Bu sorgu başarısız neden merhaba herkes görebilir?

SELECT  A.idAd, A.ads_in_Cat, A.title, A.currency, A.price, 
A.in_dpt, A.description, A.featured FROM ads A
LEFT JOIN featured F ON F.ad = A.idAd
INNER JOIN dept D ON D.id_dept = A.in_dpt
INNER JOIN sub_cat_ad S ON S.id_sub_cat = A.ads_in_Cat
INNER JOIN cat_ad C ON C.idCat_ad = S.from_cat_ad 
ORDER BY A.featured DESC LIMIT :limit, :offset

Ama bu çalışır:

SELECT *FROM ads 
LEFT JOIN featured ON featured.ad = ads.idAd
INNER JOIN dept ON dept.id_dept = ads.in_dpt
INNER JOIN sub_cat_ad ON id_sub_cat = ads.ads_in_Cat
INNER JOIN cat_ad ON idCat_ad = sub_cat_ad.from_cat_ad
ORDER BY featured DESC LIMIT :limit, :offset

İlkinde, ben sorgu kadar tek sütun döndüren, masa "reklamları" tüm sütunları istemiyorum ...FROM ads A.
