Hql查询问题

Question

我有以下hql查询：

from Admin a where a.genericTable is null or (a.genericTable.allowInsertion = true or a.genericTable.allowInsertion is null)

问题是结果集排除了过滤器中包含的所有条目：a.genericTable is null

有谁知道为什么？

谢谢！

尝试左连接：

from Admin as a left join a.genericTable as g
where (g is null or (g.allowInsertion = true or g.allowInsertion is null))
