[PHP] Mass mySQL update...
So I populated a mySQL database but forgot to create random ids for each record. I have used phpmyadmin to add a varchar(15) column named id at the end of the database for each record, but now am wondering if there is an easy way to get random ID's into each of these... The column values for many of the entries are not unique, so I couldnt just loop through saying where term = $row[term] set id= rand(1, 9) any other ideas? Any way to refer to a particular row without matching values? Russ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

if you don't mind it being an int - try something like... ALTER TABLE table ADD ID INT NOT NULL INTEGER UNIQUE AUTO_INCREMENT, ADD PRIMARY KEY (ID); Reference: http://dev.mysql.com/doc/mysql/en/ALTER_TABLE.html Respectfully, Ligaya Turmelle --- Life is a game... so have fun. --- www.PHPCommunity.org Open Source, Open Community Visit for more information or to join the movement Russell P Jones wrote: So I populated a mySQL database but forgot to create random ids for each record.
