Supplement with random / related to cart products Malformed SQL

I'll have to double check my current settings and update you, but I was getting an error about a bad query statement as it was including a where clause that filters out node ids that are already in the cart. However, if there are no products in the cart the list of nids is empty leaving the where clause as "NID NOT IN ()" which mysql doesn't like...

Easy solution, add an if statement to determine if the $filter_query string is set or not... ~line 215 in uc_upsell_core.inc...

The existing:

      $randoms = db_query("SELECT `nid`
                  FROM {node}
                  WHERE `status` = 1
                  AND `type` IN ('". implode("','", uc_product_product_types()) ."')
                  AND NOT nid IN (". $filter_query .")
                  ORDER BY RAND()");

Should be changed to:

    if ($filter_query) {
      $randoms = db_query("SELECT `nid`
                  FROM {node}
                  WHERE `status` = 1
                  AND `type` IN ('". implode("','", uc_product_product_types()) ."')
                  AND NOT nid IN (". $filter_query .")
                  ORDER BY RAND()");
    } else {
      $randoms = db_query("SELECT `nid`
                  FROM {node}
                  WHERE `status` = 1
                  AND `type` IN ('". implode("','", uc_product_product_types()) ."')
                  ORDER BY RAND()");
    }
