無法使用vb.net將數據保存到sql

我試圖將數據保存到已從SQL Server分離並添加到解決方案資源管理器中的APP_DATA文件夾的mdf文件，但我無法做到這一點。您的幫助將不勝感激。謝謝！這裏是我的代碼：無法使用vb.net將數據保存到sql

Dim con As New SqlConnection 
    Dim cmd As New SqlCommand 

    Dim EmployeeNo As Integer 
    Dim EmployeeName As String 
    Dim SupervisorName As String 
    Dim DateCreated As Date 
    Dim WeekRange As String 
    Dim MonthRange As String 
    Dim ScheduleIn As String 
    Dim ScheduleOut As String 
    Dim WorkStatus As String 

    EmployeeNo = EmpNoText.Text 
    EmployeeName = EmpNameText.Text 
    SupervisorName = TeamLeadDropDown.Text 
    DateCreated = DateCreatedTextBox.Text 
    WeekRange = WeekRangeTextBox.Text 
    MonthRange = MonthDropDown.Text 
    ScheduleIn = ScheduleInBox.Text 
    ScheduleOut = ScheduleOutBox.Text 
    WorkStatus = StatusDropDown.Text 


    Try 
     con.ConnectionString = "Data Source=(LocalDB)\v11.0;AttachDbFilename=C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA\JIBKPI.mdf;Initial Catalog=JIBKPI;Integrated Security=True" 
     con.Open() 
     cmd.Connection = con 
     cmd.CommandText = "INSERT INTO AgentAttendance ([EmployeeNo], [EmployeeName], [SupervisorName], [DateCreated], [WeekRange], [MonthRange], [ScheduleIn], [ScheduleOut], [WorkStatus]) VALUES (@EmployeeNo, @EmployeeName, @SupervisorName, @DateCreated, @WeekRange, @MonthRange, @ScheduleIn, @ScheduleOut, @WorkStatus,)" 
     cmd.ExecuteNonQuery() 
     MsgBox("Successfuly saved!", MsgBoxStyle.Information + MsgBoxStyle.OkOnly) 
    Catch ex As Exception 
     MsgBox("Error: Unable to save data.") 
    Finally 
     con.Close() 
    End Try

在我的web.config連接字符串：

<connectionStrings> 
<add name="JIBKPIConnectionString" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=&quot;C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA\JIBKPI.mdf&quot;;Initial Catalog=JIBKPI;Integrated Security=True" providerName="System.Data.SqlClient"/>

你有文件設置爲設計師始終複製？ – APrough

你有什麼錯誤？ –

如果您沒有使用它，則web.config設置是無用的。 –

看你的代碼，我注意到的第一件事是，你使用的參數您的查詢：

cmd.CommandText = "INSERT INTO AgentAttendance ([EmployeeNo], [EmployeeName], [SupervisorName], [DateCreated], [WeekRange], [MonthRange], [ScheduleIn], [ScheduleOut], [WorkStatus]) VALUES (@EmployeeNo, @EmployeeName, @SupervisorName, @DateCreated, @WeekRange, @MonthRange, @ScheduleIn, @ScheduleOut, @WorkStatus,)"

但是你沒有實際設置這些參數。所以在執行查詢之前，您需要創建這些參數。喜歡的東西：

cmd.Parameters.Add("@EmployeeNo", SqlDbType.Int) 
command.Parameters("@EmployeeNo").Value = EmployeeNo 
etc...

然後執行查詢：

cmd.ExecuteNonQuery()

另外，如果你要使用的連接字符串中你的web.config，從AttachDbFilename同時刪除& QUOT

更改此：

AttachDbFilename=&quot;C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA\JIBKPI.mdf&quot;

這樣：

AttachDbFilename=C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA\JIBKPI.mdf

編輯：從查詢中刪除最後一個逗號@WorkStatus

後成爲

@WorkStatus)"
