Hibernate中使用SQLQuery

Hibernate中使用SQLQuery的查询：

BaseHibernateDAO dao = new BaseHibernateDAO();
//查询语句
String strSql = " select * from hrrole h where h.code like ? and h.id <> ?";
//设置查询对象
SQLQuery query = dao.getSession().createSQLQuery(strSql);
//设置查询参数
query.setString(0,(String)this.getCode().getText());
//设置查询参数
query.setString(1,this.getTextField1().getText().toString());
//添加到一个类中
query.addEntity(HrRole.class);
//结果数据
ArrayList<HrRole> idlist = (ArrayList<HrRole>) query.list();
//判断是否有值
if(idlist.size() != 0){
//错误信息
this.label2.setText("代码已存在");
}

Hibernate中使用SQLQuery的更新：

public void updateR(String Code,String NewCode){
BaseHibernateDAO dao = new BaseHibernateDAO();
try{
Transaction tx = dao.getSession().beginTransaction();
String sql1 = "update roleandgrant set rolecode = '" + Code + "'" + " where rolecode ='" + NewCode + "'";
String sql2 = "update emprole set rolecode = '" + Code + "'" + " where rolecode ='" + NewCode + "'";
SQLQuery query1 = dao.getSession().createSQLQuery(sql1);
SQLQuery query2 = dao.getSession().createSQLQuery(sql2);
query1.addEntity(RoleAndGrant.class);
query2.addEntity(EmpVsRole.class);
query2.executeUpdate();
query1.executeUpdate();
tx.commit();
dao.closeSession();
}catch(Exception ex){
System.out.println(ex);
dao.closeSession();
}
}

Hibernate中使用SQLQuery的删除：

public void DeleteR(String Code){
BaseHibernateDAO dao = new BaseHibernateDAO();
try{
Transaction tx = dao.getSession().beginTransaction();
String sql1 = "delete from roleandgrant where rolecode ='" + Code + "'";
String sql2 = "delete from emprole where rolecode ='" + Code + "'";
SQLQuery query1 = dao.getSession().createSQLQuery(sql1);
SQLQuery query2 = dao.getSession().createSQLQuery(sql2);
query1.addEntity(RoleAndGrant.class);
query2.addEntity(EmpVsRole.class);
query2.executeUpdate();
query1.executeUpdate();
tx.commit();
dao.closeSession();
}catch(Exception ex){
System.out.println(ex);
dao.closeSession();
}
}
