Yes, you can do this slowly with PHP:

<?php
$data = mysql_query("SELECT x,y,z FROM db1.table WHERE where country='usa'");
$values = Array();
while ($row = mysql_fetch_assoc($data)) {
    // do some work...
    $row['x'] = mysql_real_escape_string($row['x']);
    $row['y'] = mysql_real_escape_string($row['y']);
    $row['z'] = mysql_real_escape_string($row['z']);
    $values[] = "('$row[x]','$row[y]','$row[z]')";
}
mysql_query("insert into db2.table (x,y,z) VALUES ".implode(',',$values)."");
?>

But i prefer quicker and simplier MySQL INSERT … SELECT statement, directly in MySQL console:

INSERT INTO db2.table (x,y,z) SELECT x,y,z FROM db1.table WHERE country='usa';
