MySql should insert a value into that column when you update if you are using an
auto_increment field. this value will always be unique. period.

Subject: [PHP] problem with mysql / auto increment fields.. ?
On my website there are a couple places where people can sign up ..
The querys after the sign up process look like
$blahblah = query(insert firstname lastname) values (blah blah blah)
$userid = mysql_insert_id($blahblah);
$insertintoothertable = query(userid, blah blah blah) etc.
it then uses this userid var to insert them into a variety of other tables
for other things on the site, such as a phpBB account, etc.
if multiple people are signing up for accounts at different places, is there
the possibility that a duplicate userid could be assigned, or anything like
that?
Thanks,
Chad
