轉換從SQL到HQL失敗

Question

試圖從這裏這個SQL去：

SELECT DISTINCT iss.ID 
FROM   Issue AS iss 
INNER JOIN  Message ON Message.IssueID = iss.ID 
INNER JOIN  Clinician ON Clinician.UserID = Message.FromUserID 
INNER JOIN  OrgUnit ON OrgUnit.ID = Clinician.OrgUnitID 
WHERE   OrgUnit.ID = [id-number] 

要在這裏HQL：

select distinct iss.id from iss 
inner join iss.messages as msg 
inner join msg.Sender.OrgUnit as org 
where org = :orgUnit 

但我不斷收到 「多標識符無法綁定」

映射：
- 問題-

<bag name="messages" access="field" inverse="false" lazy="true" cascade="none"> 
    <key column="IssueID" /> 
    <one-to-many class="Message" /> 
</bag> 

- 臨牀醫生 -

<joined-subclass name="Clinician" table="Clinician" lazy="true"> 
    <key column="UserID" /> 
    <many-to-one name="OrgUnit" column="OrgUnitID" /> 
</joined-subclass> 

Answer 1

剛纔發現對這個問題最簡單的回答是避免它。它在SQL中工作，所以爲什麼不在SQL中執行。
