sql - Not a Group By expression Error

Question

I have a SQL like this;

SELECT B.MUS_K_ISIM AS CUSTOMER_NAME, B.HESAP_NO AS CUSTOMER_NO,
    SUM(B.RISK) AS TOTAL_RISK, 
    (CASE WHEN B.DOVIZ_KOD = 21 THEN 'EUR' WHEN B.DOVIZ_KOD = 2 THEN 'USD' WHEN B.DOVIZ_KOD = 1 THEN 'TL' END) AS CCY,
    ROUND(RISK_CV(:TAR,B.HESAP_NO,B.DOVIZ_KOD),2) AS TOTAL_RISK_EUR,
    ROUND(SUM(MV_EX(B.TEKLIF_NO1,B.TEKLIF_NO2,:TAR)),2) AS RESALE_VALUE_OLD,
    ROUND(SUM(M_V(B.TEKLIF_NO1,B.TEKLIF_NO2,:TAR)),2) AS RESALE_VALUE_NEW,
    NVL(IPOTEK(B.HESAP_NO),0) AS SECURITIES,
    NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 0, 30, B.DOVIZ_KOD),2),0) AS BUCKET1,
    NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 30, 60, B.DOVIZ_KOD),2),0) AS BUCKET2,
    NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 60, 90, B.DOVIZ_KOD),2),0) AS BUCKET3,
    NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD),2),0) AS BUCKET4,
    (CASE WHEN GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD) > 0 THEN 100 WHEN B.HESAP_NO IN (SELECT HESAP_NO FROM S_TAKIP_MUSTERI) THEN 100 ELSE 0 END) AS PROV,
    (CASE WHEN B.HESAP_NO IN (SELECT HESAP_NO FROM S_TAKIP_MUSTERI) THEN 'E' ELSE 'H' END) AS CAT5,
    ROUND(RISK_CV(:TAR,B.HESAP_NO,B.DOVIZ_KOD)-SUM(M_V(B.TEKLIF_NO1,B.TEKLIF_NO2,:TAR))-NVL(IPOTEK(B.HESAP_NO),0),2) AS NET_PROV,
    (CASE WHEN (RISK_CV(:TAR,B.HESAP_NO,B.DOVIZ_KOD)-SUM(M_V(B.TEKLIF_NO1,B.TEKLIF_NO2,:TAR))-NVL(IPOTEK(B.HESAP_NO),0))<0 OR 
    NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD),2),0) <= 0 THEN 0 
    ELSE ROUND((RISK_CV(:TAR,B.HESAP_NO,B.DOVIZ_KOD)-SUM(M_V(B.TEKLIF_NO1,B.TEKLIF_NO2,:TAR))-NVL(IPOTEK(B.HESAP_NO),0)),2) END) AS CORR_PROV
    FROM S_TEKLIF B
    WHERE NVL(B.RISK,0) > 0 
    --AND (GECIKME_CV(:TAR,B.HESAP_NO, 60, 90, B.DOVIZ_KOD) > 0 OR GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD) > 0) 
    GROUP BY B.MUS_K_ISIM, B.HESAP_NO, (CASE WHEN B.DOVIZ_KOD = 21 THEN 'EUR' WHEN B.DOVIZ_KOD = 2 THEN 'USD' WHEN B.DOVIZ_KOD = 1 THEN 'TL' END), ROUND(RISK_CV(:TAR,B.HESAP_NO,B.DOVIZ_KOD),2), NVL(IPOTEK(B.HESAP_NO),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 0, 30, B.DOVIZ_KOD),2),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 30, 60, B.DOVIZ_KOD),2),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 60, 90, B.DOVIZ_KOD),2),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD),2),0), (CASE WHEN GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD) > 0 THEN 100 WHEN B.HESAP_NO IN (SELECT HESAP_NO FROM S_TAKIP_MUSTERI) THEN 100 ELSE 0 END), (CASE WHEN B.HESAP_NO IN (SELECT HESAP_NO FROM S_TAKIP_MUSTERI) THEN 'E' ELSE 'H' END)
    ORDER BY B.MUS_K_ISIM

But i getting this error.

ORA-00979: not a GROUP BY expression
00979. 00000 -  "not a GROUP BY expression"
*Cause:    
*Action:

I can't put this code to GROUP BY?

(CASE WHEN GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD) > 0 THEN 100 WHEN B.HESAP_NO IN (SELECT HESAP_NO FROM S_TAKIP_MUSTERI) THEN 100 ELSE 0 END)

I don't understand the error!!

Answer 1

 , ROUND ( RISK_CV ( :TAR , B.HESAP_NO , B.DOVIZ_KOD )
         - SUM ( M_V ( B.TEKLIF_NO1 , B.TEKLIF_NO2 , :TAR ) )
  - NVL ( IPOTEK ( B.HESAP_NO ) , 0 ) , 2 )         

这不是一个聚合函数。只有 SUM 部分在那里。使用分析函数。

Answer 2

ANSI SQL 标准的一个非常烦人的特性是，任何不是聚合的列都需要包含在 GROUP BY 子句中。这是一个典型的愚蠢重复，当它很明显时（我相信 MySQL 允许我们忽略标准的这一部分）。

所以，恐怕这意味着，您需要CASE()在 GROUP BY 子句中包含该子句。

我认为问题在于您SUM()在查询中引用了两个级别：既在最顶层，SUM(B.RISK)也在提供分组值的计算中：

( CASE WHEN ( RISK_CV ( :TAR , B.HESAP_NO , B.DOVIZ_KOD )
                   - SUM ( M_V ( B.TEKLIF_NO1 , B.TEKLIF_NO2 , :TAR ) )
                   - NVL ( IPOTEK ( B.HESAP_NO ) , 0 ) ) < 0

这很难做到正确。

我认为解决此问题的最简单方法是从嵌套的内联查询构建查询。我已经用三个级别重新编写了您的查询。最里面的查询 - IQ- 选择数据，包括没有任何聚合的函数。中间查询 - SQ- 计算总和。最外层的查询应用舍入和其他东西；这应该根据您现有的查询返回结果。

显然，这可能无法编译 - 我没有要检查您的数据库模式。逻辑也可能是错误的；我不得不对您的业务逻辑做出假设。但是，我确实认为这更容易理解并且更容易调试。

Answer 3

首先，您下次可能想发布一个完整的示例 - 在尝试运行查询时，我收到至少 4 个未定义函数和 2 个不存在的表（S_TEKLIF、GECIKME_CV、ipotek、risk_cv、m_v、mv_ex - I后来放弃了）。

第二：尝试将其拆分为两个查询，例如

select mus_k_isim, hesap_no, my_key, ... from 
(select mus_k_isim, b.hesap_no, 
  (CASE WHEN B.DOVIZ_KOD = 21 THEN 'EUR' WHEN B.DOVIZ_KOD = 2 THEN 'USD' WHEN B.DOVIZ_KOD = 1 THEN 'TL' END), ROUND(RISK_CV(:TAR,B.HESAP_NO,B.DOVIZ_KOD),2), NVL(IPOTEK(B.HESAP_NO),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 0, 30, B.DOVIZ_KOD),2),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 30, 60, B.DOVIZ_KOD),2),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 60, 90, B.DOVIZ_KOD),2),0), NVL(ROUND(GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD),2),0), (CASE WHEN GECIKME_CV(:TAR,B.HESAP_NO, 90, 9999, B.DOVIZ_KOD) > 0 THEN 100 WHEN B.HESAP_NO IN (SELECT HESAP_NO FROM S_TAKIP_MUSTERI) THEN 100 ELSE 0 END), (CASE WHEN B.HESAP_NO IN (SELECT HESAP_NO FROM S_TAKIP_MUSTERI) THEN 'E' ELSE 'H' END) my_key
from ...
) group by mus_k_isim, hesap_no, my_key

Answer 4

您case引用了一个 select 语句 - 您不能在 group by 子句中有一个 select 语句。
