Insert MySQL

Prosím vie mi niekto minimalizovať tento SQL do jedného? Už neviem ako tieto 2 dať do 1. $quer = $mysqli->query("SELECT ID FROM campaign WHERE client_id = '" . $mysqli->escape($client_id) . "'"); $row = $query->fetch_assoc(); $campaign_id = $row; $quer = $mysqli->query("INSERT INTO keyword (c_word, date, position, AvgCpc, impression, clicks, cost, quality, ctr, type, MaxCpc) SELECT ID, '" . date("Y-m-d") . "', '" . $mysqli->escape($position) . "', '" . $mysqli->escape($AvgCpc) . "', '" . $mysqli->escape($impression) . "', '" . $mysqli->escape($clicks) . "', '" . $mysqli->escape($cost) . "', '" . $mysqli->escape($quality) . "', '" . $mysqli->escape($ctr) . "', '" . $mysqli->escape($type) . "', '" . $mysqli->escape($MaxCpc) . "' FROM keywords WHERE keyword = '" . $mysqli->escape($db_word) . "' AND campaign = " . $campaign_id . " ");

Pokud jsem správně pochopil: $quer = $mysqli->query("INSERT INTO keyword (c_word, date, position, AvgCpc, impression, clicks, cost, quality, ctr, type, MaxCpc) SELECT ID, '" . date("Y-m-d") . "', '" . $mysqli->escape($position) . "', '" . $mysqli->escape($AvgCpc) . "', '" . $mysqli->escape($impression) . "', '" . $mysqli->escape($clicks) . "', '" . $mysqli->escape($cost) . "', '" . $mysqli->escape($quality) . "', '" . $mysqli->escape($ctr) . "', '" . $mysqli->escape($type) . "', '" . $mysqli->escape($MaxCpc) . "' FROM keywords WHERE keyword = '" . $mysqli->escape($db_word) . "' AND campaign = (SELECT ID FROM campaign WHERE client_id = '" . $mysqli->escape($client_id) . "' LIMIT 1) ");
