如何构建查询以按字母顺序按vl_name（vldescription）对结果进行排序，并使用vlk_addeddate将表vllinks从最新的内部限制等于1进行分类？
SELECT
aa.vl_id, aa.vl_name, aa.vl_code, aa.vl_vcc, aa.vl_description,
bb.vlk_id, bb.vlk_vlid, bb.vlk_link, bb.vlk_platform, bb.vlk_location, bb.vlk_addeddate,
le.vop_vlid, le.vop_thumbnail,
cx.vcc_id, cx.vcc_type, cx.vcc_brand, cx.vcc_variant
FROM vldescription AS aa
LEFT JOIN vllinks AS bb ON aa.vl_id = bb.vlk_vlid
LEFT JOIN vlofferphotos AS le ON le.vop_vlid = aa.vl_id
LEFT JOIN vlcarcats AS cx ON cx.vcc_id = aa.vl_vcc
WHERE aa.vl_vcc = '$change_me_if_you_need'
GROUP BY vl_id
ORDER BY vl_name
