Thanks to all that have helped. I am inclined at Robert's suggestion below that would free me from worrying about locking issues. Thanks everybody.

Quoting Robert Sossomon <LoneWolf@xxxxxxxxx>:
> CREATE TABLE `users` (
> `num` int(10) NOT NULL auto_increment,
> `name` varchar(100) NOT NULL default '',
> `login` varchar(100) NOT NULL default '',
> `password` varchar(20) NOT NULL default '',
> PRIMARY KEY (`num`),
> KEY `num` (`num`)
> ) TYPE=MyISAM AUTO_INCREMENT=12345 ;
>
> That should help out. When creating the table in mysql you can set the
> auto_increment number on the last line, which when you add a new user the
> query
> looks like:
>
> insert into users values('','name','login','pass');
>
> leaving the first field empty makes it automatically increase it. The beauty
> is
> that you can have 40000000000 people registering at once, and their number
> gets
> assigned as the query is run against the database, no matter what order they
> hit
> it in, the system will take it as they come.
