HQL查詢與where子句

Question

我想查詢休眠對於給定的情景：

我的數據模型

類通訊：

變量：主體，sentTo，創造者。

現在讓我們說在usera和userb之間交換了一些筆記。我想通過hibernate查詢找到所有這些筆記。我寫下了我的查詢字符串。

select note from Communication n where n.subject=:subject and ((n.sentTo=:sentto and n.creator=:creator) or (n.sentTo:creator and n.creator=:sentto)) 

但hibernate無法解析此查詢。請建議做什麼？

Answer 1

嘗試使用：

select note from Communication n where n.subject=:subject and ((n.sentTo=:sentto and n.creator=:creator) or (n.sentTo:creator and n.creator=:sentto)) 

別名Communication失蹤，你想通過它的別名'n'訪問它（這是沒有定義）

感謝

Answer 2

我不知道是否有錯誤，但你的別名n不似乎是在查詢中定義。

你能給我們堆棧跟蹤嗎？

Answer 3

休眠正在下降在這裏：

(n.sentTo:creator and n.creator=:sentto) 
---------^ 

我懷疑這應該是

(n.sentTo = :creator and n.creator=:sentto) 
---------^^^
