Question

如上所述，我得到了上述例外情况。

你能帮帮忙吗？感谢

我查看了各种指南/教程，他们并没有真正告诉你运行这些示例所需的映射是什么。或者我见过的例子并没有涉及检索数据的任何内容。它主要是关于插入/更新和删除。

来自jboss doc的示例（http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html/ch16.html）

select foo
from Foo foo, Bar bar
where foo.startDate = bar.date

这是我的HQL：

sessionFactory.getCurrentSession().createQuery("from Staff staff, Url url where (staff.id = url.id (+))");

这是我的映射XML

Answer 1

如果您尝试进行正确的加入，请删除（+）并尝试

sessionFactory.getCurrentSession().createQuery("from Staff staff right join Url url where (staff.id = url.id)");

获取org.hibernate.hql.internal.ast.QuerySyntaxException错误
