hehe, ok i would write a script that reads the existing data from the table and inserts it into a new one that has the same structure PLUS a primary key something like:
original_table:    name, description, whatever
new_table:        id, name, description, whatever
where id is primary key and auto_increment then <? if ($link=mysql_connect("host","user","pw") { mysql_select_db("the_correct_database); $result=mysql_query("SELECT * FROM original_table"); while (list($name,$description,$whatever) = mysql_fetch_row($result)) { mysql_query("INSERT INTO new_table (name,description,whatever) VALUES ($name,$description,$whatever)"); //that should add the id automatically } mysql_close($link) ?> then you can drop the original_table and rename the new_table to original_table i don't know if there's a better, more simple solution and i hope i did not forget anything important and it works this way Chris
