我无法将此代码添加到GROUP BY？

我不明白错误!!

ANSI SQL标准的一个非常烦人的功能是，任何不是聚合的列都需要包含在GROUP BY子句中。这是一个经典的愚蠢重复，当它显而易见时（我相信MySQL允许我们忽略这部分标准）。
所以，我担心它意味着什么，你需要在GROUP BY子句中包含CASE()子句。
我认为问题在于您在查询中的两个级别引用SUM()：在最顶层，SUM(B.RISK)，但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
要想做到这一点非常棘手。
我认为解决此问题的最简单方法是从嵌套内联查询构建查询。我已经用三个级别重写了你的查询。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。最外层的查询适用于舍入和其他事物;这应该根据您现有的查询返回结果。

显然，这可能无法编译 - 我没有检查您的数据库架构。逻辑也可能是错误的;我不得不对你的业务逻辑做出假设。但是，我认为这更容易理解，并且更容易调试。
答案 1 :(得分：2)
, 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 )
这不是聚合函数。只有SUM部分在那里。使用Analytic functions。
答案 2 :(得分：1)
首先，您可能希望下次发布一个完整的示例 - 在尝试运行查询时，我得到至少4个未定义函数和2个不存在表的错误（S_TEKLIF，GECIKME_CV，ipotek，risk_cv，m_v， mv_ex - 之后我放弃了）。
第二：尝试将其分为两个查询，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

您的case引用了一个select语句 - 并且您不能在group by子句中使用select语句。
