これは、サブクエリが=、=、<, <= , >、> =

Question

は、私は以下のようにwhere句で条件に関するテーブル内のいくつかの値を更新するには、SQLの仕事を構築している次の時に許可されていません！

Update c set isLoaded = 0 , LoadingState = 'L', isSent = 0 
    from Container c 
    where c.isloaded = 1 and DATEDIFF(second, dateadd(HOUR, c.LoadingInterval,c.entrydate), getdate())/3600.0 between c.LoadingInterval and (c.LoadingInterval + 2) 

私はこのスクリプトを実行しようとすると、しかし、次のエラーが登場：

メッセージ512、レベル16は、状態1、プロシージャUpdateContainersStatistcs、ラインが 9サブクエリは複数の値を返しました。 サブクエリが、=、！<、< =、>、> =、またはサブクエリが式 として使用されている場合は、これは許可されません。ステートメントは終了されました。

理由は表に作成されたトリガーのためです。 私はこのトリガーを無効にし、すべてがうまく機能している トリガスクリプトは以下の通りです：

クエリは完全に正しいですが、エラーの理由は、同じテーブルの上に作成されたトリガました。

テーブルのトリガーを無効にしたところ、すべて正常に動作しています。
