Question List parameters support? about dbhelpers

[coolblabla]

and do I have to use var transaction = connection.BeginTransaction(); instead of connection?

using (var connection = db.CreateConnection()) {
    connection.Open();
    db.ExecuteNonQuery(..., connection);
    db.ExecuteNonQuery(..., connection);
    db.ExecuteNonQuery(..., connection);
    return db.ExecuteScalar<int>(..., connection);
}
