关于hql语句的问题

[qq_35842815]

代码如下

public boolean doRemove(Integer id) throws Exception {

		try {

			Statement statement = getHibernateTemplate().getSessionFactory().openStatelessSession().connection()
					.createStatement();
			String hql = " delete from messageelementlink where messageid='" + id + "' and pervMessageId='" + id + "'";
			statement.execute(hql);
			hql = " delete from Messageelement where messageid='" + id + "' ";
			statement.execute(hql);
			hql = " delete from messagegroup where messageid='" + id + "' ";
			statement.execute(hql);
			hql = " delete from Message where id='" + id + "' ";
			statement.execute(hql);

		} catch (Exception e) {
			System.out.print(e.getMessage());
		}

		// super.getHibernateTemplate().delete(findById(id));
		return true;
	}

hql = " delete from Messageelement where messageid='" + id + "' ";
hql = " delete from Message where id='" + id + "' ";
这两条语句from后面跟的是类名

hql = " delete from messagegroup where messageid='" + id + "' ";
这条from后面跟的应该是表名 ，
不是说hql的from后面跟类名么 到底是怎么回事？

应该是类名吧，虽然也可以写成sql，但是应该不会有混用的
