グループBy Statementエラー

Question

私は以下のコードを持っていますが、私は報告の理由からCMMSシステムデータベースに問い合わせています。 Group byを削除すると、実行されますが、Whereステートメントによって返されたすべての実行がカウントされます。私はそれがGroup Byステートメントを使用していないためだと推測しています。すべてのボディは素晴らしいことだ正しい方向に私を指すことができる場合

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

：私は私にそれを追加すると、次のエラーを取得します。
