次のようなビューがあります-問題なくコンパイルされますが、そこから選択しようとすると、ORA-00979: not a GROUP BY expression エラーが発生します。ビューからサブクエリ (列 4) を削除すると、すべて正常に動作します。どんなアイデアでも大歓迎です！ありがとう！！

group by を使用する必要がある場合 (集計関数を追加する場合はこれが当てはまりますが、クエリが現在作成されているわけではありません)、サブクエリgroup byも同様に含める必要があります。SELECTメインクエリの外側に追加GROUP BYし、そのレベルで適用することで、これを最も簡単に追加できます。

select lab_group, lab, bench, rfr
from 
(
   select
      l.LAB_GROUP as lab_group,
      l.NAME as LAB,
      b.NAME as BENCH,
      (select .....) as RFR
   from LABORATORY l
      inner join LABORATORY_ENTRY le on le.NAME = l.NAME 
      inner join X_BENCH b on b.NAME = le.X_BENCH
      left join (SAMPLE s inner join TEST t on ...) on 
          t.ANALYSIS = le.ANALYSIS and 
          s.LAB_GROUP = l.LAB_GROUP
      left join V_LOC_DEPT_FAC ldf on ldf.LOCATION_NUMBER = s.STORAGE_LOC_NO 
) x
group by lab_group, lab, bench, rfr
