Hibernate(十)HQL查询二

一、数据库的emp名和dept表

建立持久化类和配置文件，可以用MyEclipse直接生成

持久化类

package entity;

import java.util.Date;

public class Emp implements java.io.Serializable {

    // Fields

    private Short empno;
    private Dept dept;
    private String ename;
    private String job;
    private Short mgr;
    private Date hiredate;
    private Double sal;
    private Double comm;

    // Constructors

    /** default constructor */
    public Emp() {
    }

    /** minimal constructor */
    public Emp(Short empno) {
        this.empno = empno;
    }

    /** full constructor */
    public Emp(Short empno, Dept dept, String ename, String job, Short mgr,
            Date hiredate, Double sal, Double comm) {
        this.empno = empno;
        this.dept = dept;
        this.ename = ename;
        this.job = job;
        this.mgr = mgr;
        this.hiredate = hiredate;
        this.sal = sal;
        this.comm = comm;
    }

    // Property accessors

    public Short getEmpno() {
        return this.empno;
    }

    public void setEmpno(Short empno) {
        this.empno = empno;
    }

    public Dept getDept() {
        return this.dept;
    }

    public void setDept(Dept dept) {
        this.dept = dept;
    }

    public String getEname() {
        return this.ename;
    }

    public void setEname(String ename) {
        this.ename = ename;
    }

    public String getJob() {
        return this.job;
    }

    public void setJob(String job) {
        this.job = job;
    }

    public Short getMgr() {
        return this.mgr;
    }

    public void setMgr(Short mgr) {
        this.mgr = mgr;
    }

    public Date getHiredate() {
        return this.hiredate;
    }

    public void setHiredate(Date hiredate) {
        this.hiredate = hiredate;
    }

    public Double getSal() {
        return this.sal;
    }

    public void setSal(Double sal) {
        this.sal = sal;
    }

    public Double getComm() {
        return this.comm;
    }

    public void setComm(Double comm) {
        this.comm = comm;
    }

}
