.idEmployee=:id");
query.setParameter("id", id);
