Hi,

Is this code solid? I've tried to use "using" etc. Basically a method to pass as sequenced list of SQL commands to be run against a Sqlite database.

I assume it is true that in sqlite by default all commands run in a single connection are handled transactionally? Is this true? i.e. I should not have to (and haven't got in the code at the moment) a BeginTransaction, or CommitTransaction.

It's using http://sqlite.phxsoftware.com/ as the sqlite ADO.net database provider.

private int ExecuteNonQueryTransactionally(List<string> sqlList)
{
    int totalRowsUpdated = 0;

    using (var conn = new SQLiteConnection(_connectionString))
    {
        // Open connection (one connection so should be transactional - confirm)
        conn.Open();

        // Apply each SQL statement passed in to sqlList
        foreach (string s in sqlList)
        {
            using (var cmd = new SQLiteCommand(conn))
            {
                cmd.CommandText = s;
                totalRowsUpdated = totalRowsUpdated + cmd.ExecuteNonQuery();
            }
        }
    }

    return totalRowsUpdated;
}
