Ich habe eine Datenbank, die Lotterieformulareinreichungen von Benutzern speichert. Eine der Spalten ist eine DateTime-Spalte, die bei jeder Übergabe eines Formulars mit der aktuellen DateTime gefüllt wird. Ich möchte nach der DateTime-Spalte suchen können, damit ich alle an einem bestimmten Tag eingegebenen Formulare abrufen kann.DateTime-Suchprobleme ASP.NET
Ich bekomme keine Fehler, wenn ich die Suche, nur meine benutzerdefinierte Nachricht, dass "keine Ergebnisse mit diesem Suchkriterien übereinstimmen". Ich habe versucht, den jquery Datepicker zu deaktivieren und versuchte, das genaue DateTime Feld von der DB in das Suchfeld und noch nichts zu kopieren und einzufügen. Offensichtlich vermisse ich etwas, aber ich kann nicht herausfinden, was. Jede Hilfe wird sehr geschätzt.

Ich denke, man eine minimale Probe zu schaffen, die für die Replikation der Frage sieht in werden konnte. –
Es ist * wahrscheinlich *, dass Ihre Spalte eine Zeitkomponente hat, die Sie nicht faktorisieren - Sie können ein Datepicker-Datum (das wahrscheinlich als 'YYYY-MM-DDT00: 00: 00' analysiert) nicht mit einem' DATETIME' gleichsetzen Spalte, die eine Zeit enthält ('YYYY-MM-DDTHH: MM: SS'). Wahrscheinlich müssen Sie Ihre SQL-Suche in 'WHERE dateTime> = @ date1 UND dateTime <@ date2' ändern und '@ date1' als' DateTime.Parse (datumsuche.Text) .Date' und '@ date2' als' DateTime übergeben .Parse (datesearch.Text) .Date.AddDays (1) ', um sowohl den Zeitabschnitt als auch die Bereichssuche über den ausgewählten Tag hinweg abzubrechen. – jimbobmcgee
Danke jimbobmcgee, das hat den Trick gemacht. Obwohl ich sicher bin, dass C Sigmon's Antwort auch funktioniert hat. Ich habe es zuerst versucht. – HiCntry
