Question

1，hibernate中用hql怎么执行delete的sql语句

Answer 1

你可以使用一楼的方式

如果使稿散用hql方式，参考如下：掘氏

public void testDml(){
Session session = null;
Transaction tx = null;
try {
session = HibernateUtils.getSession();
tx = session.getTransaction();
session.beginTransaction();
Query query = session.createQuery("delete Student s where s.id=?"键散氏);
query.setInteger(0, 1);
query.executeUpdate();
tx.commit();
} catch (HibernateException e) {
tx.rollback();
e.printStackTrace();
}finally{
HibernateUtils.closeSession(session);
}
}

Answer 2

Session s = this.getHibernateTemplate().getSessionFactory().openSession();//获取session

Transaction tx = s.beginTransaction(); //打开事正衫行务（针对读数据库）

String hql="delete .... where a=?...";//准备hql

s.createQuery(hql).setString("a",值).executeUpdate();//更塌岁新

tx.commit();//提举哗交事务

s.close(); //关闭session

Answer 3

getHibernateTemplate().delete(Entity)
