Description:
------------
mysql_insert_id return wrong ID. It will add new line to DB correctly but when using mysql_insert_id to get auto_increment value, it will return something odd.



Reproduce code:
---------------
function add_line()
{
global $db_insert;
$aikaleima = time();

if ( (isset($_SESSION['admin']['rekisteriID'])) && (strlen($_SESSION['admin']['rekisteriID']) > 0) )
{
$query = sprintf("
insert into rekisteri_rekisteriID (rekisteriID, oletus, lisatty, lisaaja)
values (%s, 1, %u, %u)",
sql_valid($_SESSION['admin']['rekisteriID']),
sql_valid($aikaleima),
sql_valid($_SESSION['user']['userID']));

if ( (isset($db_insert)) && (isset($query)) )
{
$result = $db_insert->query($query);
unset($query);
}

if ( (isset($result)) && (mysql_affected_rows() > 0) )
{
$rekisterinro = mysql_insert_id();
}
....

Expected result:
----------------
Example value should be 29171.

Actual result:
--------------
Value is 7618. And ID 7618 is already reserved in DB.

>Here is all code what U will need...
I don't need *all* your code, I need only a small reproduce code that doesn't use any external resources (except MySQL, of course).
Please, reduce the code, as I'm unable to run it without your session data, functions used, contants etc. etc.
Also, provide a table structure dump (you can also provide some sample data).
Put in somewhere in the net and post URL here if possible.

Problem is that the code is not public (the previous one that I published, is now public but everything else will not be. Boss will hang me if I publish code more). Even DB's are closed. I have tested that the sample code is making same error all the time, so nothing else is needed.

Let's make it simple:

When you make query in class 1, the query is ok and it will return  to mysql_insert_id() correct value.

When you make query in class 2, the query is ok (everything in DB [MySQL] is ok and correct values have been inserted) BUT mysql_insert_id() is getting value from query 1 (class 1), not from query 2 like it should be.

Without classes everything is ok (all code is working without problems), but with classes everything goes straight to...

Class 1 is STAT and class 2 is ADMIN_DOG_SQL. Is that clear now?

What we can't reproduce we can't fix. So either provide the short example script as requested or let this report rot.
