私はSQLこのようなものを持っています。

しかし、私はこのエラーを受け取ります。

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

私はこのコードを置くことができませんGROUP BYか？

(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)

エラーがわかりません!!

集計ではない列をGROUPBY句に含める必要があることは、ANSISQL規格の非常に厄介な機能です。これは、明らかな場合、愚かな複製の古典的な部分です（MySQLでは標準のこの部分を無視できると思います）。

ですから、それが何を意味するのか、私は恐れていますCASE()。GROUPBY句に句を含める必要があります。

SUM()問題は、クエリの2つのレベルで参照していることだと思います。両方とも最上位レベルSUM(B.RISK)だけでなく、グループ化値を提供する計算でも次のようになります。

( 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

これを正しく行うにはかなり注意が必要です。

これを解決する最も簡単な方法は、ネストされたインラインクエリからクエリを作成することだと思います。クエリを3つのレベルで書き直しました。最も内側のクエリ---IQ集計なしの関数を含むデータを選択します。真ん中のクエリSQ---合計を計算します。最も外側のクエリは、丸めなどを適用します。これにより、既存のクエリに従って結果が返されます。

明らかに、これはコンパイルされない可能性があります-私はあなたのデータベーススキーマをチェックする必要がありません。また、ロジックが間違っている可能性があります。私はあなたのビジネスロジックについて仮定を立てなければなりませんでした。ただし、これは理解しやすく、デバッグも容易になると思います。

これは集計関数ではありません。SUM部分のみがあります。分析関数を使用します。

まず、次回は完全な例を投稿することをお勧めします-クエリを実行しようとすると、少なくとも4つの未定義関数と2つの存在しないテーブル（S_TEKLIF、GECIKME_CV、ipotek、risk_cv、m_v、mv_ex-Iその後あきらめた）。

2番目：これを2つのクエリに分割してみてください。

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

selectステートメントを参照します-groupbycase句にselectステートメントを含めることはできません。
