私はストアドプロシージャを持っています。その本体では、1つのフィールドがnvarcharであるデータを選択しますが、日付が含まれています（最初の18文字はテキストだけですが、日付です）。次に、その日付を別の日付（実際の日付）と比較する条件を使用します。変換のSQL Server SqlClientの奇妙な例外
Select (bla bla) from (bla bla)
where DATEDIFF(DAY,DueDateDay,CAST(SUBSTRING(myField,18,10) as datetime)) < @dayCount
このSPは素晴らしい動作をします。私はSqlCommand.ExecuteReader()を使用して、私の.NETアプリケーションからこのSPを呼び出すとき、それは例外をスロー：
datetimeデータ型 にnvarcharデータ型の変換は範囲外の値になりました。
なぜですか？
