ライン・ウィークリー・レポート

Question

私はこのレポートに対して2つの日付を選択するライン・ウィークリー・レポートを作成しています。たとえば、ユーザーは2つの日付の間でデータを表示する必要があります。私はWebアプリケーションでやっています。これは、SQL Serverで実行しますが、ときに私は、文字を変換する際

の変換が失敗したように、それはエラーを示しています私のアプリケーションでそれを含めています

：私はこのようなコードを書かれている

string to smalldatetimeデータ型。

誰もが私にこれを助けることができますか？

Answer 1

代わりのtxtfromdateとtxttodateのための文字列連結を使用してあなたがDateTime、またはSqlDateTimeに変換した後、パラメータとして渡す試してください。あなたの問題は、ほとんどの場合、これらのコントロールのテキストがSQL Serverが解釈できないようにフォーマットされているかどうかにあります。
