I am trying to write to a database using the following code. The code below works just fine, but how can I write an unknown amount of columns to a table?

So after the barcode I would need to write up to 47 new columns.

 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim conStr As String = "SERVER=PC167\DBTEST;Database =ORKA Test; trusted_connection= yes"
        Dim objcon As New SqlConnection(conStr)
        Dim obj As SqlCommand
        Dim strSQL As String
        Dim DoesTableExist As Boolean
        objcon.Open()
        If (objcon.State = ConnectionState.Open) Then
            MessageBox.Show("Open")
        End If
        If objcon.Database = "ORKA Test" Then
            MessageBox.Show("Database Exists")
        Else
        End If
        obj = objcon.CreateCommand()
        strSQL = "CREATE TABLE  DATA3" + "(Time VARCHAR(30), Date VARCHAR(30),Barcode VARCHAR (30))"
        obj.CommandText = strSQL
        obj.ExecuteNonQuery()
    End Sub
