Re: Auto Increment Problems....

Instead of incrementing to find the next row to count them, you dont have to set the ID if it is auto increment. MySQL will do it for you (and i think it might fill the holes too). Also, to get the num. of rows just do this - $get_rows = mysql_query("SELECT * FROM table"); $num_rows = mysql_num_rows($get_rows); "Georgie Casey" <webmaster@filmfind.tv> wrote in message news:20020729194732.70319.qmail@pb1.pair.com... > rite, > > my primary key column ("id") is set to auto_increment as usual which is very > handy.
