Hibernate学习之HQL查询

原文地址：https://github.com/mageSFC/myblog/blob/master/Hibernate%E5%AD%A6%E4%B9%A0%E4%B9%8BHQL%E6%9F%A5%E8%AF%A2.md

Hibernate学习之HQL查询
马哥私房菜博客地址：https://github.com/mageSFC/myblog

HQL(hibernate query language)是面向对象的查询语言，他和sql查询语言有些相似。
在hibernate提供的各种检索方式中，hql是使用最广泛的一种检索方式，它具有如下功能：
1.在查询语句中设定各种查询条件
2.支持投影查询，即仅检索出对象的部分属性
3.支持分页查询
4.支持链接查询
5.支持分组查询，允许使用having和group by关键字
6.提供内置聚集函数，如sum(),min(),max()
7.支持子查询
8.支持动态绑定参数
9.能够调用用户定义的sql函数或者标准的sql函数

下面的例子我们采用了oracle数据库

oracle数据库安装在了windows上面。

oracle远程访问开启：

解决方法：

查看端口状态：CMD -> netstat -a -n
显示的结果是：1521端口对应的本地地址栏为：127.0.0.0:1521,
此时，修改Oracle安装目录下dbhome_1\NETWORK\ADMIN\listener.ora文件（或是PLSQL下的对应文件instantclient_11_2\listener.ora）的HOST值，改为0.0.0.0。
重启Oracle监听服务；
再次通过netstat查看端口信息,显示：1521端口对应的本地地址栏为：0.0.0.0:1521
这时通过127.0.0.1或loaclhost或主机名或本机ip都可telnet通过。

在Windows系统下完成Oracle安装后，在其防火墙设置中开放1521端口（Oracle默认的侦听端口）。若客户端仍然无法访问，则需要作进一步的设置，即在注册表“HKEY_LOCAL_MACHINE” - “Software” - “ORACLE” - “HOME”下添加一个注册表项“USE_SHARED_SOCKED”，并将其值设为TRUE，然后重启Oracle服务及Listener服务。

总结：
Oracle Telnet 1521失败，要检查以下几点：
1、防火墙是否开启，若开启，是否有对1521端口开启；
2、listener.ora文件的HOST值。

注：10.2以上，USE_SHARDED_SOCKET就已经是默认值为TRUE了，无需再修改。

最后通过nmap命令可以看到1521端口是open的状态表明可以了

$ nmap 10.0.63.42

添加oracle的jdbc驱动文件

把从官网下载的oracle的jdbc驱动jar包放到家目录下面执行下面命令：
$ mvn install:install-file -Dfile=ojdbc8.jar -DgroupId=com.oracle -DartifactId=ojdbc8 -Dversion=12 -Dpackaging=jar

数据库表的导入？
使用sql developer，

执行 @D:/del_data.sql
执行 @D:/hr_cre.sql
执行 @D:/hr_popul.sql
这样就把sql文件导入到数据库里面了。

我们执行我们的项目，让其自动的再创建2长表，一个是hb_department, 另一个是hb_employee, 这个是在hbm配置文件里面定义的表格名的。

接下来我们把刚刚导入的sql文件中有一个departments表的数据导入到这个hb_department表,

sql> INSERT  INTO  hb_department SELECT DEPARTMENT_ID,DEPARTMENT_NAME from DEPARTMENTS
[2018-01-15 16:32:52] 27 rows affected in 37ms

然后通用的操作包employees表格中的数据导入到hb_employee表，

sql> INSERT  INTO  HB_EMPLOYEE SELECT  EMPLOYEE_ID,LAST_NAME,SALARY,EMAIL,DEPARTMENT_ID FROM EMPLOYEES
[2018-01-15 16:34:36] 107 rows affected in 10ms

分页查询
setFirstResult(int firstResult)设定从哪一个对象开始检索，参数 firstResult 表示这个对象在查询结果中的索引位置，
索引位置的起始值是0，默认情况下query从查询结果中的第一个对象开始检索。

setMaxResult(int maxResult)设定一次最多检索出的对象数目，在默认情况下，query和criteria接口检索出查询结果中所有的对象

从第三页开始，每页显示5条记录。这里结果正好是从110id开始的。

命名查询
一个和class并列的一个标签 query标签
可以把hql语句配置到xml配置文件中

马哥私房菜博客地址：https://github.com/mageSFC/myblog


"com.mamh.hibernate.hql.entities">

    <class name="Employee" table="hb_employee">
        <id name="id" type="java.lang.Integer">
            name="id"/>
            class="native"/>
        id>

        <property name="name" type="java.lang.String">
            name="name"/>
        property>


        <property name="salary" type="float">

    name="salary">
        where e.salary > :minSalary and e.salary < :maxSalary
            ]
        ]
        >

    @Test
    public void testHQL3() {
        Query query = session.getNamedQuery("salary");

        query.setFloat("minSalary", 5000);
        query.setFloat("maxSalary", 10000);

        List list = query.list();
        System.out.println(list.size());
    }

投影查询
查询结果仅包含实体的部分属性
“`
String hql = “” +
“select new Employee (e.id, e.name,e.salary,e.email) ” +
“from Employee e ” +
“where e.dept= :dept”;

关键就是这里的hql语句，用的了    Employee 的带参数的一个构造方法

@Test
public void testHQL4() {
    String hql = "select e.email,e.salary from Employee e where e.dept= :dept";
    Query query = session.createQuery(hql);

    Department dept = new Department();
    dept.setId(80);
    List
