Instead of "true" let insert() return the id. And while looking at your code: - You wrote in your DocBlocks, that the methods returns a boolean 0 or 1. Beside that this is wrong (0 or 1 are integers) you return either 'true' or nothing. You should return 'false' as well. - Returning a boolean to indicate the success of a method only makes sense, when "not successful" is a valid case, but I guess when 'delete()' fail it not be treatened as "normal". You should throw an Exception instead. This also includes: It's not required, that a method returns something in every case. If "delete()" for example doesn't have to tell something, it shouldn't. > > http://de.php.net/manual/en/function.mysql-insert-id.php > > 2 - how does one do aggrigate select queries like "SELECT SUM(price) FROM > mytable" ... what I tried seemed to fail... > Nothing "seems to fail" ;) Either it fails, or not (or it just doesn't behave, like expected, what I see as "fail" too).
