WordPress Multi DB missed table

My script code is this:

<?php
error_reporting(E_ALL);
$db_connect = mysql_connect("localhost","root","");
if (!$db_connect) {
  die('Could not connect: ' . mysql_error());
}

mysql_select_db("wpmu_global", $db_connect);
$sqlid = "SELECT * FROM wp_blogs";
$result1 = mysql_query($sqlid) or die(mysql_error());

while($row = mysql_fetch_array($result1)){
	$blogid = array($row['blog_id']);
	$data = $row['blog_id'];
}
mysql_close($db_connect);

$db_connect = mysql_connect("localhost","root","");
if (!$db_connect) {
  die('Could not connect: ' . mysql_error());
}

mysql_select_db("wpmu_1", $db_connect); //first db and i will run script for each db

foreach ($blogid as &$data) {
echo $sql = "CREATE TABLE IF NOT EXISTS <code>wp_&quot;.$data.&quot;_commentmetaTest</code> (
  <code>meta_id</code> bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  <code>comment_id</code> bigint(20) unsigned NOT NULL DEFAULT '0',
  <code>meta_key</code> varchar(255) DEFAULT NULL,
  <code>meta_value</code> longtext,
  PRIMARY KEY (<code>meta_id</code>),
  KEY <code>comment_id</code> (<code>comment_id</code>),
  KEY <code>meta_key</code> (<code>meta_key</code>)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1";
}

$result = mysql_query($sql) or die(mysql_error());

mysql_close($db_connect);
?>

if the multi db plugin skipped the extra tables, talk to the people you got the plugin from.

actually, Multi DB seems works because newly created blogs have required table. Problem is on old ones and that is why i have created this script for to create tables on DBs. This code not works because of Multi DB as i understand.

Read this:

And go back to where you got the plugin from and ask them how they handled it with multi dbs.

ahh perfect that is what i am trying to create. They have created it as plugin which i have not thought that way lol.

Thank you very much Andrea_r ??
