問題上HQL查詢

Question

我有以下HQL查詢：

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

的問題是，該結果集，這還不包括由在過濾器上的所有條目：a.genericTable is null

有誰知道這是爲什麼？

謝謝！

嘗試左連接：

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