If you create an alias, then create a criteria and join to another table, etc., it is only going to resolve {alias} to the root table that the alias was created for. hibernateCriteria.createCriteria("orderItems", "i", Criteria.LEFT_JOIN ).add( Restrictions.or(Restrictions.sqlRestriction("orderNo=?", orderNo, Hibernate.Long), Restrictions.sqlRestriction("{alias}.item_id in (SELECT item_id FROM items WHERE item_id = ?)", itemId, Hibernate.LONG) ) ); Lessons Learnt Blog: Criteria c = session.createCriteria(BaseTable.class, "base"); Criteria secondCriteria = c.createCriteria("secondTable","second", CriteriaSpecification.LEFT_JOIN); secondCriteria.add(Restrictions.sqlRestriction("{alias}.id = someCoolCondition"); From the Hibernate docs: List cats = sess.createCriteria(Cat.class) .createAlias("kittens", "kt") .createAlias("mate", "mt"...
