Question

So all is in my question. I have an web application in asp.net, with two databases :

The first ASPNETDB.MDF and the second MyApp.sdf

I would like to populate the tables of MyApp.sdf from an external file such as a txt file or something else.

Is this possible in Visual Studio 2010 ? Is there any way to do that ?

Thanks a lot in advance

Write a simple app:

    using (SqlConnection sqlcnn = new SqlConnection("Data Source=myapp.sdf"))
    {
        SqlCommand sqlcmd = new SqlCommand();
        sqlcmd.Connection = sqlcnn;

        sqlcnn.Open();

        StreamReader sr = new StreamReader(@"c:\mydir\myfile.txt");

        while (sr.Peek() != -1) // check for eof (end of file)
        {
            String line = sr.ReadLine();

            String[] values = line.Split(' '); // e.g if your values are seperated by space

            sqlcmd.CommandText = String.Format("INSERT INTO tableName VALUES ({0},{1},{2})", values[0], values[1], values[2]);

            sqlcmd.ExecuteNonQuery();
        }
    }
