SQL Error

I get an error when going to;

Theme setup>Listing Packages>Statistics
Choosing ‘Transfer Listings’ ‘Everything Else’>’Custom’

Warning: mysqli_query() expects parameter 1 to be mysqli, string given in /REDACTED/themes/CT/framework/admin/_5.php on line 52

Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, null given in /REDACTED/themes/CT/framework/admin/_5.php on line 53

if(isset($_POST[‘TransferFormListings’]) && is_numeric($_POST[‘from’]) && is_numeric($_POST[‘to’])){

if($_POST[‘from’] == “-2”){

$SQL = “SELECT “.$wpdb->prefix.”posts.ID, mt2.meta_value FROM “.$wpdb->prefix.”posts
LEFT JOIN “.$wpdb->prefix.”postmeta AS mt2 ON (“.$wpdb->prefix.”posts.ID = mt2.post_id AND mt2.meta_key = ‘packageID’)
WHERE “.$wpdb->prefix.”posts.post_type = ‘”.THEME_TAXONOMY.”_type’
AND ( “.$wpdb->prefix.”posts.post_status = ‘draft’ OR “.$wpdb->prefix.”posts.post_status = ‘publish’ )
AND mt2.meta_key IS NULL
GROUP BY “.$wpdb->prefix.”posts.ID”;
LINE 52 $result = mysql_query($SQL, $wpdb->dbh);
LINE 53 if (mysql_num_rows($result) > 0) {
while ($val = mysql_fetch_object($result)){
update_post_meta($val->ID,’packageID’,$_POST[‘to’]);
}
}

Wondering if this is a bug
