複数のサブクエリを含む大きな SELECT クエリを作成しています。各サブクエリは、そのうちの 1 つ (「トン/メートル」) を除いて正常に機能します。他のものと同じリンクと値を使用しましたが、別のデータベースの別のテーブルを使用しています。しかし、構文は私には正しいように見えます。問題のあるサブセレクトを引き出して単独で実行すると、機能します。

これは、行の 1 つを正常に返す TEST 副選択 (ハードコーディングされたパラメーターを使用) です ...

  SELECT SUM((OreNo*CONVERT(decimal(10,2),ISNULL(round((Code1),2),0))) + (WasteNo*CONVERT(decimal(10,2),ISNULL(round((Code2),2),0))) + (WFG*CONVERT(decimal(10,2),ISNULL(round((Code3),2),0))))

...そして、これはそれが返す行です...

Tones/Metres の CASE ステートメントに ELSE ステートメントがありません。ELSEステートメントを追加してみて、else 値が返されるかどうかを確認すると、条件が正しく機能していないことがわかります。

(これは OperationalAssetDetail.Name != 'LD%' になります)

ケース条件が機能していないことがわかっている場合は、これをケースとして試して、「Wenis」が返されるかどうかを確認してください。

CASE OperationalAssetDetail.Name WHEN 'LD%' THEN ( SELECT SUM((OreNo*CONVERT(decimal(10,2),ISNULL(round((Code1),2),0))) + (WasteNo*CONVERT(decimal(10,2),ISNULL(round((Code2),2),0))) + (WFG*CONVERT(decimal(10,2),ISNULL(round((Code3),2),0)))) FROM BETA..Bogging, BETA..Equipment, OperationalAssetDetail WHERE EquipmentName = @myAsset and OperationalAssetDetail.Name = EquipmentNameMainpac and BETA..Bogging.EquipmentID = BETA..Equipment.EquipmentID and months = RTRIM(CAST(DATEPART(year, Date) AS CHAR)) + '-' + right('0' + RTRIM(CAST(DATEPART(month, Date) AS CHAR)),2) )
ELSE 0
END as 'Tonnes/Metres'

デバッグ用にも追加 

OperationalAssetDetail.Name

列の結果の 1 つとして、それが何であるかを視覚的に確認します。

この選択には多くの作業が必要です。
