Thanks for the clarification with the returns. I made the changes however and it still doesn't work. This code comes pretty much straight off the presses from http://www.onlamp.com/lpt/a/832 What I have is quite modified from what is on there as it is quite buggy to begin with. Anyway, It still doesn't work. In perl, this would have been done already. I can't be the first person to try running sessions on a database. Does anyone have a session.inc file that would be appropriate for me. I feel like it should just be in the php base files. > -----Original Message----- > From: Rasmus Lerdorf [mailto:rasmus@php.net] > Sent: Friday, November 15, 2002 4:59 PM > To: Adam Nelson > Cc: php-db@lists.php.net > Subject: Re: php sessions using mysql (or any db) > > > > CREATE TABLE `SessionsTable` ( > > `SID` varchar(32) NOT NULL default '', > > This doesn't need to be a varchar.

I don't know the specifics, but I think char is no longer used by InnoDB (ie. it is just an alias for varchar).
