问题上HQL查询

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) 

的问题是，该结果集，这还不包括由在过滤器上的所有条目：a.genericTable is null

有谁知道这是为什么？

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))
