意外的AST節點左外部連接

我被困在一個查詢，我試圖從SQL轉換到JPQL。首先是兩個SQL查詢運行良好，最後是我的失敗查詢以及錯誤：意外的AST節點左外部連接

//SUCCEEDS-----! 
//select * from defermentaccount LEFT OUTER JOIN division ON defermentaccount.deferment_ID=division.divisionID; 
//select * from defermentaccount d LEFT OUTER JOIN division v ON d.deferment_ID=v.divisionID; 
//FAILS--------!  
Query q1 = em.createQuery("SELECT defm FROM DefermentAccount defm LEFT JOIN defm.division division ON division.divisionID=:defm.defermentID");

任何幫助非常感謝！

STACK：

感謝您的幫助，但我認爲這就是我已經... ...？ Query q1 = em.createQuery（「SELECT defm FROM DefermentAccount defm LEFT JOIN defm.division division ON division.divisionID =：defm.defermentID」）; ------ org.hibernate.hql.internal.ast.QuerySyntaxException：unexpected AST節點：在第1行附近， – 2014-11-21 16:31:26

「defm」實際上是列名嗎？你已經使它成爲一個表別名。 – 2014-11-21 16:32:39

沒有定義列，但也不是延遲帳戶列。 DDL - （ deferment_ID BIGINT PRIMARY KEY NOT NULL AUTO_INCREMENT， deferment_Account_End_Date DATETIME， deferment_Account_Max_Balance DECIMAL（12,2）， deferment_Account_Notes VARCHAR（255）， deferment_Account_Number VARCHAR（255）， deferment_Account_Start_Date DATETIME， division_Deferment_Join_Column BIGINT， FOREIGN KEY（division_Deferment_Join_Column）REFERENCES部門（divisionID））; CREATE INDEX FK_lc3jh0hjn8mbrhqqwjbes7mle ON defermentaccount（division_Deferment_Join_Column）; – 2014-11-21 16:35:05

兩件事情：

defm並不似乎是一個列，以便將其更改爲*或你想要的列。
也= =在這裏不需要，因爲你正在做一個左連接語法。我相信：=或=：是用於連接的舊ANSI樣式SQL。

。

SELECT * 
FROM DefermentAccount defm 
LEFT JOIN defm.division division 
ON division.divisionID=defm.defermentID

嗨謝謝，但我不是在SQL之後 - - 我需要JPQL語法。謝謝 - 我最初給出的SQL作品。 – 2014-11-21 16:41:26

我覺得這個帖子可能會有答案：http://stackoverflow.com/questions/4992834/left-join-on-in-jpql - 但我不能讓查詢編譯SQL使用WHERE：它是推斷JPQL中沒有'ON' – 2014-11-21 16:52:56

我並不需要開啓，或者 - 它只有

作品「SELECT defm，divis FROM DefermentAccount defm LEFT OUTER JOIN defm.division divis」
