I loaded 83 rows from my CSV file, but when I try to update the SQLite database I get 0 rows... I can't figure out what I'm doing wrong.

The program outputs:

Num rows loaded is 83
Num rows updated is 0

The source code is:

public void InsertData(String csvFileName, String tableName)
{
    String dir = Path.GetDirectoryName(csvFileName);
    String name = Path.GetFileName(csvFileName);

    using (OleDbConnection conn =
        new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
        dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited"""))
    {
        conn.Open();
        using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn))
        {
            QuoteDataSet ds = new QuoteDataSet();
            adapter.Fill(ds, tableName);
            Console.WriteLine("Num rows loaded is " + ds.Tags.Rows.Count);
            InsertData(ds, tableName);
        }
    }
}

public void InsertData(QuoteDataSet data, String tableName)
{
    using (SQLiteConnection conn = new SQLiteConnection(_connectionString))
    {

        using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn))
        {
            using (new SQLiteCommandBuilder(sqliteAdapter))
            {
                conn.Open();
                Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName));
            }
        }
    }
}

Any hints on why it's not updating the correct number of rows?
