THanks for the quick response.

Thanks for the point to the previous post. I was unable to find it as I was not doing a search for merge.

Here is what I come up with this morning:

<?
include "connect.php";

//this is a class I use to do inserts and queries in mysql*********************************************
include "sequl.inc";


/* ******************************************
1) get sites already in sites and set new_site_id to its number

****************************************** */

$query ="select import_sites.*, sites.site_id as new from import_sites ";
$query.="right join sites ";
$query.="on import_sites.site_url=sites.site_url ";
$results=sequl::getit($query);
print_r($results);

foreach ($results as $result){
$old=$result['site_id'];
$new=$result['new'];
$update ="update import_sites set new_site_id=$new ";
$update.="where site_id=$old";
print "$update\n";
sequl::insert($update);

//update import_spider
$update="update import_spider set new_site_id=$new ";
$update.="where site_id=$old";
sequl::insert($update);
}

/* ******************************************
2) get new sites; they dont have new_site_id yet

****************************************** */
$query="select * from import_sites where new_site_id = 0";
$results=sequl::getit($query);
print_r($results);


foreach ($results as $result){
$old=$result['site_id'];
$url=$result['site_url'];

$insert="insert into sites (site_url) values ('$url')";
$new=sequl::insert($insert,1);

$update ="update import_sites set new_site_id=$new ";
$update.="where site_id=$old";

print "$update\n";
sequl::insert($update);

//update import_spider
$update="update import_spider set new_site_id=$new ";

sequl::insert($update);

}

In the demo where I tried this it seems to be working, I am sure there are some pitfalls but I have not uncovered them yet. What do you think?
