Hibernate学习之HQL查询
马哥私房菜

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

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,

1
2
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，

1
2
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

String hql = "" +

        "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

HQL(迫切)左外链接

马哥私房菜

迫切左外链接：使用left join fetch 关键字
list()方法返回的集合中存放实体对象引用，每个department对象关联的employee集合都被
初始化，存放所有关联的employee的实体对象
查询结果中可能会有重复元素，可以通过hashset来过滤重复元素

马哥私房菜

左外链接：使用left join 关键字
list()方法返回的集合中存放的是对象数组类型
根据配置文件来决定employee结合的检索策略
如果希望list()方法返回的集合中仅包含department对象，可以在hql查询语句中使用select关键字

左外链接：使用left join 关键字
list()方法返回的集合中存放的是对象数组类型
根据配置文件来决定employee结合的检索策略
如果希望list()方法返回的集合中仅包含department对象，
可以在hql查询语句中使用select关键字

HQL (迫切)内连接

迫切内连接： 不返回左表不满足条件的记录
inner join fetch关键字表示迫切内连接，也可以省略inner关键字
list()方法返回的集合中存放department对象的引用，每个department对象的employee集合都被初始化
存放所有关联的employee对象

内连接：
inner join关键字表示内连接，也可以省略inner关键字
