关于Hibernate支持原生sql的写法

StringBuffer sql=new StringBuffer("SELECT * FROM edu_video");
        sql.append(" WHERE videoPath = '" + videoPath + "'");
        Query query =  getSession().createSQLQuery(sql.toString());
        query.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP);

或

StringBuffer sql=new StringBuffer("SELECT * FROM edu_video");
        sql.append(" WHERE videoPath = '" + videoPath + "'");
        Query query =  getSession().createSQLQuery(sql.toString());
        query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);

其下为遍历

if(query.list() != null && query.list().size() > 0) {
            Map map = (Map) query.list().get(0);
            return map;
            
        }

Hibernate执行sql 修改

String sql="update EduVideo video set video.online="+online+" where video.videoPath='"+videoPath+"'";
        Query query = getSession().createQuery(sql);
        query.executeUpdate();

        if(list.isEmpty()){  
            return null;  
        }else{
