Hi guys,
I never can get mysql_insert_id?
Is this broken with PHP4?
Please let me know if you can get it to work. or work around.
Thanks.

Hi DL,
the only problem i can think of might occur with pconnect is,
last_insert_id() will return you the last inserted ID from
previous 'session', not current 'session'.
to prevent this, you should call last_insert_id() only when
your INSERT query executed succesfully.

Hi DL,
=session is not the correct word/its use is potentially confusing
(perhaps that's why it's in quotes?) - persistence refers to the
continuing connection between PHP and MySQL.
yup, you're right.
session is not the correct word, but i can't find the
correct/easy word to subtitute
Jimmy,
However it is also possible that in order to save time the LAST_ID
information is built into the resultset coming back from the INSERT -
thus when mysql_insert_id() is called PHP would not need to go back
to MySQL/last_insert_id().
yes, what you said could be true also.
Well,
Hi,
Is it possible that I would get the wrong ID (Not the ID I just inserted in
Auto_Increment field) by using mysql_insert_id function if someone is also
inserting record at the same time? How does mysql_insert_id work accurately?
Thanks,
Wee

In my code I have a few places where I use mysql_pconnect to open a

use mysql_insert_id to fetch insert ids for various insert commands.
Since mysql_pconnect uses the SAME database connection between my php

Most of the time, it returns the proper value. However,

Subject: RE: [PHP] mysql_insert_id()
You probably stated this in your previous post, but what is
the result from your call to mysql() ? Is this call failing so
that when you get to mysql_insert_id(), the id doesn't exist?
I did. It's returning a numerical one (1).
What I'm doing now
Instead of checking if(!$id), perhaps you would be better off to check the
result of your query (which in this example was successful, since you got
a return from mysql() ).
