學說2 DQL子查詢

Question

我想在FROM塊中通過Doctrine 2.3 DQL使用子查詢。

每次IM以下錯誤

[Semantical Error] line 0, col 839 near '(SELECT ': Error: Class '(' is not defined. 

這是我目前DQL代碼

$query = $this->getEntityManager()->createQuery(' 
SELECT 
     taS2.netDueDate, 
     SUM(taS2.amountInThousands)      AS SumAmountInThousands, 
     SUM(taS2.netDAO1)          AS SumnetDAO1, 
     SUM(taS2.netDAO2)            AS SumnetDAO2, 
     SUM(taS2.netDAO3)           AS SumnetDAO3, 
     SUM(taS2.netDAO4)            AS SumnetDAO4, 
     SUM(taS2.netDueDate * taS2.amountInThousands) AS SumNetDueDateInThousands, 
     SUM(taS2.critical) 
FROM 
    (SELECT 
     ta.id, 
     ta.documentDate, 
     SUBSTRING(CONCAT(ta.netDueDate, \'\'), 9, 2) AS netDueDate, 
     ta.discountRate, 
     ta.amountInThousands, 
     ta.netDAO1, 
     ta.netDAO2, 
     ta.netDAO3, 
     ta.netDAO4, 
     ta.netDueDate, 
     1 AS counter, 
     CASE 
      WHEN (ta.clearingDate > ta.netDueDate) AND 
        SUBSTRING(CONCAT(ta.clearingDate, \'\'), 6, 2) <> SUBSTRING(CONCAT(ta.netDueDate, \'\'), 6, 2) 
      THEN ta.amountInThousands ELSE 0 
     END AS critical 
    FROM 
     AcmeBundle:Transaction ta 
    WHERE 
     ta.discountRate = 0) taS2 

GROUP BY taS2.netDueDate 
ORDER BY SUM(taS2.amountInThousands) DESC; 
); 

大家有一個想法，我怎麼做到這一點正常運行這一點，得到些什麼？

您的查詢看起來更像普通SQL，並具有一些DQL的功能。您可以執行SQL查詢與$this->getEntityManager()->createNativeQuery();
