越来越org.hibernate.hql.internal.ast.QuerySyntaxException错误

Question

如上所述，我得到上述异常。

你能帮忙吗？感谢

我已经看了各种指南/教程和他们真的不告诉你什么是运行这样的例子所需要的映射。或者我见过的例子并没有涉及检索数据的任何事情。这主要是关于插入/更新和删除。

从JBoss DOC（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 

此示例是我的HQL：

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

这是我的XML映射

Answer 1

如果你正在试图做的右连接，取出（ +）并尝试

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