Мне нужно уметь добавлять, но есть ошибка. Синтаксическая ошибка INSERT INTO и cmd.ExecuteNonQuery()

Question

Dim cmd As New OleDb.OleDbCommand 
    If Not cnn.State = ConnectionState.Open Then 
     'open connection if it is not yet open 
     cnn.Open() 
    End If 

    cmd.Connection = cnn 
    'check whether add new or update 
    If Me.txtcheckID.Tag & "" = "" Then 
     'add new 
     'add data to table 
     cmd.CommandText = "INSERT INTO student(checkid, branch, amount, type, status, date, address) " & _ 
         " VALUES(" & Me.txtcheckID.Text & ",'" & Me.txtBranch.Text & "','" & _ 
         Me.cboType.Text & "','" & Me.txtStatus.Text & "','" & _ 
         Me.txtAddress.Text & "','" & Me.txtDate.Text & "','" & Me.txtAmount.Text & "')" 
     cmd.ExecuteNonQuery() 
    Else 
     'update data in table 
     cmd.CommandText = "UPDATE student " & _ 
        " SET checkid=" & Me.txtcheckID.Text & _ 
        ", branch='" & Me.txtBranch.Text & "'" & _ 
        ", type='" & Me.cboType.Text & "'" & _ 
        ", status='" & Me.txtStatus.Text & "'" & _ 
        ", address='" & Me.txtAddress.Text & "'" & _ 
        ", amount='" & Me.txtAmount.Text & "'" & _ 
        ", date='" & Me.txtDate.Text & "'" & _ 
        " WHERE checkid=" & Me.txtcheckID.Tag 
     cmd.ExecuteNonQuery() 
    End If 
    'refresh data in list 
    RefreshData() 
    'clear form 
    Me.btnClear.PerformClick() 

    'close connection 
    cnn.Close() 

Answer 1

cmd.CommandText = "INSERT INTO student(checkid, branch, amount, type, status, date, address) " & _ 
        " VALUES(" & Me.txtcheckID.Text & ",'" & Me.txtBranch.Text & "','" & _ 
        Me.cboType.Text & "','" & Me.txtStatus.Text & "','" & _ 
        Me.txtAddress.Text & "','" & Me.txtDate.Text & "','" & Me.txtAmount.Text & "')" 

Извините, если я глуп, но будет иметь 2 места в строке CommandText между адресом) и ЗНАЧЕНИЯ, где первый разрыв строки вызывает ошибочными? Не знаете, как VB и OleDB обрабатывают пробелы, а моя учетная запись слишком новая, чтобы комментировать ...
