QuestionAnswer45edited Feb 18, 2009 at 15:39I'd recommend reading How MySQL Uses Indexes from the MySQL Reference Manual. It states that indexes are used... To eliminate rows from consideration. To retrieve rows from other tables when performing joins. To sort or group a table (under certain conditions). To optimize queries using only indexes without consulting the data rows.
