Question

我今天要尝试排序。我在比较时给出了匹配错误。

OleDbConnection baglanti = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Users\\Dragonfly\\Documents\\Visual Studio 2013\\WebSites\\WebSite2\\App_Data\\calismagunluk.mdb");
OleDbDataReader oku;
OleDbCommand sorgu =new OleDbCommand();
DateTime bugun = DateTime.Now.Date;
sorgu.CommandText = "select * from calisan where kulID=" + sesionKulId + 
    " AND gun='" + bugun + "' ";
 oku = sorgu.ExecuteReader();//I give error in here
    if (oku.HasRows) { 
    Repeater1.DataSource = oku;
    Repeater1.DataBind();
    oku.Dispose();}
    else{
        Repeater1.Visible = false;
        repeaterBos.Text = "Bugün Hiç Çalışma Yapmamışsınız...";
        oku.Dispose();
    }

我收到此错误：＆＃34;标准表达式中的数据类型不匹配＆＃34;。

如果我将db列更改为Text，则它正在运行。但我不是这样想的。我该怎么做？

您可以绕过格式问题，并通过使用参数让命令自行处理格式：

OleDbConnection baglanti = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Users\\Dragonfly\\Documents\\Visual Studio 2013\\WebSites\\WebSite2\\App_Data\\calismagunluk.mdb");
OleDbDataReader oku;
OleDbCommand sorgu =new OleDbCommand();
DateTime bugun = DateTime.Now.Date;
sorgu.CommandText = "select * from calisan where kulID=@ID AND gun=@date";
sorgu.Parameters.Add("@ID", OleDbType.Integer).Value = susionKulId;
sorgu.Parameters.Add("@date", OleDbType.DBTimeStamp).Value = bugun;

ASP.Net与访问日期/时间列不匹配
