Hibernate HQL join for joined table

Question

我正在尝试创建 HQL 查询，这里是：

     query = "SELECT test From Result result " +
                    "JOIN result.test test JOIN result.user user " +
                    "WHERE test.id = :testId AND user.id = :userId " +
                    "AND result.permission.id = :permissionId"),

现在我想添加额外的问题（多对一的测试）和答案（多对一的问题）。如果我尝试这样的事情：

     query = "SELECT test From Result result " +
                    "JOIN result.test test JOIN result.user user JOIN test.questions as question" +
                    "WHERE test.id = :testId AND user.id = :userId " +
                    "AND result.permission.id = :permissionId")

我得到一个例外。

这里有错误（需要space）

"JOIN result.test test JOIN result.user user JOIN test.questions as question"

我想知道你为什么需要加入问题...你不会在什么地方使用它。
