Design Criteria Building optimization must be followed by design criteria; these design criteria are given by the corresponding code. With the aim to determine the optimization criteria I personally have chosen the IBC 2013 Code with the corresponding related codes, such as ACI 318 and ASCE-7, concrete and load codes. Firstly we should determine the basic requirements for a high-rise building with shear wall structure and deep foundation as a foundation system, being this kind of building the objective of the study in situ. ?Building use and occupancy: (CHAPTER 3)Residential group R-2, residential occupancies containing sleeping units or more than two dwelling units where the occupants are primarily permanent in nature, including: Apartment houses, Boarding houses (non-transient), Convents, Dormitories, Fraternities and sororities, Hotels (non-transient), I Live/work units, Monasteries, Motels (non-transient), Vacation timeshare properties. ?Requirements based on occupancy:(CHAPTER 4) 1. For buildings not greater than 420 feet (128 m) in building height, the fire-resistance rating of the building elements in Type IA construction shall be permitted to be reduced to the minimum fire-resistance ratings for the building elements in Type IB. 2. In other than Group F-1, M and S-1 occupancies, the fire-resistance rating of the building elements in Type IB construction shall be permitted to be reduced to the fire-resistance ratings in Type IIA. 3.

One point is clear that different issues have different objective criteria. For example, criteria of price talking will include factors of cost, market situation, depreciation, price competition and other necessary factors. In other negotiations, exper ts’ opinions, international conventions and norms and legal documents will all serve as objective criteria. 为解决本人衣服无人洗，饭菜无人做，花钱无节制，生活无压力的现状，本人新引进 一招商项目，将于2020年02月20(26)日17时30分举行盛大的庆典活动，请亲朋好友准时参加! In the Sino—US negotiation on China’s accession into WTO, the two parties disputed over China’s developing country status. US took the position that China should be treated as a developed country. To back US stance, American negotiators cited China’s growing exports and large foreign reserve holdings. They a rgued that in developing countries China’s sophisticated technology in launching and retrieving satellites had no parallel. One American negotiator even compared the situation in China with that in India and some African countries. He said when he opened the door of a family in a poorest area randomly chosen by the Chinese government and asked the people if they had their breakfast, he was told they did, and he went on asking if lunch and supper were guaranteed, the answer was yes. However he had a very different story in some African countries and even in some areas in India. People there had little food for breakfast, not mention lunch and supper. The two countries insisted on their own standards and it was hard to bridge the discrepancy. Here the focus is which criterion to apply to for resolving the dispute. In fact there is a ready criterion provided by the World Bank, which is measured by per capita GNP. According to the World Bank’s standard, countries whose per capita GNP below $785 (1996) are the poorest countries. China’s per capita GNP in 1997 was $750, which is among the poorest countries. 甲方聘用乙方的月薪为_____元(含养老、医疗、住房公积金)。试用期满后，并经考 核合格，可根据平等协商的原则，签订正式劳动合同。
复合查询主要是处理，具有关联关系的两个实体怎样进行关联查询，比如User 实体对象与Addres实体对象具有一对多的关联关系，我们可以如下构造 符合查询： Criteria criteria=session.createCriteria(User.class); Criteria addcriteria=criteria.createCriteria(“addresses”);(1) addcriteria.add(Express.like(“address”,”%tianjin%”)); List list=criteria.list(); for(int i=0;i User user=(User)list.get(i); System.out.println(user.getName()+”\n”); Set addresses=user.getAddresses(); Iterator it=addresses.iterator(); while(it.hasNext(){ Address address=(Address)it.next(); Syste m.out.println(address.getAddress()+”\n”); } } 当执行到了（1）处时，表明要针对User对象的addresses属性添加新的查询条件，因此当执行criteria.list()时，Hibernate会生成类似如下的SQL语句： Select * from user inner join address on user.id=address.id where address.address like …%shanghai%?; 正如我们所见，我们可以通过向Criteria中添加保存关联对象的集合属性（addresses属性保存与User对象相关联的Address对象），来构造复合查询，在数据库一端是通过内连接查询来实现。 Hibernate QBC查询 QBC查询：
Criteria的使用总结 1、目前只遇到用于单表查询（多表查询期待中。。。） public Integer getqueryTamArchivesCount(String content, String fileNumber, String fileType, Date beginDate,Date endDate){ DetachedCriteria criteria = DetachedCriteria .forClass(TamArch.class); if (content != null && content.trim().length() > 0) { //模糊匹配 criteria.add(Restrictions.like("subject", "%" + content + "%")); } if (fileNumber != null && fileNumber.trim().length() > 0) { //相等 criteria.add(Restrictions.eq("archivesNo", fileNumber)); } if ("1".equals(fileType)) { //或者 criteria.add(Restrictions.or(Restrictions.eq("archivesStatus", "1"), Restrictions.eq("archivesStatus", "2"))); }else if("2".equals(fileType)){ criteria.add(Restrictions.eq("archivesStatus", "99")); } if(beginDate!=null&&endDate!=null){ //两者之间 criteria.add(Restrictions.between("issueDate",beginDate,endDate)); } //按日期降序排列 criteria.addOrder(Order.desc("inputDate")); return archDao.getRowCount(criteria) ; } 注意： ①对于日期有点bug，如果查询的日期为空，则查询不到数据。貌似日期为必填。 ②对于Restrictions.or：只能处理2种的情况 ③ //处理或情况（archivesStatus为2、3、99） criteria.add(Restrictions.in("archivesStatus", new Object[]{"2","3","99"}));
Criteria的几种查询方法使用 QBC常用限定方法 Restrictions.eq --> equal,等于. Restrictions.allEq --> 参数为Map对象,使用key/value进行多个等于的比对,相当于多个Restrictions.eq的效果 Restrictions.gt --> great-than > 大于 Restrictions.ge --> great-equal >= 大于等于 Restrictions.lt --> less-than, < 小于 Restrictions.le --> less-equal <= 小于等于 Restrictions.between --> 对应SQL的between子句 Restrictions.like --> 对应SQL的LIKE子句 Restrictions.in --> 对应SQL的in子句 Restrictions.and --> and 关系 Restrictions.or --> or 关系 Restrictions.isNull --> 判断属性是否为空,为空则返回true Restrictions.isNotNull --> 与isNull相反 Restrictions.sqlRestriction --> SQL限定的查询 Order.asc --> 根据传入的字段进行升序排序 Order.desc --> 根据传入的字段进行降序排序 MacthMode.EXACT :字符串精确匹配。相当于like …value? MathMode.ANYWHERE:字符串在中间匹配.相当于like …%value%? MathMode.START:字符串在最前端匹配位置.相当于:like …value%? MatchMode.END:字符串在最后端匹配.相当于:like …%value? 1.查询年龄在20-30之间的所有学生对象。 List list = session.createCriteria(Student.class) .add(Restrictions.between(“amout”,new BigDecimal(1),new BigDec imal(10)).list(); 2.查询S tudent名字开头有t的所有Student: List list = sesison.createCriteria(Student.class) .add(Restrictions.like(“name”,”t%”)).list(); 3.或者使用另一种查询Student名字开头有t的所有Student: List list = sesison.createCriteria(Student.class)
本文是对深入浅出Hibernate学习做的学习笔记，是个人在对深入浅出Hibernate学习中的一点认识和看法，下边是具体的内容。 本文是对深入浅出Hibernate学习做的学习笔记，是个人在对深入浅出Hibernate学习中的一点认识和看法，下边是具体的内容。 Criteria Query通过面向对象的设计，将数据查询条件封装为一个对象。简单来说，Criteria Query可以看作是传统SQL的对象化表示，如： 1.Criteria criteria=session.createCriteria(TUser.class); 2.criteria.add(Expression.eq("name","Erica")); 3.criteria.add(Expression.eq("sex",new Integer(1)); 这里的criteria实例本质上是对SQL“select * from t_user where name='Erica' and sex=1”的封装。Hibernate在运行期会根据Criteria中指定的查询条件生成相应的SQL语句。 Criteria查询表达式：Criteria本身只是一个容器，具体的查询条件要通过Criteria.add方法添加到Criteria实例中。 方法描述：Expression.eq 对应SQL “field=value”表达式 如：Expression.eq("name","Erica") 4.Expression.allEq 参数为一个Map对象，其中包含了多个属性-值对应关系。相当于多个 Expression.eq关系的叠加 5.Expression.gt 对应SQL“field>value”表达式 6.Expression.ge 对应SQL“field>=v alue”表达式 7.Expression.lt 对应SQL“field 最近在项目中使用Spring 和Hibernate 进行开发，有感于Criteria 比较好用，在查询方法设计上可以灵活的根据Criteria 的特点来方便地进行查询条件的组装。现在对Hibernate的Criteria 的用法进行总结： Hibernate 设计了CriteriaSpecification 作为Criteria 的父接口，下面提供了Criteria和DetachedCriteria 。 Criteria 和DetachedCriteria 的主要区别在于创建的形式不一样，Criteria 是在线的，所以它是由Hibernate Session 进行创建的；而DetachedCriteria 是离线的，创建时无需 Session，DetachedCriteria 提供了 2 个静态方法forClass(Class) 或forEntityName(Name) 进行DetachedCriteria 实例的创建。Spring 的框架提供了getHibernateTemplate ().findByCriteria(detachedCriteria) 方法可以很方便地根据DetachedCriteria 来返回查询结 果。 Criteria 和DetachedCriteria 均可使用Criterion 和Projection 设置查询条件。可以设 置FetchMode( 联合查询抓取的模式) ，设置排序方式。对于Criteria 还可以设置FlushModel （冲刷Session 的方式）和LockMode （数据库锁模式）。 下面对Criterion 和Projection 进行详细说明。 Criterion 是Criteria 的查询条件。Criteria 提供了add(Criterion criterion) 方法来 添加查询条件。 hibernate:Hibernate中Criteria的完整使用方法 疯狂代码 https://www.doczj.com/doc/cf2589201.html,/ ?:http:/https://www.doczj.com/doc/cf2589201.html,/Java/Article58225.html 最近在项目中使用 Spring 和 Hibernate 进行开发有感于 Criteria 比较好用在查询思路方法设计上可以灵活根据 Criteria 特点来方便地进行查询条件组装现在对 HibernateCriteria 使用方法进行整理总结: Hibernate 设计了 CriteriaSpecication 作为 Criteria 父接口下面提供了 Criteria和DetachedCriteria Criteria 和 DetachedCriteria 主要区别在于创建形式不样 Criteria 是在线所以它是由 Hibernate Session 进行创建；而 DetachedCriteria 是离线创建时无需SessionDetachedCriteria 提供了 2 个静态思路方法forClass(Class) 或 forEntityName(Name) 进行DetachedCriteria 例子创建 Spring 框架提供了getHibernateTemplate.findByCriteria(detachedCriteria) 思路方法可以很方便地根据DetachedCriteria 来返回查询结果 Criteria 和 DetachedCriteria 均可使用 Criterion 和 Projection 设置查询条件可以设置 FetchMode( 联合查询抓取模式 ) 设置排序方式对于 Criteria 还可以设置 FlushModel(冲刷 Session 方式)和 LockMode (数据库锁模式) 下面对 Criterion 和 Projection 进行详细介绍说明 Criterion 是 Criteria 查询条件Criteria 提供了 add(Criterion criterion) 思路方法来添加查询条件 Criterion 接口主要实现包括: Example 、 Junction 和 SimpleExpression 而 Junction 实际使用是它两个子类 conjunction 和 disjunction 分别是使用 AND 和 OR 操作符进行来联结查询条件集合 Criterion 例子可以通过 Restrictions 工具类来创建Restrictions 提供了大量静态思路方法如 eq (等于)、ge (大于等于)、 between 等来思路方法创建 Criterion 查询条件 (SimpleExpression 例子)除此的外Restrictions 还提供了思路方法来创建 conjunction 和 disjunction 例子通过往该例子 add(Criteria) 思路方法来增加查询条件形成个查询条件集合 至于 Example 创建有所区别 Example 本身提供了个静态思路方法 create(Object entity) 即根据个对象(实际使用中般是映射到数据库对象)来创建然后可以设置些过滤条件: Example exampleUser =Example.create(u) .ignoreCase // 忽略大小写 CriteriaType _or 的使用 生成的语句： select * from (select this_.ID as ID13_0_, this_.USER_NAME as USER2_13_0_, this_.USER_ID as USER3_13_0_, this_.ORG_NAME as ORG4_13_0_, this_.ORG_ID as ORG5_13_0_, this_.DEPT_NAME as DEPT6_13_0_, this_.DEPT_ID as DEPT7_13_0_, this_.USER_TITLE as USER8_13_0_, this_.APPRAISER_NAME as APPRAISER9_13_0_, this_.APPRAISER_ID as APPRAISER10_13_0_, this_.APPRAISER_TITLE as APPRAISER11_13_0_, this_.APPRAISER_MIND as APPRAISER12_13_0_, this_.REVIEW_DATE as REVIEW13_13_0_, this_.REVIEW_STATUS as REVIEW14_13_0_, this_.YEAR as YEAR13_0_, this_.BEGIN_DATE as BEGIN16_13_0_, this_.END_DATE as END17_13_0_, this_.CREATE_DATE as CREATE18_13_0_, this_.SIGN_DATE as SIGN19_13_0_, this_.SIGN_STATUS as SIGN20_13_0_, this_.POSITION_DESC as POSITION21_13_0_, this_.SCORE as SCORE13_0_, this_.CONTRACT_TYPE as CONTRACT23_13_0_, this_.DEL_FLAG as DEL24_13_0_ from PERF_PA_APRL_CONTRACT this_ where ((this_.ID in (select this0__.ID from PERF_PA_APRL_CONTRACT this0__ where this0__.USER_ID = ?) or this_.ID in (select this0__.ID from PERF_PA_APRL_CONTRACT this0__ where this0__.APPRAISER_ID = ?)) and this_.DEL_FLAG = ?)) where rownum <= ? Criteria的一些语句范例（方法） 一、Criteria的一些基本查询 Criteria有一个方法add(“限定条件”)，这个方法可以添加限定条件，好得到自己应该要的查询结果；例如：有两个实体类，student和teacher已经有一个Criteria的关于Student 类的实例Criteria crit = session.createCriteria(Student.class)； 1）在一个班级中要查询姓“王”的学生都有谁，就可以这样:List list = crit.add(Restrictions.like(“name”,”王%”)).list(); 2）查询年龄在17-20之间的学生：List list = crit.add(Restrictions.between(“age”,new Integer(17),new Integer(20))).list(); 3）查询没有手机号码的学生：List list = crit.add(Restrictions.isNull(tel)).list(); 4）查询90后的学生：List list = crit.add(Restrictions.ge(new Date(1990-01-01)).list(); 5）查询考试分数在前十名的学生（可用于分页查询）：List list = crit.addOrder(Order.desc(“grades”)).setFirstResult(0).setMaxResult(10).list(); 6）查询学生小明的个人信息：crit.add(Restriction.eq(“name”,”小明”)).list().iterator().next(); 7）查询小明的化学教师的信息：crit.add(Restricrions.eq(“name”,”小明”)).createCriteria(“teacher_id”).add(Restrictions.equ(“subject”,”化 学”)).list().iterator().next(); 8）以上都是先创建session根据session得到Criteria的实体对象（即在线查询），下面来看看离线查询，离线查询用的是DetachedCriteria类，DetachedCriteria类使你 在一个session范围之外创建一个查询，并且可以使用任意的Session来执行它。 下面写还按照上面的条件，写一个例子吧： DetachedCriteria query = DetachedCriteria.forClass(Student.class) .add( Property.forName("name").eq("小明") ); Session session = Configuration().configure().buildSessionFactory().openSession; Transaction txn = session.beginTransaction(); List results = query.getExecutableCriteria(session).setMaxResults(100).list(); https://www.doczj.com/doc/cf2589201.html,mit(); session.close(); 二、常用的一些基本的限定方法 Restrictions.eq --> equal,等于. Restrictions.allEq -->参数为Map对象,使用key/value进行多个等于的比对,相当于多个Restrictions.eq的效果 Restrictions.gt --> great-than >大于 Restrictions.ge --> great-equal >= 大于等于 Restrictions.lt --> less-than, <小于 Restrictions.le --> less-equal <= 小于等于 Restrictions.between -->对应SQL的between子句 Restrictions.like -->对应SQL的LIKE子句 Restrictions.in -->对应SQL的in子句 Restrictions.and --> and 关系Hibernate中Criteria的完整用法
