Question

How can I know if the following INSERT query succeeded?

MySqlConnection connection = new MySqlConnection(ConnectionString);
connection.Open();
MySqlCommand command = new MySqlCommand("INSERT INTO People (PersonName, dateAdded) VALUES (?name, NOW())", connection);
command.Parameters.Add(new MySqlParameter("name", Name));
MySqlDataReader Reader = command.ExecuteReader();

I tried running Reader.Read() but only an empty string is returned. Thanks.

Don’t use ExecuteReader if you’re doing an INSERT, UPDATE or DELETE. Use ExecuteNonQuery instead, it’ll return the number of affected rows.
